+ * The goal of these types is to provide source code portability across

+ *
+ * 1) The following types are of fixed size for all targets (16/32/64):
+ *
+ * u8           Logical boolean
+ *
+ * u8           8-bit  (1 byte) unsigned value
+ * u16          16-bit (2 byte) unsigned value
+ * u32          32-bit (4 byte) unsigned value
+ * u64          64-bit (8 byte) unsigned value
+ *
+ * s16          16-bit (2 byte) signed value
+ * s32          32-bit (4 byte) signed value
+ * s64          64-bit (8 byte) signed value
+ *
+ * COMPILER_DEPENDENT_UINT64/s64 - These types are defined in the
+ * compiler-dependent header(s) and were introduced because there is no common
+ * 64-bit integer type across the various compilation models, as shown in
+ * the table below.
+ *
+ * Datatype  LP64 ILP64 LLP64 ILP32 LP32 16bit
+ * char      8    8     8     8     8    8
+ * short     16   16    16    16    16   16
+ * _int32         32
+ * int       32   64    32    32    16   16
+ * long      64   64    32    32    32   32
+ * long long            64    64
+ * pointer   64   64    64    32    32   32
+ *
+ * Note: ILP64 and LP32 are currently not supported.
+ *
+ *
+ * 2) These types represent the native word size of the target mode of the
+ * processor, and may be 16-bit, 32-bit, or 64-bit as required. They are
+ * usually used for memory allocation, efficient loop counters, and array
+ * indexes. The types are similar to the size_t type in the C library and are
+ * required because there is no C type that consistently represents the native
+ * data width. acpi_size is needed because there is no guarantee that a
+ * kernel-level C library is present.

+/* Comment by Rik:
+ *
+ * For some background on GF(2^128) see for example: 
+ * http://csrc.nist.gov/groups/ST/toolkit/BCM/documents/proposedmodes/gcm/gcm-revised-spec.pdf 
+ *
+ * The elements of GF(2^128) := GF(2)[X]/(X^128-X^7-X^2-X^1-1) can
+ * be mapped to computer memory in a variety of ways. Let's examine
+ * three common cases.
+ *
+ * Take a look at the 16 binary octets below in memory order. The msb's
+ * are left and the lsb's are right. char b[16] is an array and b[0] is
+ * the first octet.
+ *
+ * 80000000 00000000 00000000 00000000 .... 00000000 00000000 00000000
+ *   b[0]     b[1]     b[2]     b[3]          b[13]    b[14]    b[15]
+ *
+ * Every bit is a coefficient of some power of X. We can store the bits
+ * in every byte in little-endian order and the bytes themselves also in
+ * little endian order. I will call this lle (little-little-endian).
+ * The above buffer represents the polynomial 1, and X^7+X^2+X^1+1 looks
+ * like 11100001 00000000 .... 00000000 = { 0xE1, 0x00, }.
+ * This format was originally implemented in gf128mul and is used
+ * in GCM (Galois/Counter mode) and in ABL (Arbitrary Block Length).
+ *
+ * Another convention says: store the bits in bigendian order and the
+ * bytes also. This is bbe (big-big-endian). Now the buffer above
+ * represents X^127. X^7+X^2+X^1+1 looks like 00000000 .... 10000111,
+ * b[15] = 0x87 and the rest is 0. LRW uses this convention and bbe
+ * is partly implemented.
+ *
+ * Both of the above formats are easy to implement on big-endian
+ * machines.
+ *
+ * EME (which is patent encumbered) uses the ble format (bits are stored
+ * in big endian order and the bytes in little endian). The above buffer
+ * represents X^7 in this case and the primitive polynomial is b[0] = 0x87.
+ *
+ * The common machine word-size is smaller than 128 bits, so to make
+ * an efficient implementation we must split into machine word sizes.
+ * This file uses one 32bit for the moment. Machine endianness comes into
+ * play. The lle format in relation to machine endianness is discussed
+ * below by the original author of gf128mul Dr Brian Gladman.
+ *
+ * Let's look at the bbe and ble format on a little endian machine.
+ *
+ * bbe on a little endian machine u32 x[4]:
+ *
+ *  MS            x[0]           LS  MS            x[1]		  LS
+ *  ms   ls ms   ls ms   ls ms   ls  ms   ls ms   ls ms   ls ms   ls
+ *  103..96 111.104 119.112 127.120  71...64 79...72 87...80 95...88
+ *
+ *  MS            x[2]           LS  MS            x[3]		  LS
+ *  ms   ls ms   ls ms   ls ms   ls  ms   ls ms   ls ms   ls ms   ls
+ *  39...32 47...40 55...48 63...56  07...00 15...08 23...16 31...24
+ *
+ * ble on a little endian machine
+ *
+ *  MS            x[0]           LS  MS            x[1]		  LS
+ *  ms   ls ms   ls ms   ls ms   ls  ms   ls ms   ls ms   ls ms   ls
+ *  31...24 23...16 15...08 07...00  63...56 55...48 47...40 39...32
+ *
+ *  MS            x[2]           LS  MS            x[3]		  LS
+ *  ms   ls ms   ls ms   ls ms   ls  ms   ls ms   ls ms   ls ms   ls
+ *  95...88 87...80 79...72 71...64  127.120 199.112 111.104 103..96
+ *
+ * Multiplications in GF(2^128) are mostly bit-shifts, so you see why
+ * ble (and lbe also) are easier to implement on a little-endian
+ * machine than on a big-endian machine. The converse holds for bbe
+ * and lle.
+ *
+ * Note: to have good alignment, it seems to me that it is sufficient
+ * to keep elements of GF(2^128) in type u64[2]. On 32-bit wordsize
+ * machines this will automatically aligned to wordsize and on a 64-bit
+ * machine also.
+ */
+/*	Multiply a GF128 field element by x. Field elements are held in arrays
+    of bytes in which field bits 8n..8n + 7 are held in byte[n], with lower
+    indexed bits placed in the more numerically significant bit positions
+    within bytes.
+
+    On little endian machines the bit indexes translate into the bit
+    positions within four 32-bit words in the following way
+
+    MS            x[0]           LS  MS            x[1]		  LS

+ *	  state of the HASH transformation at the begining. This shall fill in
+ *	  the internal structures used during the entire duration of the whole
+ *	  transformation. No data processing happens at this point.
+ * @update: Push a chunk of data into the driver for transformation. This
+ *	   function actually pushes blocks of data from upper layers into the
+ *	   driver, which then passes those to the hardware as seen fit. This
+ *	   function must not finalize the HASH transformation by calculating the
+ *	   final message digest as this only adds more data into the
+ *	   transformation. This function shall not modify the transformation
+ *	   context, as this function may be called in parallel with the same
+ *	   transformation object. Data processing can happen synchronously
+ *	   [SHASH] or asynchronously [AHASH] at this point.
+ * @final: Retrieve result from the driver. This function finalizes the
+ *	   transformation and retrieves the resulting hash from the driver and
+ *	   pushes it back to upper layers. No data processing happens at this
+ *	   point.
+ * @finup: Combination of @update and @final. This function is effectively a
+ *	   combination of @update and @final calls issued in sequence. As some
+ *	   hardware cannot do @update and @final separately, this callback was
+ *	   added to allow such hardware to be used at least by IPsec. Data
+ *	   processing can happen synchronously [SHASH] or asynchronously [AHASH]
+ *	   at this point.
+ * @digest: Combination of @init and @update and @final. This function
+ *	    effectively behaves as the entire chain of operations, @init,
+ *	    @update and @final issued in sequence. Just like @finup, this was
+ *	    added for hardware which cannot do even the @finup, but can only do
+ *	    the whole transformation in one run. Data processing can happen
+ *	    synchronously [SHASH] or asynchronously [AHASH] at this point.
+ * @setkey: Set optional key used by the hashing algorithm. Intended to push
+ *	    optional key used by the hashing algorithm from upper layers into
+ *	    the driver. This function can store the key in the transformation
+ *	    context or can outright program it into the hardware. In the former
+ *	    case, one must be careful to program the key into the hardware at
+ *	    appropriate time and one must be careful that .setkey() can be
+ *	    called multiple times during the existence of the transformation
+ *	    object. Not  all hashing algorithms do implement this function as it
+ *	    is only needed for keyed message digests. SHAx/MDx/CRCx do NOT
+ *	    implement this function. HMAC(MDx)/HMAC(SHAx)/CMAC(AES) do implement
+ *	    this function. This function must be called before any other of the
+ *	    @init, @update, @final, @finup, @digest is called. No data
+ *	    processing happens at this point.
+ * @export: Export partial state of the transformation. This function dumps the
+ *	    entire state of the ongoing transformation into a provided block of
+ *	    data so it can be @import 'ed back later on. This is useful in case
+ *	    you want to save partial result of the transformation after
+ *	    processing certain amount of data and reload this partial result
+ *	    multiple times later on for multiple re-use. No data processing
+ *	    happens at this point.
+ * @import: Import partial state of the transformation. This function loads the
+ *	    entire state of the ongoing transformation from a provided block of
+ *	    data so the transformation can continue from this point onward. No
+ *	    data processing happens at this point.

+ *
+ * The .name field may be used to specify the name of the I2C adapter. If set to
+ * NULL, dev_name() of .dev will be used.
+ *
+ * Drivers provide a hardware-specific implementation of how transactions
+ * are executed via the .transfer() function. A pointer to a drm_dp_aux_msg
+ * structure describing the transaction is passed into this function. Upon
+ * success, the implementation should return the number of payload bytes
+ * that were transferred, or a negative error-code on failure. Helpers
+ * propagate errors from the .transfer() function, with the exception of
+ * the -EBUSY error, which causes a transaction to be retried. On a short,
+ * helpers will return -EPROTO to make it simpler to check for failure.
+ *
+ * An AUX channel can also be used to transport I2C messages to a sink. A
+ * typical application of that is to access an EDID that's present in the
+ * sink device. The .transfer() function can also be used to execute such
+ * transactions. The drm_dp_aux_register_i2c_bus() function registers an
+ * I2C adapter that can be passed to drm_probe_ddc(). Upon removal, drivers
+ * should call drm_dp_aux_unregister_i2c_bus() to remove the I2C adapter.
+ * The I2C adapter uses long transfers by default; if a partial response is
+ * received, the adapter will drop down to the size given by the partial
+ * response for this transaction only.
+ *
+ * Note that the aux helper code assumes that the .transfer() function
+ * only modifies the reply field of the drm_dp_aux_msg structure.  The
+ * retry logic and i2c helpers assume this is the case.

+ * This header provides constants for binding nvidia,tegra30-car.
+ *
+ * The first 130 clocks are numbered to match the bits in the CAR's CLK_OUT_ENB
+ * registers. These IDs often match those in the CAR's RST_DEVICES registers,
+ * but not in all cases. Some bits in CLK_OUT_ENB affect multiple clocks. In
+ * this case, those clocks are assigned IDs above 160 in order to highlight
+ * this issue. Implementations that interpret these clock IDs as bit values
+ * within the CLK_OUT_ENB or RST_DEVICES registers should be careful to
+ * explicitly handle these special cases.
+ *
+ * The balance of the clocks controlled by the CAR are assigned IDs of 160 and
+ * above.

+ *
+ * Common interface definitions for making balloon pages movable by compaction.
+ *
+ * Despite being perfectly possible to perform ballooned pages migration, they
+ * make a special corner case to compaction scans because balloon pages are not
+ * enlisted at any LRU list like the other pages we do compact / migrate.
+ *
+ * As the page isolation scanning step a compaction thread does is a lockless
+ * procedure (from a page standpoint), it might bring some racy situations while
+ * performing balloon page compaction. In order to sort out these racy scenarios
+ * and safely perform balloon's page compaction and migration we must, always,
+ * ensure following these three simple rules:
+ *
+ *   i. when updating a balloon's page ->mapping element, strictly do it under
+ *      the following lock order, independently of the far superior
+ *      locking scheme (lru_lock, balloon_lock):
+ *	    +-page_lock(page);
+ *	      +--spin_lock_irq(&b_dev_info->pages_lock);
+ *	            ... page->mapping updates here ...
+ *
+ *  ii. before isolating or dequeueing a balloon page from the balloon device
+ *      pages list, the page reference counter must be raised by one and the
+ *      extra refcount must be dropped when the page is enqueued back into
+ *      the balloon device page list, thus a balloon page keeps its reference
+ *      counter raised only while it is under our special handling;
+ *
+ * iii. after the lockless scan step have selected a potential balloon page for
+ *      isolation, re-test the PageBalloon mark and the PagePrivate flag
+ *      under the proper page lock, to ensure isolating a valid balloon page
+ *      (not yet isolated, nor under release procedure)
+ *
+ *  iv. isolation or dequeueing procedure must clear PagePrivate flag under
+ *      page lock together with removing page from balloon device page list.
+ *
+ * The functions provided by this interface are placed to help on coping with
+ * the aforementioned balloon page corner case, as well as to ensure the simple
+ * set of exposed rules are satisfied while we are dealing with balloon pages
+ * compaction / migration.

+ * DOC: B+Tree basics
+ *
+ * A B+Tree is a data structure for looking up arbitrary (currently allowing
+ * unsigned long, u32, u64 and 2 * u64) keys into pointers. The data structure
+ * is described at http://en.wikipedia.org/wiki/B-tree, we currently do not
+ * use binary search to find the key on lookups.
+ *
+ * Each B+Tree consists of a head, that contains bookkeeping information and
+ * a variable number (starting with zero) nodes. Each node contains the keys
+ * and pointers to sub-nodes, or, for leaf nodes, the keys and values for the
+ * tree entries.
+ *
+ * Each node in this implementation has the following layout:
+ * [key1, key2, ..., keyN] [val1, val2, ..., valN]
+ *
+ * Each key here is an array of unsigned longs, geo->no_longs in total. The
+ * number of keys and values (N) is geo->no_pairs.

+ *
+ * - Mount options "noprefix", "xattr", "clone_children", "release_agent"
+ *   and "name" are disallowed.
+ *
+ * - When mounting an existing superblock, mount options should match.
+ *
+ * - Remount is disallowed.
+ *
+ * - rename(2) is disallowed.
+ *
+ * - "tasks" is removed.  Everything should be at process granularity.  Use
+ *   "cgroup.procs" instead.
+ *
+ * - "cgroup.procs" is not sorted.  pids will be unique unless they got
+ *   recycled inbetween reads.
+ *
+ * - "release_agent" and "notify_on_release" are removed.  Replacement
+ *   notification mechanism will be implemented.
+ *
+ * - "cgroup.clone_children" is removed.
+ *
+ * - "cgroup.subtree_populated" is available.  Its value is 0 if the cgroup
+ *   and its descendants contain no task; otherwise, 1.  The file also
+ *   generates kernfs notification which can be monitored through poll and
+ *   [di]notify when the value of the file changes.
+ *
+ * - cpuset: tasks will be kept in empty cpusets when hotplug happens and
+ *   take masks of ancestors with non-empty cpus/mems, instead of being
+ *   moved to an ancestor.
+ *
+ * - cpuset: a task can be moved into an empty cpuset, and again it takes
+ *   masks of ancestors.
+ *
+ * - memcg: use_hierarchy is on by default and the cgroup file for the flag
+ *   is not created.

+/**
+ * struct clk_ops -  Callback operations for hardware clocks; these are to
+ * be provided by the clock implementation, and will be called by drivers
+ * through the clk_* api.
+ *
+ * @prepare:	Prepare the clock for enabling. This must not return until
+ *		the clock is fully prepared, and it's safe to call clk_enable.
+ *		This callback is intended to allow clock implementations to
+ *		do any initialisation that may sleep. Called with
+ *		prepare_lock held.
+ *
+ * @unprepare:	Release the clock from its prepared state. This will typically
+ *		undo any work done in the @prepare callback. Called with
+ *		prepare_lock held.
+ *
+ * @is_prepared: Queries the hardware to determine if the clock is prepared.
+ *		This function is allowed to sleep. Optional, if this op is not
+ *		set then the prepare count will be used.
+ *
+ * @unprepare_unused: Unprepare the clock atomically.  Only called from
+ *		clk_disable_unused for prepare clocks with special needs.
+ *		Called with prepare mutex held. This function may sleep.
+ *
+ * @enable:	Enable the clock atomically. This must not return until the
+ *		clock is generating a valid clock signal, usable by consumer
+ *		devices. Called with enable_lock held. This function must not
+ *		sleep.
+ *
+ * @disable:	Disable the clock atomically. Called with enable_lock held.
+ *		This function must not sleep.
+ *
+ * @is_enabled:	Queries the hardware to determine if the clock is enabled.
+ *		This function must not sleep. Optional, if this op is not
+ *		set then the enable count will be used.
+ *
+ * @disable_unused: Disable the clock atomically.  Only called from
+ *		clk_disable_unused for gate clocks with special needs.
+ *		Called with enable_lock held.  This function must not
+ *		sleep.
+ *
+ * @recalc_rate	Recalculate the rate of this clock, by querying hardware. The
+ *		parent rate is an input parameter.  It is up to the caller to
+ *		ensure that the prepare_mutex is held across this call.
+ *		Returns the calculated rate.  Optional, but recommended - if
+ *		this op is not set then clock rate will be initialized to 0.
+ *
+ * @round_rate:	Given a target rate as input, returns the closest rate actually
+ *		supported by the clock. The parent rate is an input/output
+ *		parameter.
+ *
+ * @determine_rate: Given a target rate as input, returns the closest rate
+ *		actually supported by the clock, and optionally the parent clock
+ *		that should be used to provide the clock rate.
+ *
+ * @set_parent:	Change the input source of this clock; for clocks with multiple
+ *		possible parents specify a new parent by passing in the index
+ *		as a u8 corresponding to the parent in either the .parent_names
+ *		or .parents arrays.  This function in affect translates an
+ *		array index into the value programmed into the hardware.
+ *		Returns 0 on success, -EERROR otherwise.
+ *
+ * @get_parent:	Queries the hardware to determine the parent of a clock.  The
+ *		return value is a u8 which specifies the index corresponding to
+ *		the parent clock.  This index can be applied to either the
+ *		.parent_names or .parents arrays.  In short, this function
+ *		translates the parent value read from hardware into an array
+ *		index.  Currently only called when the clock is initialized by
+ *		__clk_init.  This callback is mandatory for clocks with
+ *		multiple parents.  It is optional (and unnecessary) for clocks
+ *		with 0 or 1 parents.
+ *
+ * @set_rate:	Change the rate of this clock. The requested rate is specified
+ *		by the second argument, which should typically be the return
+ *		of .round_rate call.  The third argument gives the parent rate
+ *		which is likely helpful for most .set_rate implementation.
+ *		Returns 0 on success, -EERROR otherwise.
+ *
+ * @set_rate_and_parent: Change the rate and the parent of this clock. The
+ *		requested rate is specified by the second argument, which
+ *		should typically be the return of .round_rate call.  The
+ *		third argument gives the parent rate which is likely helpful
+ *		for most .set_rate_and_parent implementation. The fourth
+ *		argument gives the parent index. This callback is optional (and
+ *		unnecessary) for clocks with 0 or 1 parents as well as
+ *		for clocks that can tolerate switching the rate and the parent
+ *		separately via calls to .set_parent and .set_rate.
+ *		Returns 0 on success, -EERROR otherwise.
+ *
+ * @recalc_accuracy: Recalculate the accuracy of this clock. The clock accuracy
+ *		is expressed in ppb (parts per billion). The parent accuracy is
+ *		an input parameter.
+ *		Returns the calculated accuracy.  Optional - if	this op is not
+ *		set then clock accuracy will be initialized to parent accuracy
+ *		or 0 (perfect clock) if clock has no parent.
+ *
+ * @get_phase:	Queries the hardware to get the current phase of a clock.
+ *		Returned values are 0-359 degrees on success, negative
+ *		error codes on failure.
+ *
+ * @set_phase:	Shift the phase this clock signal in degrees specified
+ *		by the second argument. Valid values for degrees are
+ *		0-359. Return 0 on success, otherwise -EERROR.
+ *
+ * @init:	Perform platform-specific initialization magic.
+ *		This is not not used by any of the basic clock types.
+ *		Please consider other ways of solving initialization problems
+ *		before using this callback, as its use is discouraged.
+ *
+ * @debug_init:	Set up type-specific debugfs entries for this clock.  This
+ *		is called once, after the debugfs directory entry for this
+ *		clock has been created.  The dentry pointer representing that
+ *		directory is provided as an argument.  Called with
+ *		prepare_lock held.  Returns 0 on success, -EERROR otherwise.
+ *
+ *
+ * The clk_enable/clk_disable and clk_prepare/clk_unprepare pairs allow
+ * implementations to split any work between atomic (enable) and sleepable
+ * (prepare) contexts.  If enabling a clock requires code that might sleep,
+ * this must be done in clk_prepare.  Clock enable code that will never be
+ * called in a sleepable context may be implemented in clk_enable.
+ *
+ * Typically, drivers will call clk_prepare when a clock may be needed later
+ * (eg. when a device is opened), and clk_enable when the clock is actually
+ * required (eg. from an interrupt). Note that clk_prepare MUST have been
+ * called before clk_enable.

+ * ENABLE_ON_INIT: Clock is enabled on init.
+ * INVERT_ENABLE: By default, clock enable bit behavior is '1' enable, '0'

+ * CLOCK_CLKOUTX2: (OMAP4 only) DPLL CLKOUT and CLKOUTX2 GATE_CTRL
+ *     bits share the same register.  This flag allows the
+ *     omap4_dpllmx*() code to determine which GATE_CTRL bit field
+ *     should be used.  This is a temporary solution - a better approach
+ *     would be to associate clock type-specific data with the clock,
+ *     similar to the struct dpll_data approach.

+/**
+ * cnt32_to_63 - Expand a 32-bit counter to a 63-bit counter
+ * @cnt_lo: The low part of the counter
+ *
+ * Many hardware clock counters are only 32 bits wide and therefore have
+ * a relatively short period making wrap-arounds rather frequent.  This
+ * is a problem when implementing sched_clock() for example, where a 64-bit
+ * non-wrapping monotonic value is expected to be returned.
+ *
+ * To overcome that limitation, let's extend a 32-bit counter to 63 bits
+ * in a completely lock free fashion. Bits 0 to 31 of the clock are provided
+ * by the hardware while bits 32 to 62 are stored in memory.  The top bit in
+ * memory is used to synchronize with the hardware clock half-period.  When
+ * the top bit of both counters (hardware and in memory) differ then the
+ * memory is updated with a new value, incrementing it when the hardware
+ * counter wraps around.
+ *
+ * Because a word store in memory is atomic then the incremented value will
+ * always be in synch with the top bit indicating to any potential concurrent
+ * reader if the value in memory is up to date or not with regards to the
+ * needed increment.  And any race in updating the value in memory is harmless
+ * as the same value would simply be stored more than once.
+ *
+ * The restrictions for the algorithm to work properly are:
+ *
+ * 1) this code must be called at least once per each half period of the
+ *    32-bit counter;
+ *
+ * 2) this code must not be preempted for a duration longer than the
+ *    32-bit counter half period minus the longest period between two
+ *    calls to this code;
+ *
+ * Those requirements ensure proper update to the state bit in memory.
+ * This is usually not a problem in practice, but if it is then a kernel
+ * timer should be scheduled to manage for this code to be executed often
+ * enough.
+ *
+ * And finally:
+ *
+ * 3) the cnt_lo argument must be seen as a globally incrementing value,
+ *    meaning that it should be a direct reference to the counter data which
+ *    can be evaluated according to a specific ordering within the macro,
+ *    and not the result of a previous evaluation stored in a variable.
+ *
+ * For example, this is wrong:
+ *
+ *	u32 partial = get_hw_count();
+ *	u64 full = cnt32_to_63(partial);
+ *	return full;
+ *
+ * This is fine:
+ *
+ *	u64 full = cnt32_to_63(get_hw_count());
+ *	return full;
+ *
+ * Note that the top bit (bit 63) in the returned value should be considered
+ * as garbage.  It is not cleared here because callers are likely to use a
+ * multiplier on the returned value which can get rid of the top bit
+ * implicitly by making the multiplier even, therefore saving on a runtime
+ * clear-bit instruction. Otherwise caller must remember to clear the top
+ * bit explicitly.

+/**
+ * struct crypto_alg - definition of a cryptograpic cipher algorithm
+ * @cra_flags: Flags describing this transformation. See include/linux/crypto.h
+ *	       CRYPTO_ALG_* flags for the flags which go in here. Those are
+ *	       used for fine-tuning the description of the transformation
+ *	       algorithm.
+ * @cra_blocksize: Minimum block size of this transformation. The size in bytes
+ *		   of the smallest possible unit which can be transformed with
+ *		   this algorithm. The users must respect this value.
+ *		   In case of HASH transformation, it is possible for a smaller
+ *		   block than @cra_blocksize to be passed to the crypto API for
+ *		   transformation, in case of any other transformation type, an
+ * 		   error will be returned upon any attempt to transform smaller
+ *		   than @cra_blocksize chunks.
+ * @cra_ctxsize: Size of the operational context of the transformation. This
+ *		 value informs the kernel crypto API about the memory size
+ *		 needed to be allocated for the transformation context.
+ * @cra_alignmask: Alignment mask for the input and output data buffer. The data
+ *		   buffer containing the input data for the algorithm must be
+ *		   aligned to this alignment mask. The data buffer for the
+ *		   output data must be aligned to this alignment mask. Note that
+ *		   the Crypto API will do the re-alignment in software, but
+ *		   only under special conditions and there is a performance hit.
+ *		   The re-alignment happens at these occasions for different
+ *		   @cra_u types: cipher -- For both input data and output data
+ *		   buffer; ahash -- For output hash destination buf; shash --
+ *		   For output hash destination buf.
+ *		   This is needed on hardware which is flawed by design and
+ *		   cannot pick data from arbitrary addresses.
+ * @cra_priority: Priority of this transformation implementation. In case
+ *		  multiple transformations with same @cra_name are available to
+ *		  the Crypto API, the kernel will use the one with highest
+ *		  @cra_priority.
+ * @cra_name: Generic name (usable by multiple implementations) of the
+ *	      transformation algorithm. This is the name of the transformation
+ *	      itself. This field is used by the kernel when looking up the
+ *	      providers of particular transformation.
+ * @cra_driver_name: Unique name of the transformation provider. This is the
+ *		     name of the provider of the transformation. This can be any
+ *		     arbitrary value, but in the usual case, this contains the
+ *		     name of the chip or provider and the name of the
+ *		     transformation algorithm.
+ * @cra_type: Type of the cryptographic transformation. This is a pointer to
+ *	      struct crypto_type, which implements callbacks common for all
+ *	      trasnformation types. There are multiple options:
+ *	      &crypto_blkcipher_type, &crypto_ablkcipher_type,
+ *	      &crypto_ahash_type, &crypto_aead_type, &crypto_rng_type.
+ *	      This field might be empty. In that case, there are no common
+ *	      callbacks. This is the case for: cipher, compress, shash.
+ * @cra_u: Callbacks implementing the transformation. This is a union of
+ *	   multiple structures. Depending on the type of transformation selected
+ *	   by @cra_type and @cra_flags above, the associated structure must be
+ *	   filled with callbacks. This field might be empty. This is the case
+ *	   for ahash, shash.
+ * @cra_init: Initialize the cryptographic transformation object. This function
+ *	      is used to initialize the cryptographic transformation object.
+ *	      This function is called only once at the instantiation time, right
+ *	      after the transformation context was allocated. In case the
+ *	      cryptographic hardware has some special requirements which need to
+ *	      be handled by software, this function shall check for the precise
+ *	      requirement of the transformation and put any software fallbacks
+ *	      in place.
+ * @cra_exit: Deinitialize the cryptographic transformation object. This is a
+ *	      counterpart to @cra_init, used to remove various changes set in
+ *	      @cra_init.
+ * @cra_module: Owner of this transformation implementation. Set to THIS_MODULE
+ * @cra_list: internally used
+ * @cra_users: internally used
+ * @cra_refcnt: internally used
+ * @cra_destroy: internally used
+ *
+ * The struct crypto_alg describes a generic Crypto API algorithm and is common
+ * for all of the transformations. Any variable not documented here shall not
+ * be used by a cipher implementation as it is internal to the Crypto API.

+ * DOC: Asynchronous Block Cipher API
+ *
+ * Asynchronous block cipher API is used with the ciphers of type
+ * CRYPTO_ALG_TYPE_ABLKCIPHER (listed as type "ablkcipher" in /proc/crypto).
+ *
+ * Asynchronous cipher operations imply that the function invocation for a
+ * cipher request returns immediately before the completion of the operation.
+ * The cipher request is scheduled as a separate kernel thread and therefore
+ * load-balanced on the different CPUs via the process scheduler. To allow
+ * the kernel crypto API to inform the caller about the completion of a cipher
+ * request, the caller must provide a callback function. That function is
+ * invoked with the cipher handle when the request completes.
+ *
+ * To support the asynchronous operation, additional information than just the
+ * cipher handle must be supplied to the kernel crypto API. That additional
+ * information is given by filling in the ablkcipher_request data structure.
+ *
+ * For the asynchronous block cipher API, the state is maintained with the tfm
+ * cipher handle. A single tfm can be used across multiple calls and in
+ * parallel. For asynchronous block cipher calls, context data supplied and
+ * only used by the caller can be referenced the request data structure in
+ * addition to the IV used for the cipher request. The maintenance of such
+ * state information would be important for a crypto driver implementer to
+ * have, because when calling the callback function upon completion of the
+ * cipher operation, that callback function may need some information about
+ * which operation just finished if it invoked multiple in parallel. This
+ * state information is unused by the kernel crypto API.

+ * data memory is filled during the encryption operation. For decryption, the

+ * @drv_groups: Default attributes of the device drivers on the bus.
+ * @match:	Called, perhaps multiple times, whenever a new device or driver
+ *		is added for this bus. It should return a nonzero value if the
+ *		given device can be handled by the given driver.
+ * @uevent:	Called when a device is added, removed, or a few other things
+ *		that generate uevents to add the environment variables.
+ * @probe:	Called when a new device or driver add to this bus, and callback
+ *		the specific driver's probe to initial the matched device.
+ * @remove:	Called when a device removed from this bus.
+ * @shutdown:	Called at shut-down time to quiesce the device.
+ *
+ * @online:	Called to put the device back online (after offlining it).
+ * @offline:	Called to put the device offline for hot-removal. May fail.
+ *
+ * @suspend:	Called when a device on this bus wants to go to sleep mode.
+ * @resume:	Called to bring a device on this bus out of sleep mode.
+ * @pm:		Power management operations of this bus, callback the specific

+/**
+ * struct device - The basic device structure
+ * @parent:	The device's "parent" device, the device to which it is attached.
+ * 		In most cases, a parent device is some sort of bus or host
+ * 		controller. If parent is NULL, the device, is a top-level device,
+ * 		which is not usually what you want.
+ * @p:		Holds the private data of the driver core portions of the device.
+ * 		See the comment of the struct device_private for detail.
+ * @kobj:	A top-level, abstract class from which other classes are derived.
+ * @init_name:	Initial name of the device.
+ * @type:	The type of device.
+ * 		This identifies the device type and carries type-specific
+ * 		information.
+ * @mutex:	Mutex to synchronize calls to its driver.
+ * @bus:	Type of bus device is on.
+ * @driver:	Which driver has allocated this
+ * @platform_data: Platform data specific to the device.
+ * 		Example: For devices on custom boards, as typical of embedded
+ * 		and SOC based hardware, Linux often uses platform_data to point
+ * 		to board-specific structures describing devices and how they
+ * 		are wired.  That can include what ports are available, chip
+ * 		variants, which GPIO pins act in what additional roles, and so
+ * 		on.  This shrinks the "Board Support Packages" (BSPs) and
+ * 		minimizes board-specific #ifdefs in drivers.
+ * @driver_data: Private pointer for driver specific info.
+ * @power:	For device power management.
+ * 		See Documentation/power/devices.txt for details.
+ * @pm_domain:	Provide callbacks that are executed during system suspend,
+ * 		hibernation, system resume and during runtime PM transitions
+ * 		along with subsystem-level and driver-level callbacks.
+ * @pins:	For device pin management.
+ *		See Documentation/pinctrl.txt for details.
+ * @numa_node:	NUMA node this device is close to.
+ * @dma_mask:	Dma mask (if dma'ble device).
+ * @coherent_dma_mask: Like dma_mask, but for alloc_coherent mapping as not all
+ * 		hardware supports 64-bit addresses for consistent allocations
+ * 		such descriptors.
+ * @dma_pfn_offset: offset of DMA memory range relatively of RAM
+ * @dma_parms:	A low level driver may set these to teach IOMMU code about
+ * 		segment limitations.
+ * @dma_pools:	Dma pools (if dma'ble device).
+ * @dma_mem:	Internal for coherent mem override.
+ * @cma_area:	Contiguous memory area for dma allocations
+ * @archdata:	For arch-specific additions.
+ * @of_node:	Associated device tree node.
+ * @fwnode:	Associated device node supplied by platform firmware.
+ * @devt:	For creating the sysfs "dev".
+ * @id:		device instance
+ * @devres_lock: Spinlock to protect the resource of the device.
+ * @devres_head: The resources list of the device.
+ * @knode_class: The node used to add the device to the class list.
+ * @class:	The class of the device.
+ * @groups:	Optional attribute groups.
+ * @release:	Callback to free the device after all references have
+ * 		gone away. This should be set by the allocator of the
+ * 		device (i.e. the bus driver that discovered the device).
+ * @iommu_group: IOMMU group the device belongs to.
+ *
+ * @offline_disabled: If set, the device is permanently online.
+ * @offline:	Set after successful invocation of bus type's .offline().
+ *
+ * At the lowest level, every device in a Linux system is represented by an
+ * instance of struct device. The device structure contains the information
+ * that the device model core needs to model the system. Most subsystems,
+ * however, track additional information about the devices they host. As a
+ * result, it is rare for devices to be represented by bare device structures;
+ * instead, that structure, like kobject structures, is usually embedded within
+ * a higher-level representation of the device.

+ * Contiguous Memory Allocator
+ *
+ *   The Contiguous Memory Allocator (CMA) makes it possible to
+ *   allocate big contiguous chunks of memory after the system has
+ *   booted.
+ *
+ * Why is it needed?
+ *
+ *   Various devices on embedded systems have no scatter-getter and/or
+ *   IO map support and require contiguous blocks of memory to
+ *   operate.  They include devices such as cameras, hardware video
+ *   coders, etc.
+ *
+ *   Such devices often require big memory buffers (a full HD frame
+ *   is, for instance, more then 2 mega pixels large, i.e. more than 6
+ *   MB of memory), which makes mechanisms such as kmalloc() or
+ *   alloc_page() ineffective.
+ *
+ *   At the same time, a solution where a big memory region is
+ *   reserved for a device is suboptimal since often more memory is
+ *   reserved then strictly required and, moreover, the memory is
+ *   inaccessible to page system even if device drivers don't use it.
+ *
+ *   CMA tries to solve this issue by operating on memory regions
+ *   where only movable pages can be allocated from.  This way, kernel
+ *   can use the memory for pagecache and when device driver requests
+ *   it, allocated pages can be migrated.
+ *
+ * Driver usage
+ *
+ *   CMA should not be used by the device drivers directly. It is
+ *   only a helper framework for dma-mapping subsystem.
+ *
+ *   For more information, see kernel-docs in drivers/base/dma-contiguous.c

+ * The tag number of any field (regardless of containing struct)

+ *
+ * The tag numbers themselves are per struct, though,
+ * so should always begin at 1 (not 0, that is the special "NLA_UNSPEC" type,
+ * which we won't use here).

+ * Dynamic queue limits (dql) - Definitions
+ *
+ * Copyright (c) 2011, Tom Herbert <therbert@google.com>
+ *
+ * This header file contains the definitions for dynamic queue limits (dql).
+ * dql would be used in conjunction with a producer/consumer type queue
+ * (possibly a HW queue).  Such a queue would have these general properties:
+ *
+ *   1) Objects are queued up to some limit specified as number of objects.
+ *   2) Periodically a completion process executes which retires consumed
+ *      objects.
+ *   3) Starvation occurs when limit has been reached, all queued data has
+ *      actually been consumed, but completion processing has not yet run
+ *      so queuing new data is blocked.
+ *   4) Minimizing the amount of queued data is desirable.
+ *
+ * The goal of dql is to calculate the limit as the minimum number of objects
+ * needed to prevent starvation.
+ *
+ * The primary functions of dql are:
+ *    dql_queued - called when objects are enqueued to record number of objects
+ *    dql_avail - returns how many objects are available to be queued based
+ *      on the object limit and how many objects are already enqueued
+ *    dql_completed - called at completion time to indicate how many objects
+ *      were retired from the queue
+ *
+ * The dql implementation does not implement any locking for the dql data
+ * structures, the higher layer should provide this.  dql_queued should
+ * be serialized to prevent concurrent execution of the function; this
+ * is also true for  dql_completed.  However, dql_queued and dlq_completed  can
+ * be executed concurrently (i.e. they can be protected by different locks).

+ * Concepts used at the EDAC subsystem
+ *
+ * There are several things to be aware of that aren't at all obvious:
+ *
+ * SOCKETS, SOCKET SETS, BANKS, ROWS, CHIP-SELECT ROWS, CHANNELS, etc..
+ *
+ * These are some of the many terms that are thrown about that don't always
+ * mean what people think they mean (Inconceivable!).  In the interest of
+ * creating a common ground for discussion, terms and their definitions
+ * will be established.
+ *
+ * Memory devices:	The individual DRAM chips on a memory stick.  These
+ *			devices commonly output 4 and 8 bits each (x4, x8).
+ *			Grouping several of these in parallel provides the
+ *			number of bits that the memory controller expects:
+ *			typically 72 bits, in order to provide 64 bits +
+ *			8 bits of ECC data.
+ *
+ * Memory Stick:	A printed circuit board that aggregates multiple
+ *			memory devices in parallel.  In general, this is the
+ *			Field Replaceable Unit (FRU) which gets replaced, in
+ *			the case of excessive errors. Most often it is also
+ *			called DIMM (Dual Inline Memory Module).
+ *
+ * Memory Socket:	A physical connector on the motherboard that accepts
+ *			a single memory stick. Also called as "slot" on several
+ *			datasheets.
+ *
+ * Channel:		A memory controller channel, responsible to communicate
+ *			with a group of DIMMs. Each channel has its own
+ *			independent control (command) and data bus, and can
+ *			be used independently or grouped with other channels.
+ *
+ * Branch:		It is typically the highest hierarchy on a
+ *			Fully-Buffered DIMM memory controller.
+ *			Typically, it contains two channels.
+ *			Two channels at the same branch can be used in single
+ *			mode or in lockstep mode.
+ *			When lockstep is enabled, the cacheline is doubled,
+ *			but it generally brings some performance penalty.
+ *			Also, it is generally not possible to point to just one
+ *			memory stick when an error occurs, as the error
+ *			correction code is calculated using two DIMMs instead
+ *			of one. Due to that, it is capable of correcting more
+ *			errors than on single mode.
+ *
+ * Single-channel:	The data accessed by the memory controller is contained
+ *			into one dimm only. E. g. if the data is 64 bits-wide,
+ *			the data flows to the CPU using one 64 bits parallel
+ *			access.
+ *			Typically used with SDR, DDR, DDR2 and DDR3 memories.
+ *			FB-DIMM and RAMBUS use a different concept for channel,
+ *			so this concept doesn't apply there.
+ *
+ * Double-channel:	The data size accessed by the memory controller is
+ *			interlaced into two dimms, accessed at the same time.
+ *			E. g. if the DIMM is 64 bits-wide (72 bits with ECC),
+ *			the data flows to the CPU using a 128 bits parallel
+ *			access.
+ *
+ * Chip-select row:	This is the name of the DRAM signal used to select the
+ *			DRAM ranks to be accessed. Common chip-select rows for
+ *			single channel are 64 bits, for dual channel 128 bits.
+ *			It may not be visible by the memory controller, as some
+ *			DIMM types have a memory buffer that can hide direct
+ *			access to it from the Memory Controller.
+ *
+ * Single-Ranked stick:	A Single-ranked stick has 1 chip-select row of memory.
+ *			Motherboards commonly drive two chip-select pins to
+ *			a memory stick. A single-ranked stick, will occupy
+ *			only one of those rows. The other will be unused.
+ *
+ * Double-Ranked stick:	A double-ranked stick has two chip-select rows which
+ *			access different sets of memory devices.  The two
+ *			rows cannot be accessed concurrently.
+ *
+ * Double-sided stick:	DEPRECATED TERM, see Double-Ranked stick.
+ *			A double-sided stick has two chip-select rows which
+ *			access different sets of memory devices. The two
+ *			rows cannot be accessed concurrently. "Double-sided"
+ *			is irrespective of the memory devices being mounted
+ *			on both sides of the memory stick.
+ *
+ * Socket set:		All of the memory sticks that are required for
+ *			a single memory access or all of the memory sticks
+ *			spanned by a chip-select row.  A single socket set
+ *			has two chip-select rows and if double-sided sticks
+ *			are used these will occupy those chip-select rows.
+ *
+ * Bank:		This term is avoided because it is unclear when
+ *			needing to distinguish between chip-select rows and
+ *			socket sets.
+ *
+ * Controller pages:
+ *
+ * Physical pages:
+ *
+ * Virtual pages:
+ *

+ *	zero.
+ * @set_settings: Set various device settings including Ethernet link
+ *	settings.  Returns a negative error code or zero.
+ * @get_drvinfo: Report driver/device information.  Should only set the
+ *	@driver, @version, @fw_version and @bus_info fields.  If not
+ *	implemented, the @driver and @bus_info fields will be filled in
+ *	according to the netdev's parent device.
+ * @get_regs_len: Get buffer length required for @get_regs
+ * @get_regs: Get device registers
+ * @get_wol: Report whether Wake-on-Lan is enabled
+ * @set_wol: Turn Wake-on-Lan on or off.  Returns a negative error code
+ *	or zero.
+ * @get_msglevel: Report driver message level.  This should be the value
+ *	of the @msg_enable field used by netif logging functions.
+ * @set_msglevel: Set driver message level
+ * @nway_reset: Restart autonegotiation.  Returns a negative error code
+ *	or zero.
+ * @get_link: Report whether physical link is up.  Will only be called if
+ *	the netdev is up.  Should usually be set to ethtool_op_get_link(),
+ *	which uses netif_carrier_ok().
+ * @get_eeprom: Read data from the device EEPROM.
+ *	Should fill in the magic field.  Don't need to check len for zero
+ *	or wraparound.  Fill in the data argument with the eeprom values
+ *	from offset to offset + len.  Update len to the amount read.
+ *	Returns an error or zero.
+ * @set_eeprom: Write data to the device EEPROM.
+ *	Should validate the magic field.  Don't need to check len for zero
+ *	or wraparound.  Update len to the amount written.  Returns an error
+ *	or zero.
+ * @get_coalesce: Get interrupt coalescing parameters.  Returns a negative

+ * @get_pauseparam: Report pause parameters
+ * @set_pauseparam: Set pause parameters.  Returns a negative error code
+ *	or zero.
+ * @self_test: Run specified self-tests
+ * @get_strings: Return a set of strings that describe the requested objects
+ * @set_phys_id: Identify the physical devices, e.g. by flashing an LED
+ *	attached to it.  The implementation may update the indicator
+ *	asynchronously or synchronously, but in either case it must return
+ *	quickly.  It is initially called with the argument %ETHTOOL_ID_ACTIVE,
+ *	and must either activate asynchronous updates and return zero, return
+ *	a negative error or return a positive frequency for synchronous
+ *	indication (e.g. 1 for one on/off cycle per second).  If it returns
+ *	a frequency then it will be called again at intervals with the
+ *	argument %ETHTOOL_ID_ON or %ETHTOOL_ID_OFF and should set the state of
+ *	the indicator accordingly.  Finally, it is called with the argument
+ *	%ETHTOOL_ID_INACTIVE and must deactivate the indicator.  Returns a
+ *	negative error code or zero.
+ * @get_ethtool_stats: Return extended statistics about the device.
+ *	This is only useful if the device maintains statistics not
+ *	included in &struct rtnl_link_stats64.
+ * @begin: Function to be called before any other operation.  Returns a
+ *	negative error code or zero.
+ * @complete: Function to be called after any other operation except
+ *	@begin.  Will be called even if the other operation failed.
+ * @get_priv_flags: Report driver-specific feature flags.
+ * @set_priv_flags: Set driver-specific feature flags.  Returns a negative
+ *	error code or zero.
+ * @get_sset_count: Get number of strings that @get_strings will write.
+ * @get_rxnfc: Get RX flow classification rules.  Returns a negative
+ *	error code or zero.
+ * @set_rxnfc: Set RX flow classification rules.  Returns a negative
+ *	error code or zero.
+ * @flash_device: Write a firmware image to device's flash memory.
+ *	Returns a negative error code or zero.
+ * @reset: Reset (part of) the device, as specified by a bitmask of
+ *	flags from &enum ethtool_reset_flags.  Returns a negative
+ *	error code or zero.
+ * @get_rxfh_key_size: Get the size of the RX flow hash key.
+ *	Returns zero if not supported for this specific device.
+ * @get_rxfh_indir_size: Get the size of the RX flow hash indirection table.
+ *	Returns zero if not supported for this specific device.
+ * @get_rxfh: Get the contents of the RX flow hash indirection table, hash key
+ *	and/or hash function.
+ *	Returns a negative error code or zero.
+ * @set_rxfh: Set the contents of the RX flow hash indirection table, hash
+ *	key, and/or hash function.  Arguments which are set to %NULL or zero
+ *	will remain unchanged.
+ *	Returns a negative error code or zero. An error code must be returned
+ *	if at least one unsupported change was requested.
+ * @get_channels: Get number of channels.
+ * @set_channels: Set number of channels.  Returns a negative error code or
+ *	zero.
+ * @get_dump_flag: Get dump flag indicating current dump length, version,
+ * 		   and flag of the device.
+ * @get_dump_data: Get dump data.
+ * @set_dump: Set dump specific flags to the device.
+ * @get_ts_info: Get the time stamping and PTP hardware clock capabilities.
+ *	Drivers supporting transmit time stamps in software should set this to
+ *	ethtool_op_get_ts_info().
+ * @get_module_info: Get the size and type of the eeprom contained within
+ *	a plug-in module.
+ * @get_module_eeprom: Get the eeprom information from the plug-in module
+ * @get_eee: Get Energy-Efficient (EEE) supported and status.
+ * @set_eee: Set EEE status (enable/disable) as well as LPI timers.
+ *
+ * All operations are optional (i.e. the function pointer may be set
+ * to %NULL) and callers must take this into account.  Callers must
+ * hold the RTNL lock.
+ *
+ * See the structures used by these operations for further documentation.

+ * struct export_operations - for nfsd to communicate with file systems
+ * @encode_fh:      encode a file handle fragment from a dentry
+ * @fh_to_dentry:   find the implied object and get a dentry for it
+ * @fh_to_parent:   find the implied object's parent and get a dentry for it
+ * @get_name:       find the name for a given inode in a given directory
+ * @get_parent:     find the parent of a given directory
+ * @commit_metadata: commit metadata changes to stable storage
+ *
+ * See Documentation/filesystems/nfs/Exporting for details on how to use
+ * this interface correctly.
+ *
+ * encode_fh:
+ *    @encode_fh should store in the file handle fragment @fh (using at most
+ *    @max_len bytes) information that can be used by @decode_fh to recover the
+ *    file referred to by the &struct dentry @de.  If the @connectable flag is
+ *    set, the encode_fh() should store sufficient information so that a good
+ *    attempt can be made to find not only the file but also it's place in the
+ *    filesystem.   This typically means storing a reference to de->d_parent in
+ *    the filehandle fragment.  encode_fh() should return the fileid_type on
+ *    success and on error returns 255 (if the space needed to encode fh is
+ *    greater than @max_len*4 bytes). On error @max_len contains the minimum
+ *    size(in 4 byte unit) needed to encode the file handle.
+ *
+ * fh_to_dentry:
+ *    @fh_to_dentry is given a &struct super_block (@sb) and a file handle
+ *    fragment (@fh, @fh_len). It should return a &struct dentry which refers
+ *    to the same file that the file handle fragment refers to.  If it cannot,
+ *    it should return a %NULL pointer if the file was found but no acceptable
+ *    &dentries were available, or an %ERR_PTR error code indicating why it
+ *    couldn't be found (e.g. %ENOENT or %ENOMEM).  Any suitable dentry can be
+ *    returned including, if necessary, a new dentry created with d_alloc_root.
+ *    The caller can then find any other extant dentries by following the
+ *    d_alias links.
+ *
+ * fh_to_parent:
+ *    Same as @fh_to_dentry, except that it returns a pointer to the parent
+ *    dentry if it was encoded into the filehandle fragment by @encode_fh.
+ *
+ * get_name:
+ *    @get_name should find a name for the given @child in the given @parent
+ *    directory.  The name should be stored in the @name (with the
+ *    understanding that it is already pointing to a a %NAME_MAX+1 sized
+ *    buffer.   get_name() should return %0 on success, a negative error code
+ *    or error.  @get_name will be called without @parent->i_mutex held.
+ *
+ * get_parent:
+ *    @get_parent should find the parent directory for the given @child which
+ *    is also a directory.  In the event that it cannot be found, or storage
+ *    space cannot be allocated, a %ERR_PTR should be returned.
+ *
+ * commit_metadata:
+ *    @commit_metadata should commit metadata changes to stable storage.
+ *
+ * Locking rules:
+ *    get_parent is called with child->d_inode->i_mutex down
+ *    get_name is not (which is possibly inconsistent)

+ * implementation know that there is another driver waiting on
+ * the signal (ie. hw->sw case).

+ * This function can be called called from atomic context, but not
+ * from irq context, so normal spinlocks can be used.
+ *
+ * A return value of false indicates the fence already passed,
+ * or some failure occurred that made it impossible to enable
+ * signaling. True indicates successful enabling.
+ *
+ * fence->status may be set in enable_signaling, but only when false is
+ * returned.
+ *
+ * Calling fence_signal before enable_signaling is called allows
+ * for a tiny race window in which enable_signaling is called during,
+ * before, or after fence_signal. To fight this, it is recommended
+ * that before enable_signaling returns true an extra reference is
+ * taken on the fence, to be released when the fence is signaled.
+ * This will mean fence_signal will still be called twice, but
+ * the second time will be a noop since it was already signaled.
+ *
+ * Notes on signaled:
+ * May set fence->status if returning true.
+ *
+ * Notes on wait:
+ * Must not be NULL, set to fence_default_wait for default implementation.
+ * the fence_default_wait implementation should work for any fence, as long
+ * as enable_signaling works correctly.
+ *
+ * Must return -ERESTARTSYS if the wait is intr = true and the wait was
+ * interrupted, and remaining jiffies if fence has signaled, or 0 if wait
+ * timed out. Can also return other error values on custom implementations,
+ * which should be treated as if the fence is signaled. For example a hardware
+ * lockup could be reported like that.
+ *
+ * Notes on release:
+ * Can be NULL, this function allows additional commands to run on
+ * destruction of the fence. Can be called from irq context.
+ * If pointer is set to NULL, kfree will get called instead.

+ * The below are the various read and write types that we support. Some of

+ *
+ *	The block layer uses device plugging to defer IO a little bit, in
+ *	the hope that we will see more IO very shortly. This increases
+ *	coalescing of adjacent IO and thus reduces the number of IOs we
+ *	have to send to the device. It also allows for better queuing,
+ *	if the IO isn't mergeable. If the caller is going to be waiting
+ *	for the IO, then he must ensure that the device is unplugged so
+ *	that the IO is dispatched to the driver.
+ *
+ *	All IO is handled async in Linux. This is fine for background
+ *	writes, but for reads or writes that someone waits for completion
+ *	on, we want to notify the block layer and IO scheduler so that they
+ *	know about it. That allows them to make better scheduling
+ *	decisions. So when the below references 'sync' and 'async', it
+ *	is referencing this priority hint.
+ *
+ * With that in mind, the available types are:
+ *
+ * READ			A normal read operation. Device will be plugged.
+ * READ_SYNC		A synchronous read. Device is not plugged, caller can
+ *			immediately wait on this read without caring about
+ *			unplugging.
+ * READA		Used for read-ahead operations. Lower priority, and the
+ *			block layer could (in theory) choose to ignore this
+ *			request if it runs into resource problems.
+ * WRITE		A normal async write. Device will be plugged.
+ * WRITE_SYNC		Synchronous write. Identical to WRITE, but passes down
+ *			the hint that someone will be waiting on this IO
+ *			shortly. The write equivalent of READ_SYNC.
+ * WRITE_ODIRECT	Special case write for O_DIRECT only.
+ * WRITE_FLUSH		Like WRITE_SYNC but with preceding cache flush.
+ * WRITE_FUA		Like WRITE_SYNC but data is guaranteed to be on
+ *			non-volatile media on completion.
+ * WRITE_FLUSH_FUA	Combination of WRITE_FLUSH and FUA. The IO is preceded
+ *			by a cache flush and data is guaranteed to be on
+ *			non-volatile media on completion.

+ * Inode state bits.  Protected by inode->i_lock
+ *
+ * Three bits determine the dirty state of the inode, I_DIRTY_SYNC,
+ * I_DIRTY_DATASYNC and I_DIRTY_PAGES.
+ *
+ * Four bits define the lifetime of an inode.  Initially, inodes are I_NEW,
+ * until that flag is cleared.  I_WILL_FREE, I_FREEING and I_CLEAR are set at
+ * various stages of removing an inode.
+ *
+ * Two bits are used for locking and completion notification, I_NEW and I_SYNC.
+ *
+ * I_DIRTY_SYNC		Inode is dirty, but doesn't have to be written on
+ *			fdatasync().  i_atime is the usual cause.
+ * I_DIRTY_DATASYNC	Data-related inode changes pending. We keep track of
+ *			these changes separately from I_DIRTY_SYNC so that we
+ *			don't have to write inode on fdatasync() when only
+ *			mtime has changed in it.
+ * I_DIRTY_PAGES	Inode has dirty pages.  Inode itself may be clean.
+ * I_NEW		Serves as both a mutex and completion notification.
+ *			New inodes set I_NEW.  If two processes both create
+ *			the same inode, one of them will release its inode and
+ *			wait for I_NEW to be released before returning.
+ *			Inodes in I_WILL_FREE, I_FREEING or I_CLEAR state can
+ *			also cause waiting on I_NEW, without I_NEW actually
+ *			being set.  find_inode() uses this to prevent returning
+ *			nearly-dead inodes.
+ * I_WILL_FREE		Must be set when calling write_inode_now() if i_count
+ *			is zero.  I_FREEING must be set when I_WILL_FREE is
+ *			cleared.
+ * I_FREEING		Set when inode is about to be freed but still has dirty
+ *			pages or buffers attached or the inode itself is still
+ *			dirty.
+ * I_CLEAR		Added by clear_inode().  In this state the inode is
+ *			clean and can be destroyed.  Inode keeps I_FREEING.
+ *
+ *			Inodes that are I_WILL_FREE, I_FREEING or I_CLEAR are
+ *			prohibited for many purposes.  iget() must wait for
+ *			the inode to be completely released, then create it
+ *			anew.  Other functions will just ignore such inodes,
+ *			if appropriate.  I_NEW is used for waiting.
+ *
+ * I_SYNC		Writeback of inode is running. The bit is set during
+ *			data writeback, and cleared with a wakeup on the bit
+ *			address once it is done. The bit is also used to pin
+ *			the inode in memory for flusher thread.
+ *
+ * I_REFERENCED		Marks the inode as recently references on the LRU list.
+ *
+ * I_DIO_WAKEUP		Never set.  Only used as a key for wait_on_bit().
+ *
+ * Q: What is the difference between I_WILL_FREE and I_FREEING?

+ * Changing those attribute flags after regsitering ftrace_ops will

+ *
+ * ENABLED - set/unset when ftrace_ops is registered/unregistered
+ * DYNAMIC - set when ftrace_ops is registered to denote dynamically
+ *           allocated ftrace_ops which need special care
+ * CONTROL - set manualy by ftrace_ops user to denote the ftrace_ops
+ *           could be controled by following calls:
+ *             ftrace_function_local_enable
+ *             ftrace_function_local_disable
+ * SAVE_REGS - The ftrace_ops wants regs saved at each function called
+ *            and passed to the callback. If this flag is set, but the
+ *            architecture does not support passing regs
+ *            (CONFIG_DYNAMIC_FTRACE_WITH_REGS is not defined), then the
+ *            ftrace_ops will fail to register, unless the next flag
+ *            is set.
+ * SAVE_REGS_IF_SUPPORTED - This is the same as SAVE_REGS, but if the
+ *            handler can handle an arch that does not save regs
+ *            (the handler tests if regs == NULL), then it can set
+ *            this flag instead. It will not fail registering the ftrace_ops
+ *            but, the regs field will be NULL if the arch does not support
+ *            passing regs to the handler.
+ *            Note, if this flag is set, the SAVE_REGS flag will automatically
+ *            get set upon registering the ftrace_ops, if the arch supports it.
+ * RECURSION_SAFE - The ftrace_ops can set this to tell the ftrace infrastructure
+ *            that the call back has its own recursion protection. If it does
+ *            not set this, then the ftrace infrastructure will add recursion
+ *            protection for the caller.
+ * STUB   - The ftrace_ops is just a place holder.
+ * INITIALIZED - The ftrace_ops has already been initialized (first use time
+ *            register_ftrace_function() is called, it will initialized the ops)
+ * DELETED - The ops are being deleted, do not let them be registered again.
+ * ADDING  - The ops is in the process of being added.
+ * REMOVING - The ops is in the process of being removed.
+ * MODIFYING - The ops is in the process of changing its filter functions.
+ * ALLOC_TRAMP - A dynamic trampoline was allocated by the core code.
+ *            The arch specific code sets this flag when it allocated a
+ *            trampoline. This lets the arch know that it can update the
+ *            trampoline in case the callback function changes.
+ *            The ftrace_ops trampoline can be set by the ftrace users, and
+ *            in such cases the arch must not modify it. Only the arch ftrace
+ *            core code should set this flag.
+ * IPMODIFY - The ops can modify the IP register. This can only be set with
+ *            SAVE_REGS. If another ops with this flag set is already registered
+ *            for any of the functions that this ops will be registered for, then
+ *            this ops will fail to register or set_filter_ip.

+ * Basic general purpose allocator for managing special purpose
+ * memory, for example, memory that is not managed by the regular
+ * kmalloc/kfree interface.  Uses for this includes on-device special
+ * memory, uncached memory etc.
+ *
+ * It is safe to use the allocator in NMI handlers and other special
+ * unblockable contexts that could otherwise deadlock on locks.  This
+ * is implemented by using atomic operations and retries on any
+ * conflicts.  The disadvantage is that there may be livelocks in
+ * extreme cases.  For better scalability, one allocator can be used
+ * for each CPU.
+ *
+ * The lockless operation only works if there is enough memory
+ * available.  If new memory is added to the pool a lock has to be
+ * still taken.  So any user relying on locklessness has to ensure
+ * that sufficient memory is preallocated.
+ *
+ * The basic atomic operation of this allocator is cmpxchg on long.
+ * On architectures that don't have NMI-safe cmpxchg implementation,
+ * the allocator can NOT be used in NMI handler.  So code uses the
+ * allocator in NMI handler should depend on
+ * CONFIG_ARCH_HAVE_NMI_SAFE_CMPXCHG.

+ *	implementation may not sleep
+ * @dbg_show: optional routine to show contents in debugfs; default code
+ *	will be used when this is omitted, but custom code can show extra
+ *	state (such as pullup/pulldown configuration).
+ * @base: identifies the first GPIO number handled by this chip; or, if
+ *	negative during registration, requests dynamic ID allocation.
+ * @ngpio: the number of GPIOs handled by this controller; the last GPIO
+ *	handled is (base + ngpio - 1).
+ * @desc: array of ngpio descriptors. Private.
+ * @names: if set, must be an array of strings to use as alternative
+ *      names for the GPIOs in this chip. Any entry in the array
+ *      may be NULL if there is no alias for the GPIO, however the
+ *      array must be @ngpio entries long.  A name can include a single printk
+ *      format specifier for an unsigned int.  It is substituted by the actual
+ *      number of the gpio.
+ * @can_sleep: flag must be set iff get()/set() methods sleep, as they
+ *	must while accessing GPIO expander chips over I2C or SPI. This
+ *	implies that if the chip supports IRQs, these IRQs need to be threaded
+ *	as the chip access may sleep when e.g. reading out the IRQ status
+ *	registers.
+ * @exported: flags if the gpiochip is exported for use from sysfs. Private.
+ * @irq_not_threaded: flag must be set if @can_sleep is set but the
+ *	IRQs don't need to be threaded
+ *
+ * A gpio_chip can help platforms abstract various sources of GPIOs so
+ * they can all be accessed through a common programing interface.
+ * Example sources would be SOC controllers, FPGAs, multifunction
+ * chips, dedicated GPIO expanders, and so on.
+ *
+ * Each chip controls a number of signals, identified in method calls
+ * by "offset" values in the range 0..(@ngpio - 1).  When those signals
+ * are referenced through calls like gpio_get_value(gpio), the offset
+ * is calculated by subtracting @base from the gpio number.

+/**
+ * struct sx150x_platform_data - config data for SX150x driver
+ * @gpio_base: The index number of the first GPIO assigned to this
+ *             GPIO expander.  The expander will create a block of
+ *             consecutively numbered gpios beginning at the given base,
+ *             with the size of the block depending on the model of the
+ *             expander chip.
+ * @oscio_is_gpo: If set to true, the driver will configure OSCIO as a GPO
+ *                instead of as an oscillator, increasing the size of the
+ *                GP(I)O pool created by this expander by one.  The
+ *                output-only GPO pin will be added at the end of the block.
+ * @io_pullup_ena: A bit-mask which enables or disables the pull-up resistor
+ *                 for each IO line in the expander.  Setting the bit at
+ *                 position n will enable the pull-up for the IO at
+ *                 the corresponding offset.  For chips with fewer than
+ *                 16 IO pins, high-end bits are ignored.
+ * @io_pulldn_ena: A bit-mask which enables-or disables the pull-down
+ *                 resistor for each IO line in the expander. Setting the
+ *                 bit at position n will enable the pull-down for the IO at
+ *                 the corresponding offset.  For chips with fewer than
+ *                 16 IO pins, high-end bits are ignored.
+ * @io_open_drain_ena: A bit-mask which enables-or disables open-drain
+ *                     operation for each IO line in the expander. Setting the
+ *                     bit at position n enables open-drain operation for
+ *                     the IO at the corresponding offset.  Clearing the bit
+ *                     enables regular push-pull operation for that IO.
+ *                     For chips with fewer than 16 IO pins, high-end bits
+ *                     are ignored.
+ * @io_polarity: A bit-mask which enables polarity inversion for each IO line
+ *               in the expander.  Setting the bit at position n inverts
+ *               the polarity of that IO line, while clearing it results
+ *               in normal polarity. For chips with fewer than 16 IO pins,
+ *               high-end bits are ignored.
+ * @irq_summary: The 'summary IRQ' line to which the GPIO expander's INT line
+ *               is connected, via which it reports interrupt events
+ *               across all GPIO lines.  This must be a real,
+ *               pre-existing IRQ line.
+ *               Setting this value < 0 disables the irq_chip functionality
+ *               of the driver.
+ * @irq_base: The first 'virtual IRQ' line at which our block of GPIO-based
+ *            IRQ lines will appear.  Similarly to gpio_base, the expander
+ *            will create a block of irqs beginning at this number.
+ *            This value is ignored if irq_summary is < 0.
+ * @reset_during_probe: If set to true, the driver will trigger a full
+ *                      reset of the chip at the beginning of the probe
+ *                      in order to place it in a known state.

+ * If the function has a prototype somewhere, you can also add

+ * extern int initialize_foobar_device(int, int, int) __init;
+ *
+ * For initialized data:
+ * You should insert __initdata or __initconst between the variable name
+ * and equal sign followed by value, e.g.:
+ *
+ * static int init_variable __initdata = 0;
+ * static const char linux_logo[] __initconst = { 0x32, 0x36, ... };

+ *	Code that accesses and/or modifies parameters of a device

+ *	has been registered with input core must take this lock.
+ * @mutex: serializes calls to open(), close() and flush() methods
+ * @users: stores number of users (input handlers) that opened this
+ *	device. It is used by input_open_device() and input_close_device()

+ * and, unlike other attempts at IRQ probing, they do not get hung on
+ * stuck interrupts (such as unused PS2 mouse interfaces on ASUS boards).
+ *

+ * 2. sti();
+ * 3. irqs = probe_irq_on();      // "take over" all unassigned idle IRQs
+ * 4. enable the device and cause it to trigger an interrupt.
+ * 5. wait for the device to interrupt, using non-intrusive polling or a delay.
+ * 6. irq = probe_irq_off(irqs);  // get IRQ number, 0=none, negative=multiple
+ * 7. service the device to clear its pending interrupt.
+ * 8. loop again if paranoia is required.
+ *
+ * probe_irq_on() returns a mask of allocated irq's.
+ *
+ * probe_irq_off() takes the mask as a parameter,

+ * An io_cq (icq) is association between an io_context (ioc) and a
+ * request_queue (q).  This is used by elevators which need to track
+ * information per ioc - q pair.
+ *
+ * Elevator can request use of icq by setting elevator_type->icq_size and
+ * ->icq_align.  Both size and align must be larger than that of struct
+ * io_cq and elevator can use the tail area for private information.  The
+ * recommended way to do this is defining a struct which contains io_cq as
+ * the first member followed by private members and using its size and
+ * align.  For example,
+ *
+ *	struct snail_io_cq {
+ *		struct io_cq	icq;
+ *		int		poke_snail;
+ *		int		feed_snail;
+ *	};
+ *
+ *	struct elevator_type snail_elv_type {
+ *		.ops =		{ ... },
+ *		.icq_size =	sizeof(struct snail_io_cq),
+ *		.icq_align =	__alignof__(struct snail_io_cq),
+ *		...
+ *	};
+ *
+ * If icq_size is set, block core will manage icq's.  All requests will
+ * have its ->elv.icq field set before elevator_ops->elevator_set_req_fn()
+ * is called and be holding a reference to the associated io_context.
+ *
+ * Whenever a new icq is created, elevator_ops->elevator_init_icq_fn() is
+ * called and, on destruction, ->elevator_exit_icq_fn().  Both functions
+ * are called with both the associated io_context and queue locks held.
+ *
+ * Elevator is allowed to lookup icq using ioc_lookup_icq() while holding
+ * queue lock but the returned icq is valid only until the queue lock is
+ * released.  Elevators can not and should not try to create or destroy
+ * icq's.
+ *
+ * As icq's are linked from both ioc and q, the locking rules are a bit
+ * complex.
+ *
+ * - ioc lock nests inside q lock.
+ *
+ * - ioc->icq_list and icq->ioc_node are protected by ioc lock.
+ *   q->icq_list and icq->q_node by q lock.
+ *
+ * - ioc->icq_tree and ioc->icq_hint are protected by ioc lock, while icq
+ *   itself is protected by q lock.  However, both the indexes and icq
+ *   itself are also RCU managed and lookup can be performed holding only
+ *   the q lock.
+ *
+ * - icq's are not reference counted.  They are destroyed when either the
+ *   ioc or q goes away.  Each request with icq set holds an extra
+ *   reference to ioc to ensure it stays until the request is completed.
+ *
+ * - Linking and unlinking icq's are performed while holding both ioc and q
+ *   locks.  Due to the lock ordering, q exit is simple but ioc exit
+ *   requires reverse-order double lock dance.

+ * helpful for interrupt controllers to implement mapping between hardware
+ * irq numbers and the Linux irq number space.
+ *
+ * irq_domains also have a hook for translating device tree interrupt
+ * representation into a hardware irq number that can be mapped back to a
+ * Linux irq number without any extra platform support code.
+ *
+ * Interrupt controller "domain" data structure. This could be defined as a
+ * irq domain controller. That is, it handles the mapping between hardware
+ * and virtual interrupt numbers for a given interrupt domain. The domain
+ * structure is generally created by the PIC code for a given PIC instance
+ * (though a domain can cover more than one PIC if they have a flat number
+ * model). It's the domain callbacks that are responsible for setting the
+ * irq_chip on a given irq_desc after it's been mapped.
+ *
+ * The host code and data structures are agnostic to whether or not
+ * we use an open firmware device-tree. We do have references to struct
+ * device_node in two places: in irq_find_host() to find the host matching
+ * a given interrupt controller node, and of course as an argument to its
+ * counterpart domain->ops->match() callback. However, those are treated as
+ * generic pointers by the core and the fact that it's actually a device-node
+ * pointer is purely a convention between callers and implementation. This
+ * code could thus be used on other architectures by replacing those two
+ * by some sort of arch-specific void * "token" used to identify interrupt
+ * controllers.

+ * We want to do realistic conversions of time so we need to use the same
+ * values the update wall clock code uses as the jiffies size.  This value
+ * is: TICK_NSEC (which is defined in timex.h).  This
+ * is a constant and is in nanoseconds.  We will use scaled math
+ * with a set of scales defined here as SEC_JIFFIE_SC,  USEC_JIFFIE_SC and
+ * NSEC_JIFFIE_SC.  Note that these defines contain nothing but
+ * constants and so are computed at compile time.  SHIFT_HZ (computed in
+ * timex.h) adjusts the scaling for different HZ values.
+
+ * Scaled math???  What is that?
+ *
+ * Scaled math is a way to do integer math on values that would,
+ * otherwise, either overflow, underflow, or cause undesired div
+ * instructions to appear in the execution path.  In short, we "scale"
+ * up the operands so they take more bits (more precision, less
+ * underflow), do the desired operation and then "scale" the result back
+ * by the same amount.  If we do the scaling by shifting we avoid the
+ * costly mpy and the dastardly div instructions.
+
+ * Suppose, for example, we want to convert from seconds to jiffies
+ * where jiffies is defined in nanoseconds as NSEC_PER_JIFFIE.  The
+ * simple math is: jiff = (sec * NSEC_PER_SEC) / NSEC_PER_JIFFIE; We
+ * observe that (NSEC_PER_SEC / NSEC_PER_JIFFIE) is a constant which we
+ * might calculate at compile time, however, the result will only have
+ * about 3-4 bits of precision (less for smaller values of HZ).
+ *
+ * So, we scale as follows:
+ * jiff = (sec) * (NSEC_PER_SEC / NSEC_PER_JIFFIE);
+ * jiff = ((sec) * ((NSEC_PER_SEC * SCALE)/ NSEC_PER_JIFFIE)) / SCALE;
+ * Then we make SCALE a power of two so:
+ * jiff = ((sec) * ((NSEC_PER_SEC << SCALE)/ NSEC_PER_JIFFIE)) >> SCALE;
+ * Now we define:
+ * #define SEC_CONV = ((NSEC_PER_SEC << SCALE)/ NSEC_PER_JIFFIE))
+ * jiff = (sec * SEC_CONV) >> SCALE;
+ *
+ * Often the math we use will expand beyond 32-bits so we tell C how to
+ * do this and pass the 64-bit result of the mpy through the ">> SCALE"
+ * which should take the result back to 32-bits.  We want this expansion
+ * to capture as much precision as possible.  At the same time we don't
+ * want to overflow so we pick the SCALE to avoid this.  In this file,
+ * that means using a different scale for each range of HZ values (as
+ * defined in timex.h).
+ *
+ * For those who want to know, gcc will give a 64-bit result from a "*"
+ * operator if the result is a long long AND at least one of the
+ * operands is cast to long long (usually just prior to the "*" so as
+ * not to confuse it into thinking it really has a 64-bit operand,
+ * which, buy the way, it can do, but it takes more code and at least 2
+ * mpys).
+
+ * We also need to be aware that one second in nanoseconds is only a
+ * couple of bits away from overflowing a 32-bit word, so we MUST use
+ * 64-bits to get the full range time in nanoseconds.
+
+ */
+
+/*
+ * Here are the scales we will use.  One for seconds, nanoseconds and
+ * microseconds.
+ *
+ * Within the limits of cpp we do a rough cut at the SEC_JIFFIE_SC and
+ * check if the sign bit is set.  If not, we bump the shift count by 1.
+ * (Gets an extra bit of precision where we can use it.)
+ * We know it is set for HZ = 1024 and HZ = 100 not for 1000.

+ * Jump labels provide an interface to generate dynamic branches using
+ * self-modifying code. Assuming toolchain and architecture support, the result
+ * of a "if (static_key_false(&key))" statement is an unconditional branch (which
+ * defaults to false - and the true block is placed out of line).
+ *
+ * However at runtime we can change the branch target using
+ * static_key_slow_{inc,dec}(). These function as a 'reference' count on the key
+ * object, and for as long as there are references all branches referring to
+ * that particular key will point to the (out of line) true block.
+ *
+ * Since this relies on modifying code, the static_key_slow_{inc,dec}() functions
+ * must be considered absolute slow paths (machine wide synchronization etc.).
+ * OTOH, since the affected branches are unconditional, their runtime overhead
+ * will be absolutely minimal, esp. in the default (off) case where the total
+ * effect is a single NOP of appropriate size. The on case will patch in a jump
+ * to the out-of-line block.
+ *
+ * When the control is directly exposed to userspace, it is prudent to delay the
+ * decrement to avoid high frequency code modifications which can (and do)
+ * cause significant performance degradation. Struct static_key_deferred and
+ * static_key_slow_dec_deferred() provide for this.
+ *
+ * Lacking toolchain and or architecture support, jump labels fall back to a simple
+ * conditional branch.
+ *
+ * struct static_key my_key = STATIC_KEY_INIT_TRUE;
+ *
+ *   if (static_key_true(&my_key)) {
+ *   }
+ *
+ * will result in the true case being in-line and starts the key with a single
+ * reference. Mixing static_key_true() and static_key_false() on the same key is not
+ * allowed.
+ *
+ * Not initializing the key (static data is initialized to 0s anyway) is the
+ * same as using STATIC_KEY_INIT_FALSE.

+ * on the configuration. For example, interrupt detection block can use high
+ * pass filtered data which makes it react to the changes in the acceleration.
+ * Irq_flags can be used to enable interrupt detection on the both edges.

+ * If there are multiple producers and one consumer, llist_add can be

+ * in the consumer.
+ *

+ * add       |    -     |     -     |     -

+ * must reverse the order by yourself before traversing.
+ *
+ * The basic atomic operation of this list is cmpxchg on long.  On
+ * architectures that don't have NMI-safe cmpxchg implementation, the
+ * list can NOT be used in NMI handlers.  So code that uses the list in
+ * an NMI handler should depend on CONFIG_ARCH_HAVE_NMI_SAFE_CMPXCHG.

+This header file (and its .c file; kernel-doc of functions see there)
+  define a helper framework to easily keep track of index:label associations,
+  and changes to an "active set" of objects, as well as pending transactions,
+  to persistently record those changes.
+
+  We use an LRU policy if it is necessary to "cool down" a region currently in
+  the active set before we can "heat" a previously unused region.
+
+  Because of this later property, it is called "lru_cache".
+  As it actually Tracks Objects in an Active SeT, we could also call it
+  toast (incidentally that is what may happen to the data on the
+  backend storage uppon next resync, if we don't get it right).
+
+What for?
+
+We replicate IO (more or less synchronously) to local and remote disk.
+
+For crash recovery after replication node failure,
+  we need to resync all regions that have been target of in-flight WRITE IO
+  (in use, or "hot", regions), as we don't know whether or not those WRITEs
+  have made it to stable storage.
+
+  To avoid a "full resync", we need to persistently track these regions.
+
+  This is known as "write intent log", and can be implemented as on-disk
+  (coarse or fine grained) bitmap, or other meta data.
+
+  To avoid the overhead of frequent extra writes to this meta data area,
+  usually the condition is softened to regions that _may_ have been target of
+  in-flight WRITE IO, e.g. by only lazily clearing the on-disk write-intent
+  bitmap, trading frequency of meta data transactions against amount of
+  (possibly unnecessary) resync traffic.
+
+  If we set a hard limit on the area that may be "hot" at any given time, we
+  limit the amount of resync traffic needed for crash recovery.
+
+For recovery after replication link failure,
+  we need to resync all blocks that have been changed on the other replica
+  in the mean time, or, if both replica have been changed independently [*],
+  all blocks that have been changed on either replica in the mean time.
+  [*] usually as a result of a cluster split-brain and insufficient protection.
+      but there are valid use cases to do this on purpose.
+
+  Tracking those blocks can be implemented as "dirty bitmap".
+  Having it fine-grained reduces the amount of resync traffic.
+  It should also be persistent, to allow for reboots (or crashes)
+  while the replication link is down.
+
+There are various possible implementations for persistently storing
+write intent log information, three of which are mentioned here.
+
+"Chunk dirtying"
+  The on-disk "dirty bitmap" may be re-used as "write-intent" bitmap as well.
+  To reduce the frequency of bitmap updates for write-intent log purposes,
+  one could dirty "chunks" (of some size) at a time of the (fine grained)
+  on-disk bitmap, while keeping the in-memory "dirty" bitmap as clean as
+  possible, flushing it to disk again when a previously "hot" (and on-disk
+  dirtied as full chunk) area "cools down" again (no IO in flight anymore,
+  and none expected in the near future either).
+
+"Explicit (coarse) write intent bitmap"
+  An other implementation could chose a (probably coarse) explicit bitmap,
+  for write-intent log purposes, additionally to the fine grained dirty bitmap.
+
+"Activity log"
+  Yet an other implementation may keep track of the hot regions, by starting
+  with an empty set, and writing down a journal of region numbers that have
+  become "hot", or have "cooled down" again.
+
+  To be able to use a ring buffer for this journal of changes to the active
+  set, we not only record the actual changes to that set, but also record the
+  not changing members of the set in a round robin fashion. To do so, we use a
+  fixed (but configurable) number of slots which we can identify by index, and
+  associate region numbers (labels) with these indices.
+  For each transaction recording a change to the active set, we record the
+  change itself (index: -old_label, +new_label), and which index is associated
+  with which label (index: current_label) within a certain sliding window that
+  is moved further over the available indices with each such transaction.
+
+  Thus, for crash recovery, if the ringbuffer is sufficiently large, we can
+  accurately reconstruct the active set.
+
+  Sufficiently large depends only on maximum number of active objects, and the
+  size of the sliding window recording "index: current_label" associations within
+  each transaction.
+
+  This is what we call the "activity log".
+
+  Currently we need one activity log transaction per single label change, which
+  does not give much benefit over the "dirty chunks of bitmap" approach, other
+  than potentially less seeks.
+
+  We plan to change the transaction format to support multiple changes per
+  transaction, which then would reduce several (disjoint, "random") updates to
+  the bitmap into one transaction to the activity log ring buffer.
+*/
+
+/* this defines an element in a tracked set
+ * .colision is for hash table lookup.
+ * When we process a new IO request, we know its sector, thus can deduce the
+ * region number (label) easily.  To do the label -> object lookup without a
+ * full list walk, we use a simple hash table.
+ *
+ * .list is on one of three lists:
+ *  in_use: currently in use (refcnt > 0, lc_number != LC_FREE)
+ *     lru: unused but ready to be reused or recycled
+ *          (lc_refcnt == 0, lc_number != LC_FREE),
+ *    free: unused but ready to be recycled
+ *          (lc_refcnt == 0, lc_number == LC_FREE),
+ *
+ * an element is said to be "in the active set",
+ * if either on "in_use" or "lru", i.e. lc_number != LC_FREE.
+ *
+ * DRBD currently (May 2009) only uses 61 elements on the resync lru_cache
+ * (total memory usage 2 pages), and up to 3833 elements on the act_log
+ * lru_cache, totalling ~215 kB for 64bit architecture, ~53 pages.
+ *
+ * We usually do not actually free these objects again, but only "recycle"
+ * them, as the change "index: -old_label, +LC_FREE" would need a transaction
+ * as well.  Which also means that using a kmem_cache to allocate the objects
+ * from wastes some resources.
+ * But it avoids high order page allocations in kmalloc.

+ * Pages are allocated by the slab allocator in order to provide memory
+ * to kmalloc and kmem_cache_alloc. In this case, the management of the
+ * page, and the fields in 'struct page' are the responsibility of mm/slab.c
+ * unless a particular usage is carefully commented. (the responsibility of
+ * freeing the kmalloc memory is the caller's, of course).
+ *
+ * A page may be used by anyone else who does a __get_free_page().
+ * In this case, page_count still tracks the references, and should only
+ * be used through the normal accessor functions. The top bits of page->flags
+ * and page->virtual store page management information, but all other fields
+ * are unused and could be used privately, carefully. The management of this
+ * page is the responsibility of the one who allocated it, and those who have
+ * subsequently been given references to it.
+ *
+ * The other pages (we may call them "pagecache pages") are completely
+ * managed by the Linux memory manager: I/O, buffers, swapping etc.
+ * The following discussion applies only to them.
+ *
+ * A pagecache page contains an opaque `private' member, which belongs to the
+ * page's address_space. Usually, this is the address of a circular list of
+ * the page's disk buffers. PG_private must be set to tell the VM to call
+ * into the filesystem to release these pages.
+ *
+ * A page may belong to an inode's memory mapping. In this case, page->mapping
+ * is the pointer to the inode, and page->index is the file offset of the page,
+ * in units of PAGE_CACHE_SIZE.
+ *
+ * If pagecache pages are not associated with an inode, they are said to be
+ * anonymous pages. These may become associated with the swapcache, and in that
+ * case PG_swapcache is set, and page->private is an offset into the swapcache.
+ *
+ * In either case (swapcache or inode backed), the pagecache itself holds one
+ * reference to the page. Setting PG_private should also increment the
+ * refcount. The each user mapping also has a reference to the page.
+ *
+ * The pagecache pages are stored in a per-mapping radix tree, which is
+ * rooted at mapping->page_tree, and indexed by offset.
+ * Where 2.4 and early 2.6 kernels kept dirty/clean pages in per-address_space
+ * lists, we instead now tag pages as dirty/writeback in the radix tree.
+ *
+ * All pagecache pages may be subject to I/O:
+ * - inode pages may need to be read from disk,
+ * - inode pages which have been modified and are MAP_SHARED may need
+ *   to be written back to the inode on disk,
+ * - anonymous pages (including MAP_PRIVATE file mappings) which have been
+ *   modified may need to be swapped out to swap space and (later) to be read
+ *   back into memory.

+ * Locking
+ * =======
+ *
+ * @lock is a softirq-safe spinlock protecting @queue as well as
+ * @cur_slot, @mrq and @state. These must always be updated
+ * at the same time while holding @lock.
+ *
+ * @irq_lock is an irq-safe spinlock protecting the INTMASK register
+ * to allow the interrupt handler to modify it directly.  Held for only long
+ * enough to read-modify-write INTMASK and no other locks are grabbed when
+ * holding this one.
+ *
+ * The @mrq field of struct dw_mci_slot is also protected by @lock,
+ * and must always be written at the same time as the slot is added to
+ * @queue.
+ *
+ * @pending_events and @completed_events are accessed using atomic bit
+ * operations, so they don't need any locking.
+ *
+ * None of the fields touched by the interrupt handler need any
+ * locking. However, ordering is important: Before EVENT_DATA_ERROR or
+ * EVENT_DATA_COMPLETE is set in @pending_events, all data-related
+ * interrupts must be disabled and @data_status updated with a
+ * snapshot of SR. Similarly, before EVENT_CMD_COMPLETE is set, the
+ * CMDRDY interrupt must be disabled and @cmd_status updated with a
+ * snapshot of SR, and before EVENT_XFER_COMPLETE can be set, the
+ * bytes_xfered field of @data must be written. This is ensured by
+ * using barriers.

+ *    we zero'd fullzones.
+ * 2) The array z_to_n[] maps each zone in the zonelist to its node
+ *    id, so that we can efficiently evaluate whether that node is
+ *    set in the current tasks mems_allowed.
+ *
+ * Both fullzones and z_to_n[] are one-to-one with the zonelist,
+ * indexed by a zones offset in the zonelist zones[] array.
+ *
+ * The get_page_from_freelist() routine does two scans.  During the
+ * first scan, we skip zones whose corresponding bit in 'fullzones'
+ * is set or whose corresponding node in current->mems_allowed (which
+ * comes from cpusets) is not set.  During the second scan, we bypass
+ * this zonelist_cache, to ensure we look methodically at each zone.
+ *
+ * Once per second, we zero out (zap) fullzones, forcing us to
+ * reconsider nodes that might have regained more free memory.
+ * The field last_full_zap is the time we last zapped fullzones.
+ *
+ * This mechanism reduces the amount of time we waste repeatedly
+ * reexaming zones for free memory when they just came up low on
+ * memory momentarilly ago.
+ *
+ * The zonelist_cache struct members logically belong in struct
+ * zonelist.  However, the mempolicy zonelists constructed for
+ * MPOL_BIND are intentionally variable length (and usually much
+ * shorter).  A general purpose mechanism for handling structs with
+ * multiple variable length members is more mechanism than we want
+ * here.  We resort to some special case hackery instead.
+ *
+ * The MPOL_BIND zonelists don't need this zonelist_cache (in good
+ * part because they are shorter), so we put the fixed length stuff
+ * at the front of the zonelist struct, ending in a variable length
+ * zones[], as is needed by MPOL_BIND.
+ *
+ * Then we put the optional zonelist cache on the end of the zonelist
+ * struct.  This optional stuff is found by a 'zlcache_ptr' pointer in
+ * the fixed length portion at the front of the struct.  This pointer
+ * both enables us to find the zonelist cache, and in the case of
+ * MPOL_BIND zonelists, (which will just set the zlcache_ptr to NULL)
+ * to know that the zonelist cache is not there.
+ *
+ * The end result is that struct zonelists come in two flavors:
+ *  1) The full, fixed length version, shown below, and
+ *  2) The custom zonelists for MPOL_BIND.
+ * The custom MPOL_BIND zonelists have a NULL zlcache_ptr and no zlcache.
+ *
+ * Even though there may be multiple CPU cores on a node modifying
+ * fullzones or last_full_zap in the same zonelist_cache at the same
+ * time, we don't lock it.  This is just hint data - if it is wrong now
+ * and then, the allocator will still function, perhaps a bit slower.

+ *	match against new devices. Any field except for driver_info may be
+ *	used, although some only make sense in conjunction with other fields.
+ *	This is usually set by a USB_DEVICE_*() macro, which sets all
+ *	other fields in this structure except for driver_info.
+ * @idVendor: USB vendor ID for a device; numbers are assigned
+ *	by the USB forum to its members.
+ * @idProduct: Vendor-assigned product ID.
+ * @bcdDevice_lo: Low end of range of vendor-assigned product version numbers.
+ *	This is also used to identify individual product versions, for
+ *	a range consisting of a single device.
+ * @bcdDevice_hi: High end of version number range.  The range of product
+ *	versions is inclusive.
+ * @bDeviceClass: Class of device; numbers are assigned
+ *	by the USB forum.  Products may choose to implement classes,
+ *	or be vendor-specific.  Device classes specify behavior of all
+ *	the interfaces on a device.
+ * @bDeviceSubClass: Subclass of device; associated with bDeviceClass.
+ * @bDeviceProtocol: Protocol of device; associated with bDeviceClass.
+ * @bInterfaceClass: Class of interface; numbers are assigned
+ *	by the USB forum.  Products may choose to implement classes,
+ *	or be vendor-specific.  Interface classes specify behavior only
+ *	of a given interface; other interfaces may support other classes.
+ * @bInterfaceSubClass: Subclass of interface; associated with bInterfaceClass.
+ * @bInterfaceProtocol: Protocol of interface; associated with bInterfaceClass.
+ * @bInterfaceNumber: Number of interface; composite devices may use
+ *	fixed interface numbers to differentiate between vendor-specific
+ *	interfaces.
+ * @driver_info: Holds information used by the driver.  Usually it holds
+ *	a pointer to a descriptor understood by the driver, or perhaps
+ *	device flags.
+ *
+ * In most cases, drivers will create a table of device IDs by using
+ * USB_DEVICE(), or similar macros designed for that purpose.
+ * They will then export it to userspace using MODULE_DEVICE_TABLE(),
+ * and provide it to the USB core through their usb_driver structure.
+ *
+ * See the usb_match_id() function for information about how matches are
+ * performed.  Briefly, you will normally use one of several macros to help
+ * construct these entries.  Each entry you provide will either identify
+ * one or more specific products, or will identify a class of products
+ * which have agreed to behave the same.  You should put the more specific
+ * matches towards the beginning of your table, so that driver_info can
+ * record quirks of specific products.

+ * @name_len: volume name length
+ * @name: volume name
+ * @cdev: UBI volume character device major and minor numbers
+ *
+ * The @corrupted flag is only relevant to static volumes and is always zero
+ * for dynamic ones. This is because UBI does not care about dynamic volume
+ * data protection and only cares about protecting static volume data.
+ *
+ * The @upd_marker flag is set if the volume update operation was interrupted.
+ * Before touching the volume data during the update operation, UBI first sets
+ * the update marker flag for this volume. If the volume update operation was
+ * further interrupted, the update marker indicates this. If the update marker
+ * is set, the contents of the volume is certainly damaged and a new volume
+ * update operation has to be started.
+ *
+ * To put it differently, @corrupted and @upd_marker fields have different
+ * semantics:
+ *     o the @corrupted flag means that this static volume is corrupted for some
+ *       reasons, but not because an interrupted volume update
+ *     o the @upd_marker field means that the volume is damaged because of an
+ *       interrupted update operation.
+ *
+ * I.e., the @corrupted flag is never set if the @upd_marker flag is set.
+ *
+ * The @used_bytes and @used_ebs fields are only really needed for static
+ * volumes and contain the number of bytes stored in this static volume and how
+ * many eraseblock this data occupies. In case of dynamic volumes, the
+ * @used_bytes field is equivalent to @size*@usable_leb_size, and the @used_ebs
+ * field is equivalent to @size.
+ *
+ * In general, logical eraseblock size is a property of the UBI device, not
+ * of the UBI volume. Indeed, the logical eraseblock size depends on the
+ * physical eraseblock size and on how much bytes UBI headers consume. But
+ * because of the volume alignment (@alignment), the usable size of logical
+ * eraseblocks if a volume may be less. The following equation is true:
+ *	@usable_leb_size = LEB size - (LEB size mod @alignment),
+ * where LEB size is the logical eraseblock size defined by the UBI device.
+ *
+ * The alignment is multiple to the minimal flash input/output unit size or %1
+ * if all the available space is used.
+ *
+ * To put this differently, alignment may be considered is a way to change
+ * volume logical eraseblock sizes.

+/****************************************************************************
+ * ip_conntrack_h323_asn1.h - BER and PER decoding library for H.323
+ * 			      conntrack/NAT module.
+ *
+ * Copyright (c) 2006 by Jing Min Zhao <zhaojingmin@users.sourceforge.net>
+ *
+ * This source code is licensed under General Public License version 2.
+ *
+ *
+ * This library is based on H.225 version 4, H.235 version 2 and H.245
+ * version 7. It is extremely optimized to decode only the absolutely
+ * necessary objects in a signal for Linux kernel NAT module use, so don't
+ * expect it to be a full ASN.1 library.
+ *
+ * Features:
+ *
+ * 1. Small. The total size of code plus data is less than 20 KB (IA32).
+ * 2. Fast. Decoding Netmeeting's Setup signal 1 million times on a PIII 866
+ *    takes only 3.9 seconds.
+ * 3. No memory allocation. It uses a static object. No need to initialize or
+ *    cleanup.
+ * 4. Thread safe.
+ * 5. Support embedded architectures that has no misaligned memory access
+ *    support.
+ *
+ * Limitations:
+ *
+ * 1. At most 30 faststart entries. Actually this is limited by ethernet's MTU.
+ *    If a Setup signal contains more than 30 faststart, the packet size will
+ *    very likely exceed the MTU size, then the TPKT will be fragmented. I
+ *    don't know how to handle this in a Netfilter module. Anybody can help?
+ *    Although I think 30 is enough for most of the cases.
+ * 2. IPv4 addresses only.

+ * PG_error is set to indicate that an I/O error occurred on this page.

+ * PG_arch_1 is an architecture specific page state bit.  The generic code
+ * guarantees that this bit is cleared for a page when it first is entered into
+ * the page cache.
+ *
+ * PG_highmem pages are not permanently mapped into the kernel virtual address
+ * space, they need to be kmapped separately for doing IO on the pages.  The
+ * struct page (these bits with information) are always mapped into kernel
+ * address space...

+ * This function must be called inside the same rcu_read_lock() section as has

+ * this allows allocators to use a synchronize_rcu() to stabilize _count.
+ *
+ * Unless an RCU grace period has passed, the count of all pages coming out

+ * than expected, and put_page must be able to do the right thing when the
+ * page has been finished with, no matter what it is subsequently allocated
+ * for (because put_page is what is used here to drop an invalid speculative
+ * reference).
+ *
+ * This is the interesting part of the lockless pagecache (and lockless
+ * get_user_pages) locking protocol, where the lookup-side (eg. find_get_page)
+ * has the following pattern:
+ * 1. find page in radix tree
+ * 2. conditionally increment refcount
+ * 3. check the page is still in pagecache (if no, goto 1)
+ *
+ * Remove-side that cares about stability of _count (eg. reclaim) has the
+ * following (with tree_lock held for write):
+ * A. atomically check refcount is correct and set it to 0 (atomic_cmpxchg)
+ * B. remove page from pagecache
+ * C. free the page
+ *
+ * There are 2 critical interleavings that matter:
+ * - 2 runs before A: in this case, A sees elevated refcount and bails out
+ * - A runs before 2: in this case, 2 sees zero refcount and retries;
+ *   subsequently, B will complete and 1 will find no page, causing the
+ *   lookup to return NULL.
+ *
+ * It is possible that between 1 and 2, the page is removed then the exact same

+ * Percpu refcounts:
+ * (C) 2012 Google, Inc.
+ * Author: Kent Overstreet <koverstreet@google.com>
+ *
+ * This implements a refcount with similar semantics to atomic_t - atomic_inc(),
+ * atomic_dec_and_test() - but percpu.
+ *
+ * There's one important difference between percpu refs and normal atomic_t
+ * refcounts; you have to keep track of your initial refcount, and then when you
+ * start shutting down you call percpu_ref_kill() _before_ dropping the initial
+ * refcount.
+ *
+ * The refcount will have a range of 0 to ((1U << 31) - 1), i.e. one bit less
+ * than an atomic_t - this is because of the way shutdown works, see
+ * percpu_ref_kill()/PERCPU_COUNT_BIAS.
+ *
+ * Before you call percpu_ref_kill(), percpu_ref_put() does not check for the
+ * refcount hitting 0 - it can't, if it was in percpu mode. percpu_ref_kill()
+ * puts the ref back in single atomic_t mode, collecting the per cpu refs and
+ * issuing the appropriate barriers, and then marks the ref as shutting down so
+ * that percpu_ref_put() will check for the ref hitting 0.  After it returns,
+ * it's safe to drop the initial ref.
+ *
+ * USAGE:
+ *
+ * See fs/aio.c for some example usage; it's used there for struct kioctx, which
+ * is created when userspaces calls io_setup(), and destroyed when userspace
+ * calls io_destroy() or the process exits.
+ *
+ * In the aio code, kill_ioctx() is called when we wish to destroy a kioctx; it
+ * calls percpu_ref_kill(), then hlist_del_rcu() and synchronize_rcu() to remove
+ * the kioctx from the proccess's list of kioctxs - after that, there can't be
+ * any new users of the kioctx (from lookup_ioctx()) and it's then safe to drop
+ * the initial ref with percpu_ref_put().
+ *
+ * Code that does a two stage shutdown like this often needs some kind of
+ * explicit synchronization to ensure the initial refcount can only be dropped
+ * once - percpu_ref_kill() does this for you, it returns true once and false if
+ * someone else already called it. The aio code uses it this way, but it's not
+ * necessary if the code has some other mechanism to synchronize teardown.
+ * around.

+ * whenever called with phydev->autoneg set to AUTONEG_ENABLE.
+ * - If autonegotiation finishes, but there's no link, it sets
+ *   the state to NOLINK.
+ * - If aneg finishes with link, it sets the state to RUNNING,

+ * - If autonegotiation did not finish after an arbitrary amount
+ *   of time, autonegotiation should be tried again if the PHY
+ *   supports "magic" autonegotiation (back to AN)
+ * - If it didn't finish, and no magic_aneg, move to FORCING.
+ *
+ * NOLINK: PHY is up, but not currently plugged in.
+ * - If the timer notes that the link comes back, we move to RUNNING
+ * - config_aneg moves to AN
+ * - phy_stop moves to HALTED
+ *
+ * FORCING: PHY is being configured with forced settings
+ * - if link is up, move to RUNNING
+ * - If link is down, we drop to the next highest setting, and
+ *   retry (FORCING) after a timeout
+ * - phy_stop moves to HALTED
+ *
+ * RUNNING: PHY is currently up, running, and possibly sending
+ * and/or receiving packets
+ * - timer will set CHANGELINK if we're polling (this ensures the
+ *   link state is polled every other cycle of this state machine,
+ *   which makes it every other second)
+ * - irq will set CHANGELINK
+ * - config_aneg will set AN
+ * - phy_stop moves to HALTED

+ * What is struct pid?
+ *
+ * A struct pid is the kernel's internal notion of a process identifier.
+ * It refers to individual tasks, process groups, and sessions.  While
+ * there are processes attached to it the struct pid lives in a hash
+ * table, so it and then the processes that it refers to can be found
+ * quickly from the numeric pid value.  The attached processes may be
+ * quickly accessed by following pointers from struct pid.
+ *
+ * Storing pid_t values in the kernel and referring to them later has a
+ * problem.  The process originally with that pid may have exited and the
+ * pid allocator wrapped, and another process could have come along
+ * and been assigned that pid.
+ *
+ * Referring to user space processes by holding a reference to struct
+ * task_struct has a problem.  When the user space process exits
+ * the now useless task_struct is still kept.  A task_struct plus a
+ * stack consumes around 10K of low kernel memory.  More precisely
+ * this is THREAD_SIZE + sizeof(struct task_struct).  By comparison
+ * a struct pid is about 64 bytes.
+ *
+ * Holding a reference to struct pid solves both of these problems.
+ * It is small so holding a reference does not consume a lot of
+ * resources, and since a new struct pid is allocated when the numeric pid
+ * value is reused (when pids wrap around) we don't mistakenly refer to new
+ * processes.

+/**
+ * enum pin_config_param - possible pin configuration parameters
+ * @PIN_CONFIG_BIAS_DISABLE: disable any pin bias on the pin, a
+ *	transition from say pull-up to pull-down implies that you disable
+ *	pull-up in the process, this setting disables all biasing.
+ * @PIN_CONFIG_BIAS_HIGH_IMPEDANCE: the pin will be set to a high impedance
+ *	mode, also know as "third-state" (tristate) or "high-Z" or "floating".
+ *	On output pins this effectively disconnects the pin, which is useful
+ *	if for example some other pin is going to drive the signal connected
+ *	to it for a while. Pins used for input are usually always high
+ *	impedance.
+ * @PIN_CONFIG_BIAS_BUS_HOLD: the pin will be set to weakly latch so that it
+ *	weakly drives the last value on a tristate bus, also known as a "bus
+ *	holder", "bus keeper" or "repeater". This allows another device on the
+ *	bus to change the value by driving the bus high or low and switching to
+ *	tristate. The argument is ignored.
+ * @PIN_CONFIG_BIAS_PULL_UP: the pin will be pulled up (usually with high
+ *	impedance to VDD). If the argument is != 0 pull-up is enabled,
+ *	if it is 0, pull-up is total, i.e. the pin is connected to VDD.
+ * @PIN_CONFIG_BIAS_PULL_DOWN: the pin will be pulled down (usually with high
+ *	impedance to GROUND). If the argument is != 0 pull-down is enabled,
+ *	if it is 0, pull-down is total, i.e. the pin is connected to GROUND.
+ * @PIN_CONFIG_BIAS_PULL_PIN_DEFAULT: the pin will be pulled up or down based
+ *	on embedded knowledge of the controller hardware, like current mux
+ *	function. The pull direction and possibly strength too will normally
+ *	be decided completely inside the hardware block and not be readable
+ *	from the kernel side.
+ *	If the argument is != 0 pull up/down is enabled, if it is 0, the
+ *	configuration is ignored. The proper way to disable it is to use
+ *	@PIN_CONFIG_BIAS_DISABLE.
+ * @PIN_CONFIG_DRIVE_PUSH_PULL: the pin will be driven actively high and
+ *	low, this is the most typical case and is typically achieved with two
+ *	active transistors on the output. Setting this config will enable
+ *	push-pull mode, the argument is ignored.
+ * @PIN_CONFIG_DRIVE_OPEN_DRAIN: the pin will be driven with open drain (open
+ *	collector) which means it is usually wired with other output ports
+ *	which are then pulled up with an external resistor. Setting this
+ *	config will enable open drain mode, the argument is ignored.
+ * @PIN_CONFIG_DRIVE_OPEN_SOURCE: the pin will be driven with open source
+ *	(open emitter). Setting this config will enable open source mode, the
+ *	argument is ignored.
+ * @PIN_CONFIG_DRIVE_STRENGTH: the pin will sink or source at most the current
+ *	passed as argument. The argument is in mA.
+ * @PIN_CONFIG_INPUT_ENABLE: enable the pin's input.  Note that this does not
+ *	affect the pin's ability to drive output.  1 enables input, 0 disables
+ *	input.
+ * @PIN_CONFIG_INPUT_SCHMITT_ENABLE: control schmitt-trigger mode on the pin.
+ *      If the argument != 0, schmitt-trigger mode is enabled. If it's 0,
+ *      schmitt-trigger mode is disabled.
+ * @PIN_CONFIG_INPUT_SCHMITT: this will configure an input pin to run in
+ *	schmitt-trigger mode. If the schmitt-trigger has adjustable hysteresis,
+ *	the threshold value is given on a custom format as argument when
+ *	setting pins to this mode.
+ * @PIN_CONFIG_INPUT_DEBOUNCE: this will configure the pin to debounce mode,
+ *	which means it will wait for signals to settle when reading inputs. The
+ *	argument gives the debounce time in usecs. Setting the
+ *	argument to zero turns debouncing off.
+ * @PIN_CONFIG_POWER_SOURCE: if the pin can select between different power
+ *	supplies, the argument to this parameter (on a custom format) tells
+ *	the driver which alternative power source to use.
+ * @PIN_CONFIG_SLEW_RATE: if the pin can select slew rate, the argument to
+ *	this parameter (on a custom format) tells the driver which alternative
+ *	slew rate to use.
+ * @PIN_CONFIG_LOW_POWER_MODE: this will configure the pin for low power
+ *	operation, if several modes of operation are supported these can be
+ *	passed in the argument on a custom form, else just use argument 1
+ *	to indicate low power mode, argument 0 turns low power mode off.
+ * @PIN_CONFIG_OUTPUT: this will configure the pin as an output. Use argument
+ *	1 to indicate high level, argument 0 to indicate low level. (Please
+ *	see Documentation/pinctrl.txt, section "GPIO mode pitfalls" for a
+ *	discussion around this parameter.)

+static void brcmfmac_power_on(void)
+{
+}
+
+static void brcmfmac_power_off(void)
+{
+}
+
+static void brcmfmac_reset(void)
+{
+}
+
+static struct brcmfmac_sdio_platform_data brcmfmac_sdio_pdata = {
+	.power_on		= brcmfmac_power_on,
+	.power_off		= brcmfmac_power_off,
+	.reset			= brcmfmac_reset
+};
+
+static struct platform_device brcmfmac_device = {
+	.name			= BRCMFMAC_SDIO_PDATA_NAME,
+	.id			= PLATFORM_DEVID_NONE,
+	.dev.platform_data	= &brcmfmac_sdio_pdata
+};
+
+void __init brcmfmac_init_pdata(void)
+{
+	brcmfmac_sdio_pdata.oob_irq_supported = true;
+	brcmfmac_sdio_pdata.oob_irq_nr = gpio_to_irq(GPIO_BRCMF_SDIO_OOB);
+	brcmfmac_sdio_pdata.oob_irq_flags = IORESOURCE_IRQ |
+					    IORESOURCE_IRQ_HIGHLEVEL;
+	platform_device_register(&brcmfmac_device);
+}
+ *
+ *
+ * Note: the brcmfmac can be loaded as module or be statically built-in into
+ * the kernel. If built-in then do note that it uses module_init (and
+ * module_exit) routines which equal device_initcall. So if you intend to
+ * create a module with the platform specific data for the brcmfmac and have
+ * it built-in to the kernel then use a higher initcall then device_initcall
+ * (see init.h). If this is not done then brcmfmac will load without problems
+ * but will not pickup the platform data.
+ *
+ * When the driver does not "detect" platform driver data then it will continue
+ * without reporting anything and just assume there is no data needed. Which is
+ * probably true for most platforms.
+ *
+ * Explanation of the platform_data fields:
+ *
+ * drive_strength: is the preferred drive_strength to be used for the SDIO
+ * pins. If 0 then a default value will be used. This is the target drive
+ * strength, the exact drive strength which will be used depends on the
+ * capabilities of the device.
+ *
+ * oob_irq_supported: does the board have support for OOB interrupts. SDIO
+ * in-band interrupts are relatively slow and for having less overhead on
+ * interrupt processing an out of band interrupt can be used. If the HW
+ * supports this then enable this by setting this field to true and configure
+ * the oob related fields.
+ *
+ * oob_irq_nr, oob_irq_flags: the OOB interrupt information. The values are
+ * used for registering the irq using request_irq function.
+ *
+ * broken_sg_support: flag for broken sg list support of SDIO host controller.
+ * Set this to true if the SDIO host controller has higher align requirement
+ * than 32 bytes for each scatterlist item.
+ *
+ * sd_head_align: alignment requirement for start of data buffer
+ *
+ * sd_sgentry_align: length alignment requirement for each sg entry
+ *
+ * power_on: This function is called by the brcmfmac when the module gets
+ * loaded. This can be particularly useful for low power devices. The platform
+ * spcific routine may for example decide to power up the complete device.
+ * If there is no use-case for this function then provide NULL.
+ *
+ * power_off: This function is called by the brcmfmac when the module gets
+ * unloaded. At this point the device can be powered down or otherwise be reset.
+ * So if an actual power_off is not supported but reset is then reset the device
+ * when this function gets called. This can be particularly useful for low power
+ * devices. If there is no use-case for this function (either power-down or
+ * reset) then provide NULL.
+ *
+ * reset: This function can get called if the device communication broke down.
+ * This functionality is particularly useful in case of SDIO type devices. It is
+ * possible to reset a dongle via sdio data interface, but it requires that
+ * this is fully functional. This function is chip/module specific and this
+ * function should return only after the complete reset has completed.

+ * This EDMA3 programming framework exposes two basic kinds of resource:
+ *
+ *  Channel	Triggers transfers, usually from a hardware event but
+ *		also manually or by "chaining" from DMA completions.
+ *		Each channel is coupled to a Parameter RAM (PaRAM) slot.
+ *
+ *  Slot	Each PaRAM slot holds a DMA transfer descriptor (PaRAM
+ *		"set"), source and destination addresses, a link to a
+ *		next PaRAM slot (if any), options for the transfer, and
+ *		instructions for updating those addresses.  There are
+ *		more than twice as many slots as event channels.
+ *
+ * Each PaRAM set describes a sequence of transfers, either for one large
+ * buffer or for several discontiguous smaller buffers.  An EDMA transfer
+ * is driven only from a channel, which performs the transfers specified
+ * in its PaRAM slot until there are no more transfers.  When that last
+ * transfer completes, the "link" field may be used to reload the channel's
+ * PaRAM slot with a new transfer descriptor.
+ *
+ * The EDMA Channel Controller (CC) maps requests from channels into physical
+ * Transfer Controller (TC) requests when the channel triggers (by hardware
+ * or software events, or by chaining).  The two physical DMA channels provided
+ * by the TCs are thus shared by many logical channels.
+ *
+ * DaVinci hardware also has a "QDMA" mechanism which is not currently
+ * supported through this interface.  (DSP firmware uses it though.)

+ * Licensed under the FSF's GNU Public License v2 or later.
+ *
+ * Based on simple lists (include/linux/list.h).
+ *
+ * This is a priority-sorted list of nodes; each node has a
+ * priority from INT_MIN (highest) to INT_MAX (lowest).
+ *
+ * Addition is O(K), removal is O(1), change of priority of a node is
+ * O(K) and K is the number of RT priority levels used in the system.
+ * (1 <= K <= 99)
+ *
+ * This list is really a list of lists:
+ *
+ *  - The tier 1 list is the prio_list, different priority nodes.
+ *
+ *  - The tier 2 list is the node_list, serialized nodes.
+ *
+ * Simple ASCII art explanation:
+ *
+ * pl:prio_list (only for plist_node)
+ * nl:node_list
+ *   HEAD|             NODE(S)
+ *       |
+ *       ||------------------------------------|
+ *       ||->|pl|<->|pl|<--------------->|pl|<-|
+ *       |   |10|   |21|   |21|   |21|   |40|   (prio)
+ *       |   |  |   |  |   |  |   |  |   |  |
+ *       |   |  |   |  |   |  |   |  |   |  |
+ * |->|nl|<->|nl|<->|nl|<->|nl|<->|nl|<->|nl|<-|
+ * |-------------------------------------------|
+ *
+ * The nodes on the prio_list list are sorted by priority to simplify
+ * the insertion of new nodes. There are no nodes with duplicate
+ * priorites on the list.
+ *
+ * The nodes on the node_list are ordered by priority and can contain
+ * entries which have the same priority. Those entries are ordered
+ * FIFO
+ *
+ * Addition means: look for the prio_list node in the prio_list
+ * for the priority of the node and insert it before the node_list
+ * entry of the next prio_list node. If it is the first node of
+ * that priority, add it to the prio_list in the right position and
+ * insert it into the serialized node_list list
+ *
+ * Removal means remove it from the node_list and remove it from
+ * the prio_list if the node_list list_head is non empty. In case
+ * of removal from the prio_list it must be checked whether other
+ * entries of the same priority are on the list or not. If there
+ * is another entry of the same priority then this entry has to
+ * replace the removed entry on the prio_list. If the entry which
+ * is removed is the only entry of this priority then a simple
+ * remove from both list is sufficient.
+ *
+ * INT_MIN is the highest priority, 0 is the medium highest, INT_MAX
+ * is lowest priority.
+ *
+ * No locking is done, up to the caller.

+/**
+ * struct dev_pm_ops - device PM callbacks
+ *
+ * Several device power state transitions are externally visible, affecting
+ * the state of pending I/O queues and (for drivers that touch hardware)
+ * interrupts, wakeups, DMA, and other hardware state.  There may also be
+ * internal transitions to various low-power modes which are transparent
+ * to the rest of the driver stack (such as a driver that's ON gating off
+ * clocks which are not in active use).
+ *
+ * The externally visible transitions are handled with the help of callbacks
+ * included in this structure in such a way that two levels of callbacks are
+ * involved.  First, the PM core executes callbacks provided by PM domains,
+ * device types, classes and bus types.  They are the subsystem-level callbacks
+ * supposed to execute callbacks provided by device drivers, although they may
+ * choose not to do that.  If the driver callbacks are executed, they have to
+ * collaborate with the subsystem-level callbacks to achieve the goals
+ * appropriate for the given system transition, given transition phase and the
+ * subsystem the device belongs to.
+ *
+ * @prepare: The principal role of this callback is to prevent new children of
+ *	the device from being registered after it has returned (the driver's
+ *	subsystem and generally the rest of the kernel is supposed to prevent
+ *	new calls to the probe method from being made too once @prepare() has
+ *	succeeded).  If @prepare() detects a situation it cannot handle (e.g.
+ *	registration of a child already in progress), it may return -EAGAIN, so
+ *	that the PM core can execute it once again (e.g. after a new child has
+ *	been registered) to recover from the race condition.
+ *	This method is executed for all kinds of suspend transitions and is
+ *	followed by one of the suspend callbacks: @suspend(), @freeze(), or
+ *	@poweroff().  If the transition is a suspend to memory or standby (that
+ *	is, not related to hibernation), the return value of @prepare() may be
+ *	used to indicate to the PM core to leave the device in runtime suspend
+ *	if applicable.  Namely, if @prepare() returns a positive number, the PM
+ *	core will understand that as a declaration that the device appears to be
+ *	runtime-suspended and it may be left in that state during the entire
+ *	transition and during the subsequent resume if all of its descendants
+ *	are left in runtime suspend too.  If that happens, @complete() will be
+ *	executed directly after @prepare() and it must ensure the proper
+ *	functioning of the device after the system resume.
+ *	The PM core executes subsystem-level @prepare() for all devices before
+ *	starting to invoke suspend callbacks for any of them, so generally
+ *	devices may be assumed to be functional or to respond to runtime resume
+ *	requests while @prepare() is being executed.  However, device drivers
+ *	may NOT assume anything about the availability of user space at that
+ *	time and it is NOT valid to request firmware from within @prepare()
+ *	(it's too late to do that).  It also is NOT valid to allocate
+ *	substantial amounts of memory from @prepare() in the GFP_KERNEL mode.
+ *	[To work around these limitations, drivers may register suspend and
+ *	hibernation notifiers to be executed before the freezing of tasks.]
+ *
+ * @complete: Undo the changes made by @prepare().  This method is executed for
+ *	all kinds of resume transitions, following one of the resume callbacks:
+ *	@resume(), @thaw(), @restore().  Also called if the state transition
+ *	fails before the driver's suspend callback: @suspend(), @freeze() or
+ *	@poweroff(), can be executed (e.g. if the suspend callback fails for one
+ *	of the other devices that the PM core has unsuccessfully attempted to
+ *	suspend earlier).
+ *	The PM core executes subsystem-level @complete() after it has executed
+ *	the appropriate resume callbacks for all devices.  If the corresponding
+ *	@prepare() at the beginning of the suspend transition returned a
+ *	positive number and the device was left in runtime suspend (without
+ *	executing any suspend and resume callbacks for it), @complete() will be
+ *	the only callback executed for the device during resume.  In that case,
+ *	@complete() must be prepared to do whatever is necessary to ensure the
+ *	proper functioning of the device after the system resume.  To this end,
+ *	@complete() can check the power.direct_complete flag of the device to
+ *	learn whether (unset) or not (set) the previous suspend and resume
+ *	callbacks have been executed for it.
+ *
+ * @suspend: Executed before putting the system into a sleep state in which the
+ *	contents of main memory are preserved.  The exact action to perform
+ *	depends on the device's subsystem (PM domain, device type, class or bus
+ *	type), but generally the device must be quiescent after subsystem-level
+ *	@suspend() has returned, so that it doesn't do any I/O or DMA.
+ *	Subsystem-level @suspend() is executed for all devices after invoking
+ *	subsystem-level @prepare() for all of them.
+ *
+ * @suspend_late: Continue operations started by @suspend().  For a number of
+ *	devices @suspend_late() may point to the same callback routine as the
+ *	runtime suspend callback.
+ *
+ * @resume: Executed after waking the system up from a sleep state in which the
+ *	contents of main memory were preserved.  The exact action to perform
+ *	depends on the device's subsystem, but generally the driver is expected
+ *	to start working again, responding to hardware events and software
+ *	requests (the device itself may be left in a low-power state, waiting
+ *	for a runtime resume to occur).  The state of the device at the time its
+ *	driver's @resume() callback is run depends on the platform and subsystem
+ *	the device belongs to.  On most platforms, there are no restrictions on
+ *	availability of resources like clocks during @resume().
+ *	Subsystem-level @resume() is executed for all devices after invoking
+ *	subsystem-level @resume_noirq() for all of them.
+ *
+ * @resume_early: Prepare to execute @resume().  For a number of devices
+ *	@resume_early() may point to the same callback routine as the runtime
+ *	resume callback.
+ *
+ * @freeze: Hibernation-specific, executed before creating a hibernation image.
+ *	Analogous to @suspend(), but it should not enable the device to signal
+ *	wakeup events or change its power state.  The majority of subsystems
+ *	(with the notable exception of the PCI bus type) expect the driver-level
+ *	@freeze() to save the device settings in memory to be used by @restore()
+ *	during the subsequent resume from hibernation.
+ *	Subsystem-level @freeze() is executed for all devices after invoking
+ *	subsystem-level @prepare() for all of them.
+ *
+ * @freeze_late: Continue operations started by @freeze().  Analogous to
+ *	@suspend_late(), but it should not enable the device to signal wakeup
+ *	events or change its power state.
+ *
+ * @thaw: Hibernation-specific, executed after creating a hibernation image OR
+ *	if the creation of an image has failed.  Also executed after a failing
+ *	attempt to restore the contents of main memory from such an image.
+ *	Undo the changes made by the preceding @freeze(), so the device can be
+ *	operated in the same way as immediately before the call to @freeze().
+ *	Subsystem-level @thaw() is executed for all devices after invoking
+ *	subsystem-level @thaw_noirq() for all of them.  It also may be executed
+ *	directly after @freeze() in case of a transition error.
+ *
+ * @thaw_early: Prepare to execute @thaw().  Undo the changes made by the
+ *	preceding @freeze_late().
+ *
+ * @poweroff: Hibernation-specific, executed after saving a hibernation image.
+ *	Analogous to @suspend(), but it need not save the device's settings in
+ *	memory.
+ *	Subsystem-level @poweroff() is executed for all devices after invoking
+ *	subsystem-level @prepare() for all of them.
+ *
+ * @poweroff_late: Continue operations started by @poweroff().  Analogous to
+ *	@suspend_late(), but it need not save the device's settings in memory.
+ *
+ * @restore: Hibernation-specific, executed after restoring the contents of main
+ *	memory from a hibernation image, analogous to @resume().
+ *
+ * @restore_early: Prepare to execute @restore(), analogous to @resume_early().
+ *
+ * @suspend_noirq: Complete the actions started by @suspend().  Carry out any
+ *	additional operations required for suspending the device that might be
+ *	racing with its driver's interrupt handler, which is guaranteed not to
+ *	run while @suspend_noirq() is being executed.
+ *	It generally is expected that the device will be in a low-power state
+ *	(appropriate for the target system sleep state) after subsystem-level
+ *	@suspend_noirq() has returned successfully.  If the device can generate
+ *	system wakeup signals and is enabled to wake up the system, it should be
+ *	configured to do so at that time.  However, depending on the platform
+ *	and device's subsystem, @suspend() or @suspend_late() may be allowed to
+ *	put the device into the low-power state and configure it to generate
+ *	wakeup signals, in which case it generally is not necessary to define
+ *	@suspend_noirq().
+ *
+ * @resume_noirq: Prepare for the execution of @resume() by carrying out any
+ *	operations required for resuming the device that might be racing with
+ *	its driver's interrupt handler, which is guaranteed not to run while
+ *	@resume_noirq() is being executed.
+ *
+ * @freeze_noirq: Complete the actions started by @freeze().  Carry out any
+ *	additional operations required for freezing the device that might be
+ *	racing with its driver's interrupt handler, which is guaranteed not to
+ *	run while @freeze_noirq() is being executed.
+ *	The power state of the device should not be changed by either @freeze(),
+ *	or @freeze_late(), or @freeze_noirq() and it should not be configured to
+ *	signal system wakeup by any of these callbacks.
+ *
+ * @thaw_noirq: Prepare for the execution of @thaw() by carrying out any
+ *	operations required for thawing the device that might be racing with its
+ *	driver's interrupt handler, which is guaranteed not to run while
+ *	@thaw_noirq() is being executed.
+ *
+ * @poweroff_noirq: Complete the actions started by @poweroff().  Analogous to
+ *	@suspend_noirq(), but it need not save the device's settings in memory.
+ *
+ * @restore_noirq: Prepare for the execution of @restore() by carrying out any
+ *	operations required for thawing the device that might be racing with its
+ *	driver's interrupt handler, which is guaranteed not to run while
+ *	@restore_noirq() is being executed.  Analogous to @resume_noirq().
+ *
+ * All of the above callbacks, except for @complete(), return error codes.
+ * However, the error codes returned by the resume operations, @resume(),
+ * @thaw(), @restore(), @resume_noirq(), @thaw_noirq(), and @restore_noirq(), do
+ * not cause the PM core to abort the resume transition during which they are
+ * returned.  The error codes returned in those cases are only printed by the PM
+ * core to the system logs for debugging purposes.  Still, it is recommended
+ * that drivers only return error codes from their resume methods in case of an
+ * unrecoverable failure (i.e. when the device being handled refuses to resume
+ * and becomes unusable) to allow us to modify the PM core in the future, so
+ * that it can avoid attempting to handle devices that failed to resume and
+ * their children.
+ *
+ * It is allowed to unregister devices while the above callbacks are being
+ * executed.  However, a callback routine must NOT try to unregister the device
+ * it was called for, although it may unregister children of that device (for
+ * example, if it detects that a child was unplugged while the system was
+ * asleep).
+ *
+ * Refer to Documentation/power/devices.txt for more information about the role
+ * of the above callbacks in the system suspend process.
+ *
+ * There also are callbacks related to runtime power management of devices.
+ * Again, these callbacks are executed by the PM core only for subsystems
+ * (PM domains, device types, classes and bus types) and the subsystem-level
+ * callbacks are supposed to invoke the driver callbacks.  Moreover, the exact
+ * actions to be performed by a device driver's callbacks generally depend on
+ * the platform and subsystem the device belongs to.
+ *
+ * @runtime_suspend: Prepare the device for a condition in which it won't be
+ *	able to communicate with the CPU(s) and RAM due to power management.
+ *	This need not mean that the device should be put into a low-power state.
+ *	For example, if the device is behind a link which is about to be turned
+ *	off, the device may remain at full power.  If the device does go to low
+ *	power and is capable of generating runtime wakeup events, remote wakeup
+ *	(i.e., a hardware mechanism allowing the device to request a change of
+ *	its power state via an interrupt) should be enabled for it.
+ *
+ * @runtime_resume: Put the device into the fully active state in response to a
+ *	wakeup event generated by hardware or at the request of software.  If
+ *	necessary, put the device into the full-power state and restore its
+ *	registers, so that it is fully operational.
+ *
+ * @runtime_idle: Device appears to be inactive and it might be put into a
+ *	low-power state if all of the necessary conditions are satisfied.
+ *	Check these conditions, and return 0 if it's appropriate to let the PM
+ *	core queue a suspend request for the device.
+ *
+ * Refer to Documentation/power/runtime_pm.txt for more information about the
+ * role of the above callbacks in device runtime power management.

+/**
+ * Radix-tree synchronization
+ *
+ * The radix-tree API requires that users provide all synchronisation (with
+ * specific exceptions, noted below).
+ *
+ * Synchronization of access to the data items being stored in the tree, and
+ * management of their lifetimes must be completely managed by API users.
+ *
+ * For API usage, in general,
+ * - any function _modifying_ the tree or tags (inserting or deleting
+ *   items, setting or clearing tags) must exclude other modifications, and
+ *   exclude any functions reading the tree.
+ * - any function _reading_ the tree or tags (looking up items or tags,
+ *   gang lookups) must exclude modifications to the tree, but may occur
+ *   concurrently with other readers.
+ *
+ * The notable exceptions to this rule are the following functions:
+ * __radix_tree_lookup
+ * radix_tree_lookup
+ * radix_tree_lookup_slot
+ * radix_tree_tag_get
+ * radix_tree_gang_lookup
+ * radix_tree_gang_lookup_slot
+ * radix_tree_gang_lookup_tag
+ * radix_tree_gang_lookup_tag_slot
+ * radix_tree_tagged
+ *
+ * The first 7 functions are able to be called locklessly, using RCU. The
+ * caller must ensure calls to these functions are made within rcu_read_lock()
+ * regions. Other readers (lock-free or otherwise) and modifications may be
+ * running concurrently.
+ *
+ * It is still required that the caller manage the synchronization and lifetimes
+ * of the items. So if RCU lock-free lookups are used, typically this would mean
+ * that the items have their own locks, or are amenable to lock-free access; and
+ * that the items are freed by RCU (or only freed after having been deleted from
+ * the radix tree *and* a synchronize_rcu() grace period).
+ *
+ * (Note, rcu_assign_pointer and rcu_dereference are not needed to control
+ * access to data items when inserting into or looking up from the radix tree)
+ *
+ * Note that the value returned by radix_tree_tag_get() may not be relied upon
+ * if only the RCU read lock is held.  Functions to set/clear tags and to
+ * delete nodes running concurrently with it may affect its result such that
+ * two consecutive reads in the same locked section may return different
+ * values.  If reliability is required, modification functions must also be
+ * excluded from concurrency.
+ *
+ * radix_tree_tagged is able to be called without locking or RCU.

+ *
+ * Note that all CPUs must agree that the grace period extended beyond
+ * all pre-existing RCU read-side critical section.  On systems with more
+ * than one CPU, this means that when "func()" is invoked, each CPU is
+ * guaranteed to have executed a full memory barrier since the end of its
+ * last RCU read-side critical section whose beginning preceded the call
+ * to call_rcu().  It also means that each CPU executing an RCU read-side
+ * critical section that continues beyond the start of "func()" must have
+ * executed a memory barrier after the call_rcu() but before the beginning
+ * of that RCU read-side critical section.  Note that these guarantees
+ * include CPUs that are offline, idle, or executing in user mode, as
+ * well as CPUs that are executing in the kernel.
+ *
+ * Furthermore, if CPU A invoked call_rcu() and CPU B invoked the
+ * resulting RCU callback function "func()", then both CPU A and CPU B are
+ * guaranteed to execute a full memory barrier during the time interval
+ * between the call to call_rcu() and the invocation of "func()" -- even

+ *
+ * That said, RCU readers are never priority boosted unless they were

+ * section whose outermost rcu_read_unlock() is called with one of

+ *
+ * @writeable_reg: Optional callback returning true if the register
+ *		   can be written to. If this field is NULL but wr_table
+ *		   (see below) is not, the check is performed on such table
+ *                 (a register is writeable if it belongs to one of the ranges

+ *		  volatile_table (see below) is not, the check is performed on
+ *                such table (a register is volatile if it belongs to one of
+ *                the ranges specified by volatile_table).
+ * @precious_reg: Optional callback returning true if the register
+ *		  should not be read outside of a call from the driver
+ *		  (e.g., a clear on read interrupt status register). If this
+ *                field is NULL but precious_table (see below) is not, the
+ *                check is performed on such table (a register is precious if
+ *                it belongs to one of the ranges specified by precious_table).
+ * @lock:	  Optional lock callback (overrides regmap's default lock
+ *		  function, based on spinlock or mutex).
+ * @unlock:	  As above for unlocking.
+ * @lock_arg:	  this field is passed as the only argument of lock/unlock
+ *		  functions (ignored in case regular lock/unlock functions
+ *		  are not overridden).
+ * @reg_read:	  Optional callback that if filled will be used to perform
+ *           	  all the reads from the registers. Should only be provided for
+ *		  devices whose read operation cannot be represented as a simple
+ *		  read operation on a bus such as SPI, I2C, etc. Most of the
+ *		  devices do not need this.
+ * @reg_write:	  Same as above for writing.
+ * @fast_io:	  Register IO is fast. Use a spinlock instead of a mutex
+ *	     	  to perform locking. This field is ignored if custom lock/unlock
+ *	     	  functions are used (see fields lock/unlock of struct regmap_config).
+ *		  This field is a duplicate of a similar file in
+ *		  'struct regmap_bus' and serves exact same purpose.
+ *		   Use it only for "no-bus" cases.
+ * @max_register: Optional, specifies the maximum valid register index.
+ * @wr_table:     Optional, points to a struct regmap_access_table specifying
+ *                valid ranges for write access.
+ * @rd_table:     As above, for read access.
+ * @volatile_table: As above, for volatile registers.
+ * @precious_table: As above, for precious registers.
+ * @reg_defaults: Power on reset values for registers (for use with
+ *                register cache support).
+ * @num_reg_defaults: Number of elements in reg_defaults.
+ *
+ * @read_flag_mask: Mask to be set in the top byte of the register when doing
+ *                  a read.
+ * @write_flag_mask: Mask to be set in the top byte of the register when doing
+ *                   a write. If both read_flag_mask and write_flag_mask are
+ *                   empty the regmap_bus default masks are used.
+ * @use_single_rw: If set, converts the bulk read and write operations into
+ *		    a series of single read and write operations. This is useful
+ *		    for device that does not support bulk read and write.
+ * @can_multi_write: If set, the device supports the multi write mode of bulk

+ * @core_note_type:	ELF note @n_type value used in core dumps.
+ * @get:		Function to fetch values.

+ * @active:		Function to report if regset is active, or %NULL.
+ * @writeback:		Function to write data back to user memory, or %NULL.
+ *
+ * This data structure describes a machine resource we call a register set.
+ * This is part of the state of an individual thread, not necessarily
+ * actual CPU registers per se.  A register set consists of a number of
+ * similar slots, given by @n.  Each slot is @size bytes, and aligned to
+ * @align bytes (which is at least @size).
+ *
+ * These functions must be called only on the current thread or on a
+ * thread that is in %TASK_STOPPED or %TASK_TRACED state, that we are
+ * guaranteed will not be woken up and return to user mode, and that we
+ * have called wait_task_inactive() on.  (The target thread always might
+ * wake up for SIGKILL while these functions are working, in which case
+ * that thread's user_regset state might be scrambled.)
+ *
+ * The @pos argument must be aligned according to @align; the @count
+ * argument must be a multiple of @size.  These functions are not
+ * responsible for checking for invalid arguments.
+ *
+ * When there is a natural value to use as an index, @bias gives the
+ * difference between the natural index and the slot index for the
+ * register set.  For example, x86 GDT segment descriptors form a regset;
+ * the segment selector produces a natural index, but only a subset of
+ * that index space is available as a regset (the TLS slots); subtracting
+ * @bias from a segment selector index value computes the regset slot.
+ *
+ * If nonzero, @core_note_type gives the n_type field (NT_* value)
+ * of the core file note in which this regset's data appears.
+ * NT_PRSTATUS is a special case in that the regset data starts at
+ * offsetof(struct elf_prstatus, pr_reg) into the note data; that is
+ * part of the per-machine ELF formats userland knows about.  In

+ *
+ * EXPERIMENTAL FEATURES:
+ *   Dynamic Regulator operating Mode Switching (DRMS) - allows regulators
+ *   to use most efficient operating mode depending upon voltage and load and
+ *   is transparent to client drivers.
+ *
+ *   e.g. Devices x,y,z share regulator r. Device x and y draw 20mA each during
+ *   IO and 1mA at idle. Device z draws 100mA when under load and 5mA when
+ *   idling. Regulator r has > 90% efficiency in NORMAL mode at loads > 100mA
+ *   but this drops rapidly to 60% when below 100mA. Regulator r has > 90%
+ *   efficiency in IDLE mode at loads < 10mA. Thus regulator r will operate
+ *   in normal mode for loads > 10mA and in IDLE mode for load <= 10mA.

+ * Regulator operating modes.
+ *
+ * Regulators can run in a variety of different operating modes depending on
+ * output load. This allows further system power savings by selecting the
+ * best (and most efficient) regulator mode for a desired load.
+ *
+ * Most drivers will only care about NORMAL. The modes below are generic and
+ * will probably not match the naming convention of your regulator data sheet
+ * but should match the use cases in the datasheet.
+ *
+ * In order of power efficiency (least efficient at top).
+ *
+ *  Mode       Description
+ *  FAST       Regulator can handle fast changes in it's load.
+ *             e.g. useful in CPU voltage & frequency scaling where
+ *             load can quickly increase with CPU frequency increases.
+ *
+ *  NORMAL     Normal regulator power supply mode. Most drivers will
+ *             use this mode.
+ *
+ *  IDLE       Regulator runs in a more efficient mode for light
+ *             loads. Can be used for devices that have a low power
+ *             requirement during periods of inactivity. This mode
+ *             may be more noisy than NORMAL and may not be able
+ *             to handle fast load switching.
+ *
+ *  STANDBY    Regulator runs in the most efficient mode for very
+ *             light loads. Can be used by devices when they are
+ *             in a sleep/standby state. This mode is likely to be
+ *             the most noisy and may not be able to handle fast load
+ *             switching.
+ *
+ * NOTE: Most regulators will only support a subset of these modes. Some
+ * will only just support NORMAL.
+ *
+ * These modes can be OR'ed together to make up a mask of valid register modes.

+ * Extended scheduling parameters data structure.
+ *
+ * This is needed because the original struct sched_param can not be
+ * altered without introducing ABI issues with legacy applications
+ * (e.g., in sched_getparam()).
+ *
+ * However, the possibility of specifying more than just a priority for
+ * the tasks may be useful for a wide variety of application fields, e.g.,
+ * multimedia, streaming, automation and control, and many others.
+ *
+ * This variant (sched_attr) is meant at describing a so-called
+ * sporadic time-constrained task. In such model a task is specified by:
+ *  - the activation period or minimum instance inter-arrival time;
+ *  - the maximum (or average, depending on the actual scheduling
+ *    discipline) computation time of all instances, a.k.a. runtime;
+ *  - the deadline (relative to the actual activation time) of each
+ *    instance.
+ * Very briefly, a periodic (sporadic) task asks for the execution of
+ * some specific computation --which is typically called an instance--
+ * (at most) every period. Moreover, each instance typically lasts no more
+ * than the runtime and must be completed by time instant t equal to
+ * the instance activation time + the deadline.
+ *
+ * This is reflected by the actual fields of the sched_attr structure:
+ *
+ *  @size		size of the structure, for fwd/bwd compat.
+ *
+ *  @sched_policy	task's scheduling policy
+ *  @sched_flags	for customizing the scheduler behaviour
+ *  @sched_nice		task's nice value      (SCHED_NORMAL/BATCH)
+ *  @sched_priority	task's static priority (SCHED_FIFO/RR)
+ *  @sched_deadline	representative of the task's deadline
+ *  @sched_runtime	representative of the task's runtime
+ *  @sched_period	representative of the task's period
+ *
+ * Given this task model, there are a multiplicity of scheduling algorithms
+ * and policies, that can be used to ensure all the tasks will make their
+ * timing constraints.
+ *
+ * As of now, the SCHED_DEADLINE policy (sched_dl scheduling class) is the
+ * only user of this new interface. More information about the algorithm
+ * available in the scheduling class file or in Documentation/.

+/**
+ * struct security_operations - main security structure
+ *
+ * Security module identifier.
+ *
+ * @name:
+ *	A string that acts as a unique identifier for the LSM with max number
+ *	of characters = SECURITY_NAME_MAX.
+ *
+ * Security hooks for program execution operations.
+ *
+ * @bprm_set_creds:
+ *	Save security information in the bprm->security field, typically based
+ *	on information about the bprm->file, for later use by the apply_creds
+ *	hook.  This hook may also optionally check permissions (e.g. for
+ *	transitions between security domains).
+ *	This hook may be called multiple times during a single execve, e.g. for
+ *	interpreters.  The hook can tell whether it has already been called by
+ *	checking to see if @bprm->security is non-NULL.  If so, then the hook
+ *	may decide either to retain the security information saved earlier or
+ *	to replace it.
+ *	@bprm contains the linux_binprm structure.
+ *	Return 0 if the hook is successful and permission is granted.
+ * @bprm_check_security:
+ *	This hook mediates the point when a search for a binary handler will
+ *	begin.  It allows a check the @bprm->security value which is set in the
+ *	preceding set_creds call.  The primary difference from set_creds is
+ *	that the argv list and envp list are reliably available in @bprm.  This
+ *	hook may be called multiple times during a single execve; and in each
+ *	pass set_creds is called first.
+ *	@bprm contains the linux_binprm structure.
+ *	Return 0 if the hook is successful and permission is granted.
+ * @bprm_committing_creds:
+ *	Prepare to install the new security attributes of a process being
+ *	transformed by an execve operation, based on the old credentials
+ *	pointed to by @current->cred and the information set in @bprm->cred by
+ *	the bprm_set_creds hook.  @bprm points to the linux_binprm structure.
+ *	This hook is a good place to perform state changes on the process such
+ *	as closing open file descriptors to which access will no longer be
+ *	granted when the attributes are changed.  This is called immediately
+ *	before commit_creds().
+ * @bprm_committed_creds:
+ *	Tidy up after the installation of the new security attributes of a
+ *	process being transformed by an execve operation.  The new credentials
+ *	have, by this point, been set to @current->cred.  @bprm points to the
+ *	linux_binprm structure.  This hook is a good place to perform state
+ *	changes on the process such as clearing out non-inheritable signal
+ *	state.  This is called immediately after commit_creds().
+ * @bprm_secureexec:
+ *	Return a boolean value (0 or 1) indicating whether a "secure exec"
+ *	is required.  The flag is passed in the auxiliary table
+ *	on the initial stack to the ELF interpreter to indicate whether libc
+ *	should enable secure mode.
+ *	@bprm contains the linux_binprm structure.
+ *
+ * Security hooks for filesystem operations.
+ *
+ * @sb_alloc_security:
+ *	Allocate and attach a security structure to the sb->s_security field.
+ *	The s_security field is initialized to NULL when the structure is
+ *	allocated.
+ *	@sb contains the super_block structure to be modified.
+ *	Return 0 if operation was successful.
+ * @sb_free_security:
+ *	Deallocate and clear the sb->s_security field.
+ *	@sb contains the super_block structure to be modified.
+ * @sb_statfs:
+ *	Check permission before obtaining filesystem statistics for the @mnt
+ *	mountpoint.
+ *	@dentry is a handle on the superblock for the filesystem.
+ *	Return 0 if permission is granted.
+ * @sb_mount:
+ *	Check permission before an object specified by @dev_name is mounted on
+ *	the mount point named by @nd.  For an ordinary mount, @dev_name
+ *	identifies a device if the file system type requires a device.  For a
+ *	remount (@flags & MS_REMOUNT), @dev_name is irrelevant.  For a
+ *	loopback/bind mount (@flags & MS_BIND), @dev_name identifies the
+ *	pathname of the object being mounted.
+ *	@dev_name contains the name for object being mounted.
+ *	@path contains the path for mount point object.
+ *	@type contains the filesystem type.
+ *	@flags contains the mount flags.
+ *	@data contains the filesystem-specific data.
+ *	Return 0 if permission is granted.
+ * @sb_copy_data:
+ *	Allow mount option data to be copied prior to parsing by the filesystem,
+ *	so that the security module can extract security-specific mount
+ *	options cleanly (a filesystem may modify the data e.g. with strsep()).
+ *	This also allows the original mount data to be stripped of security-
+ *	specific options to avoid having to make filesystems aware of them.
+ *	@type the type of filesystem being mounted.
+ *	@orig the original mount data copied from userspace.
+ *	@copy copied data which will be passed to the security module.
+ *	Returns 0 if the copy was successful.
+ * @sb_remount:
+ *	Extracts security system specific mount options and verifies no changes
+ *	are being made to those options.
+ *	@sb superblock being remounted
+ *	@data contains the filesystem-specific data.
+ *	Return 0 if permission is granted.
+ * @sb_umount:
+ *	Check permission before the @mnt file system is unmounted.
+ *	@mnt contains the mounted file system.
+ *	@flags contains the unmount flags, e.g. MNT_FORCE.
+ *	Return 0 if permission is granted.
+ * @sb_pivotroot:
+ *	Check permission before pivoting the root filesystem.
+ *	@old_path contains the path for the new location of the current root (put_old).
+ *	@new_path contains the path for the new root (new_root).
+ *	Return 0 if permission is granted.
+ * @sb_set_mnt_opts:
+ *	Set the security relevant mount options used for a superblock
+ *	@sb the superblock to set security mount options for
+ *	@opts binary data structure containing all lsm mount data
+ * @sb_clone_mnt_opts:
+ *	Copy all security options from a given superblock to another
+ *	@oldsb old superblock which contain information to clone
+ *	@newsb new superblock which needs filled in
+ * @sb_parse_opts_str:
+ *	Parse a string of security data filling in the opts structure
+ *	@options string containing all mount options known by the LSM
+ *	@opts binary data structure usable by the LSM
+ * @dentry_init_security:
+ *	Compute a context for a dentry as the inode is not yet available
+ *	since NFSv4 has no label backed by an EA anyway.
+ *	@dentry dentry to use in calculating the context.
+ *	@mode mode used to determine resource type.
+ *	@name name of the last path component used to create file
+ *	@ctx pointer to place the pointer to the resulting context in.
+ *	@ctxlen point to place the length of the resulting context.
+ *
+ *
+ * Security hooks for inode operations.
+ *
+ * @inode_alloc_security:
+ *	Allocate and attach a security structure to @inode->i_security.  The
+ *	i_security field is initialized to NULL when the inode structure is
+ *	allocated.
+ *	@inode contains the inode structure.
+ *	Return 0 if operation was successful.
+ * @inode_free_security:
+ *	@inode contains the inode structure.
+ *	Deallocate the inode security structure and set @inode->i_security to
+ *	NULL.
+ * @inode_init_security:
+ *	Obtain the security attribute name suffix and value to set on a newly
+ *	created inode and set up the incore security field for the new inode.
+ *	This hook is called by the fs code as part of the inode creation
+ *	transaction and provides for atomic labeling of the inode, unlike
+ *	the post_create/mkdir/... hooks called by the VFS.  The hook function
+ *	is expected to allocate the name and value via kmalloc, with the caller
+ *	being responsible for calling kfree after using them.
+ *	If the security module does not use security attributes or does
+ *	not wish to put a security attribute on this particular inode,
+ *	then it should return -EOPNOTSUPP to skip this processing.
+ *	@inode contains the inode structure of the newly created inode.
+ *	@dir contains the inode structure of the parent directory.
+ *	@qstr contains the last path component of the new object
+ *	@name will be set to the allocated name suffix (e.g. selinux).
+ *	@value will be set to the allocated attribute value.
+ *	@len will be set to the length of the value.
+ *	Returns 0 if @name and @value have been successfully set,
+ *		-EOPNOTSUPP if no security attribute is needed, or
+ *		-ENOMEM on memory allocation failure.
+ * @inode_create:
+ *	Check permission to create a regular file.
+ *	@dir contains inode structure of the parent of the new file.
+ *	@dentry contains the dentry structure for the file to be created.
+ *	@mode contains the file mode of the file to be created.
+ *	Return 0 if permission is granted.
+ * @inode_link:
+ *	Check permission before creating a new hard link to a file.
+ *	@old_dentry contains the dentry structure for an existing link to the file.
+ *	@dir contains the inode structure of the parent directory of the new link.
+ *	@new_dentry contains the dentry structure for the new link.
+ *	Return 0 if permission is granted.
+ * @path_link:
+ *	Check permission before creating a new hard link to a file.
+ *	@old_dentry contains the dentry structure for an existing link
+ *	to the file.
+ *	@new_dir contains the path structure of the parent directory of
+ *	the new link.
+ *	@new_dentry contains the dentry structure for the new link.
+ *	Return 0 if permission is granted.
+ * @inode_unlink:
+ *	Check the permission to remove a hard link to a file.
+ *	@dir contains the inode structure of parent directory of the file.
+ *	@dentry contains the dentry structure for file to be unlinked.
+ *	Return 0 if permission is granted.
+ * @path_unlink:
+ *	Check the permission to remove a hard link to a file.
+ *	@dir contains the path structure of parent directory of the file.

+ * Security hooks for file operations
+ *
+ * @file_permission:

+ *    Writers do not wait for a sequence reader.

+ *    is in progress. A locking reader in progress will also block a writer
+ *    from going forward. Unlike the regular rwlock, the read lock here is
+ *    exclusive so that only one locking reader can get it.
+ *
+ * This is not as cache friendly as brlock. Also, this may not work well
+ * for data that contains pointers, because any writer could
+ * invalidate a pointer that a reader was following.

+ *
+ * Certain hardware have instructions to insert this type of wait condition
+ * in the command stream, so no intervention from software would be needed.
+ * This type of fence can be destroyed before completed, however a reference
+ * on the sync_buf dma-buf can be taken. It is encouraged to re-use the same
+ * dma-buf for sync_buf, since mapping or unmapping the sync_buf to the
+ * device's vm can be expensive.
+ *
+ * It is recommended for creators of seqno_fence to call fence_signal
+ * before destruction. This will prevent possible issues from wraparound at
+ * time of issue vs time of check, since users can check fence_is_signaled
+ * before submitting instructions for the hardware to wait on the fence.
+ * However, when ops.enable_signaling is not called, it doesn't have to be

+ * from being delivered until later.  When the signal is delivered,
+ * either it's caught or ignored by a user handler or it has a default
+ * effect that applies to the whole thread group (POSIX process).
+ *
+ * The possible effects an unblocked signal set to SIG_DFL can have are:
+ *   ignore	- Nothing Happens
+ *   terminate	- kill the process, i.e. all threads in the group,
+ * 		  similar to exit_group.  The group leader (only) reports
+ *		  WIFSIGNALED status to its parent.
+ *   coredump	- write a core dump file describing all threads using
+ *		  the same mm and then kill all those threads
+ *   stop 	- stop all the threads in the group, i.e. TASK_STOPPED state
+ *
+ * SIGKILL and SIGSTOP cannot be caught, blocked, or ignored.
+ * Other signals when not blocked and set to SIG_DFL behaves as follows.
+ * The job control signals also have other special effects.

+/* A. Checksumming of received packets by device.
+ *
+ * CHECKSUM_NONE:
+ *
+ *   Device failed to checksum this packet e.g. due to lack of capabilities.
+ *   The packet contains full (though not verified) checksum in packet but
+ *   not in skb->csum. Thus, skb->csum is undefined in this case.
+ *
+ * CHECKSUM_UNNECESSARY:
+ *
+ *   The hardware you're dealing with doesn't calculate the full checksum
+ *   (as in CHECKSUM_COMPLETE), but it does parse headers and verify checksums
+ *   for specific protocols. For such packets it will set CHECKSUM_UNNECESSARY
+ *   if their checksums are okay. skb->csum is still undefined in this case
+ *   though. It is a bad option, but, unfortunately, nowadays most vendors do
+ *   this. Apparently with the secret goal to sell you new devices, when you
+ *   will add new protocol to your host, f.e. IPv6 8)
+ *
+ *   CHECKSUM_UNNECESSARY is applicable to following protocols:
+ *     TCP: IPv6 and IPv4.
+ *     UDP: IPv4 and IPv6. A device may apply CHECKSUM_UNNECESSARY to a
+ *       zero UDP checksum for either IPv4 or IPv6, the networking stack
+ *       may perform further validation in this case.
+ *     GRE: only if the checksum is present in the header.
+ *     SCTP: indicates the CRC in SCTP header has been validated.
+ *
+ *   skb->csum_level indicates the number of consecutive checksums found in
+ *   the packet minus one that have been verified as CHECKSUM_UNNECESSARY.
+ *   For instance if a device receives an IPv6->UDP->GRE->IPv4->TCP packet
+ *   and a device is able to verify the checksums for UDP (possibly zero),
+ *   GRE (checksum flag is set), and TCP-- skb->csum_level would be set to
+ *   two. If the device were only able to verify the UDP checksum and not
+ *   GRE, either because it doesn't support GRE checksum of because GRE
+ *   checksum is bad, skb->csum_level would be set to zero (TCP checksum is
+ *   not considered in this case).
+ *
+ * CHECKSUM_COMPLETE:
+ *
+ *   This is the most generic way. The device supplied checksum of the _whole_
+ *   packet as seen by netif_rx() and fills out in skb->csum. Meaning, the
+ *   hardware doesn't need to parse L3/L4 headers to implement this.
+ *
+ *   Note: Even if device supports only some protocols, but is able to produce
+ *   skb->csum, it MUST use CHECKSUM_COMPLETE, not CHECKSUM_UNNECESSARY.
+ *
+ * CHECKSUM_PARTIAL:
+ *
+ *   A checksum is set up to be offloaded to a device as described in the
+ *   output description for CHECKSUM_PARTIAL. This may occur on a packet
+ *   received directly from another Linux OS, e.g., a virtualized Linux kernel
+ *   on the same host, or it may be set in the input path in GRO or remote
+ *   checksum offload. For the purposes of checksum verification, the checksum
+ *   referred to by skb->csum_start + skb->csum_offset and any preceding
+ *   checksums in the packet are considered verified. Any checksums in the
+ *   packet that are after the checksum being offloaded are not considered to
+ *   be verified.
+ *
+ * B. Checksumming on output.
+ *
+ * CHECKSUM_NONE:
+ *
+ *   The skb was already checksummed by the protocol, or a checksum is not
+ *   required.
+ *
+ * CHECKSUM_PARTIAL:
+ *
+ *   The device is required to checksum the packet as seen by hard_start_xmit()
+ *   from skb->csum_start up to the end, and to record/write the checksum at
+ *   offset skb->csum_start + skb->csum_offset.
+ *
+ *   The device must show its capabilities in dev->features, set up at device
+ *   setup time, e.g. netdev_features.h:
+ *
+ *	NETIF_F_HW_CSUM	- It's a clever device, it's able to checksum everything.
+ *	NETIF_F_IP_CSUM - Device is dumb, it's able to checksum only TCP/UDP over
+ *			  IPv4. Sigh. Vendors like this way for an unknown reason.
+ *			  Though, see comment above about CHECKSUM_UNNECESSARY. 8)
+ *	NETIF_F_IPV6_CSUM - About as dumb as the last one but does IPv6 instead.
+ *	NETIF_F_...     - Well, you get the picture.
+ *
+ * CHECKSUM_UNNECESSARY:
+ *
+ *   Normally, the device will do per protocol specific checksumming. Protocol
+ *   implementations that do not want the NIC to perform the checksum
+ *   calculation should use this flag in their outgoing skbs.
+ *
+ *	NETIF_F_FCOE_CRC - This indicates that the device can do FCoE FC CRC
+ *			   offload. Correspondingly, the FCoE protocol driver
+ *			   stack should use CHECKSUM_UNNECESSARY.
+ *
+ * Any questions? No questions, good.		--ANK

+ * kmalloc - allocate memory
+ * @size: how many bytes of memory are required.
+ * @flags: the type of memory to allocate.
+ *
+ * kmalloc is the normal method of allocating memory
+ * for objects smaller than page size in the kernel.
+ *
+ * The @flags argument may be one of:
+ *
+ * %GFP_USER - Allocate memory on behalf of user.  May sleep.
+ *
+ * %GFP_KERNEL - Allocate normal kernel ram.  May sleep.
+ *
+ * %GFP_ATOMIC - Allocation will not sleep.  May use emergency pools.
+ *   For example, use this inside interrupt handlers.
+ *
+ * %GFP_HIGHUSER - Allocate pages from high memory.
+ *
+ * %GFP_NOIO - Do not do any I/O at all while trying to get memory.
+ *
+ * %GFP_NOFS - Do not make any fs calls while trying to get memory.
+ *
+ * %GFP_NOWAIT - Allocation will not sleep.
+ *
+ * %__GFP_THISNODE - Allocate node-local memory only.
+ *
+ * %GFP_DMA - Allocation suitable for DMA.
+ *   Should only be used for kmalloc() caches. Otherwise, use a
+ *   slab created with SLAB_DMA.
+ *
+ * Also it is possible to set different flags by OR'ing
+ * in one or more of the following additional @flags:
+ *
+ * %__GFP_COLD - Request cache-cold pages instead of
+ *   trying to return cache-warm pages.
+ *
+ * %__GFP_HIGH - This allocation has high priority and may use emergency pools.
+ *
+ * %__GFP_NOFAIL - Indicate that this allocation is in no way allowed to fail
+ *   (think twice before using).
+ *
+ * %__GFP_NORETRY - If memory is not immediately available,
+ *   then give up at once.
+ *
+ * %__GFP_NOWARN - If allocation fails, don't issue any warnings.
+ *
+ * %__GFP_REPEAT - If allocation fails initially, try once more before failing.
+ *
+ * There are other flags available as well, but these are not intended
+ * for general use, and so are not documented here. For a full list of

+ * @tx_sg: Scatterlist for transmit, currently not for client use
+ * @rx_sg: Scatterlist for receive, currently not for client use
+ *
+ * SPI transfers always write the same number of bytes as they read.
+ * Protocol drivers should always provide @rx_buf and/or @tx_buf.
+ * In some cases, they may also want to provide DMA addresses for
+ * the data being transferred; that may reduce overhead, when the
+ * underlying driver uses dma.
+ *
+ * If the transmit buffer is null, zeroes will be shifted out
+ * while filling @rx_buf.  If the receive buffer is null, the data
+ * shifted in will be discarded.  Only "len" bytes shift out (or in).
+ * It's an error to try to shift out a partial word.  (For example, by
+ * shifting out three bytes with word size of sixteen or twenty bits;
+ * the former uses two bytes per word, the latter uses four bytes.)
+ *
+ * In-memory data values are always in native CPU byte order, translated
+ * from the wire byte order (big-endian except with SPI_LSB_FIRST).  So
+ * for example when bits_per_word is sixteen, buffers are 2N bytes long
+ * (@len = 2N) and hold N sixteen bit words in CPU byte order.
+ *
+ * When the word size of the SPI transfer is not a power-of-two multiple
+ * of eight bits, those in-memory words include extra bits.  In-memory
+ * words are always seen by protocol drivers as right-justified, so the
+ * undefined (rx) or unused (tx) bits are always the most significant bits.
+ *
+ * All SPI transfers start with the relevant chipselect active.  Normally
+ * it stays selected until after the last transfer in a message.  Drivers
+ * can affect the chipselect signal using cs_change.
+ *
+ * (i) If the transfer isn't the last one in the message, this flag is
+ * used to make the chipselect briefly go inactive in the middle of the
+ * message.  Toggling chipselect in this way may be needed to terminate
+ * a chip command, letting a single spi_message perform all of group of
+ * chip transactions together.
+ *
+ * (ii) When the transfer is the last one in the message, the chip may
+ * stay selected until the next transfer.  On multi-device SPI busses
+ * with nothing blocking messages going to other devices, this is just
+ * a performance hint; starting a message to another device deselects
+ * this one.  But in other cases, this can be used to ensure correctness.
+ * Some devices need protocol transactions to be built from a series of
+ * spi_message submissions, where the content of one message is determined
+ * by the results of previous messages and where the whole transaction
+ * ends when the chipselect goes intactive.
+ *
+ * When SPI can transfer in 1x,2x or 4x. It can get this transfer information
+ * from device through @tx_nbits and @rx_nbits. In Bi-direction, these
+ * two should both be set. User can set transfer mode with SPI_NBITS_SINGLE(1x)
+ * SPI_NBITS_DUAL(2x) and SPI_NBITS_QUAD(4x) to support these three transfer.
+ *
+ * The code that submits an spi_message (and its spi_transfers)
+ * to the lower layers is responsible for managing its memory.

+ *
+ * here's the role of the various spinlock/rwlock related include files:
+ *
+ * on SMP builds:
+ *
+ *  asm/spinlock_types.h: contains the arch_spinlock_t/arch_rwlock_t and the
+ *                        initializers
+ *
+ *  linux/spinlock_types.h:
+ *                        defines the generic type and initializers
+ *
+ *  asm/spinlock.h:       contains the arch_spin_*()/etc. lowlevel
+ *                        implementations, mostly inline assembly code
+ *
+ *   (also included on UP-debug builds:)
+ *
+ *  linux/spinlock_api_smp.h:
+ *                        contains the prototypes for the _spin_*() APIs.
+ *
+ *  linux/spinlock.h:     builds the final spin_*() APIs.
+ *
+ * on UP builds:
+ *
+ *  linux/spinlock_type_up.h:
+ *                        contains the generic, simplified UP spinlock type.
+ *                        (which is an empty structure on non-debug builds)
+ *
+ *  linux/spinlock_types.h:
+ *                        defines the generic type and initializers
+ *
+ *  linux/spinlock_up.h:
+ *                        contains the arch_spin_*()/etc. version of UP
+ *                        builds. (which are NOPs on non-debug, non-preempt
+ *                        builds)
+ *
+ *   (included on UP-non-debug builds:)
+ *
+ *  linux/spinlock_api_up.h:
+ *                        builds the _spin_*() APIs.
+ *
+ *  linux/spinlock.h:     builds the final spin_*() APIs.

+ * Hardware-specific External Interface I/O core definitions
+ * for the BCM47xx family of SiliconBackplane-based chips.
+ *
+ * The External Interface core supports a total of three external chip selects
+ * supporting external interfaces. One of the external chip selects is
+ * used for Flash, one is used for PCMCIA, and the other may be
+ * programmed to support either a synchronous interface or an
+ * asynchronous interface. The asynchronous interface can be used to
+ * support external devices such as UARTs and the BCM2019 Bluetooth
+ * baseband processor.
+ * The external interface core also contains 2 on-chip 16550 UARTs, clock
+ * frequency control, a watchdog interrupt timer, and a GPIO interface.

+ *  RPC client per-operation statistics provide latency and retry

+ *  These statistics are not for detailed problem diagnosis, but simply
+ *  to indicate whether the problem is local or remote.

+ *  These counters are not meant to be human-readable, but are meant to be
+ *  integrated into system monitoring tools such as "sar" and "iostat".  As
+ *  such, the counters are sampled by the tools over time, and are never
+ *  zeroed after a file system is mounted.  Moving averages can be computed
+ *  by the tools by taking the difference between two instantaneous samples
+ *  and dividing that by the time between the samples.
+ *
+ *  The counters are maintained in a single array per RPC client, indexed
+ *  by procedure number.  There is no need to maintain separate counter
+ *  arrays per-CPU because these counters are always modified behind locks.

+ * of a universal address for use in allocating buffers and character
+ * arrays.
+ *
+ * Quoting RFC 3530, section 2.2:
+ *
+ * For TCP over IPv4 and for UDP over IPv4, the format of r_addr is the
+ * US-ASCII string:
+ *
+ *	h1.h2.h3.h4.p1.p2
+ *
+ * The prefix, "h1.h2.h3.h4", is the standard textual form for
+ * representing an IPv4 address, which is always four octets long.
+ * Assuming big-endian ordering, h1, h2, h3, and h4, are respectively,
+ * the first through fourth octets each converted to ASCII-decimal.
+ * Assuming big-endian ordering, p1 and p2 are, respectively, the first
+ * and second octets each converted to ASCII-decimal.  For example, if a
+ * host, in big-endian order, has an address of 0x0A010307 and there is
+ * a service listening on, in big endian order, port 0x020F (decimal
+ * 527), then the complete universal address is "10.1.3.7.2.15".
+ *
+ * ...
+ *
+ * For TCP over IPv6 and for UDP over IPv6, the format of r_addr is the
+ * US-ASCII string:
+ *
+ *	x1:x2:x3:x4:x5:x6:x7:x8.p1.p2
+ *
+ * The suffix "p1.p2" is the service port, and is computed the same way
+ * as with universal addresses for TCP and UDP over IPv4.  The prefix,
+ * "x1:x2:x3:x4:x5:x6:x7:x8", is the standard textual form for
+ * representing an IPv6 address as defined in Section 2.2 of [RFC2373].
+ * Additionally, the two alternative forms specified in Section 2.2 of

+/**
+ * struct platform_suspend_ops - Callbacks for managing platform dependent
+ *	system sleep states.
+ *
+ * @valid: Callback to determine if given system sleep state is supported by
+ *	the platform.
+ *	Valid (ie. supported) states are advertised in /sys/power/state.  Note
+ *	that it still may be impossible to enter given system sleep state if the
+ *	conditions aren't right.
+ *	There is the %suspend_valid_only_mem function available that can be
+ *	assigned to this if the platform only supports mem sleep.
+ *
+ * @begin: Initialise a transition to given system sleep state.
+ *	@begin() is executed right prior to suspending devices.  The information
+ *	conveyed to the platform code by @begin() should be disregarded by it as
+ *	soon as @end() is executed.  If @begin() fails (ie. returns nonzero),
+ *	@prepare(), @enter() and @finish() will not be called by the PM core.
+ *	This callback is optional.  However, if it is implemented, the argument
+ *	passed to @enter() is redundant and should be ignored.
+ *
+ * @prepare: Prepare the platform for entering the system sleep state indicated
+ *	by @begin().
+ *	@prepare() is called right after devices have been suspended (ie. the
+ *	appropriate .suspend() method has been executed for each device) and
+ *	before device drivers' late suspend callbacks are executed.  It returns
+ *	0 on success or a negative error code otherwise, in which case the
+ *	system cannot enter the desired sleep state (@prepare_late(), @enter(),
+ *	and @wake() will not be called in that case).
+ *
+ * @prepare_late: Finish preparing the platform for entering the system sleep
+ *	state indicated by @begin().
+ *	@prepare_late is called before disabling nonboot CPUs and after
+ *	device drivers' late suspend callbacks have been executed.  It returns
+ *	0 on success or a negative error code otherwise, in which case the
+ *	system cannot enter the desired sleep state (@enter() will not be
+ *	executed).
+ *
+ * @enter: Enter the system sleep state indicated by @begin() or represented by
+ *	the argument if @begin() is not implemented.
+ *	This callback is mandatory.  It returns 0 on success or a negative
+ *	error code otherwise, in which case the system cannot enter the desired
+ *	sleep state.
+ *
+ * @wake: Called when the system has just left a sleep state, right after
+ *	the nonboot CPUs have been enabled and before device drivers' early
+ *	resume callbacks are executed.
+ *	This callback is optional, but should be implemented by the platforms
+ *	that implement @prepare_late().  If implemented, it is always called
+ *	after @prepare_late and @enter(), even if one of them fails.
+ *
+ * @finish: Finish wake-up of the platform.
+ *	@finish is called right prior to calling device drivers' regular suspend
+ *	callbacks.
+ *	This callback is optional, but should be implemented by the platforms
+ *	that implement @prepare().  If implemented, it is always called after
+ *	@enter() and @wake(), even if any of them fails.  It is executed after
+ *	a failing @prepare.
+ *
+ * @suspend_again: Returns whether the system should suspend again (true) or
+ *	not (false). If the platform wants to poll sensors or execute some
+ *	code during suspended without invoking userspace and most of devices,
+ *	suspend_again callback is the place assuming that periodic-wakeup or
+ *	alarm-wakeup is already setup. This allows to execute some codes while
+ *	being kept suspended in the view of userland and devices.
+ *
+ * @end: Called by the PM core right after resuming devices, to indicate to
+ *	the platform that the system has returned to the working state or
+ *	the transition to the sleep state has been aborted.
+ *	This callback is optional, but should be implemented by the platforms
+ *	that implement @begin().  Accordingly, platforms implementing @begin()
+ *	should also provide a @end() which cleans up transitions aborted before
+ *	@enter().
+ *
+ * @recover: Recover the platform from a suspend failure.
+ *	Called by the PM core if the suspending of devices fails.
+ *	This callback is optional and should only be implemented by platforms
+ *	which require special recovery actions in that situation.

+ *	from waitq can be moved onto the txq.
+ *	Needs locking too.
+ * @lock: the lock to protect skbs, queues, and ST states.
+ * @protos_registered: count of the protocols registered, also when 0 the

+ *	needs to be downloaded to initialize chip side ST.
+ * @ll_state: the various PM states the chip can be, the states are notified
+ *	to us, when the chip sends relevant PM packets(SLEEP_IND, WAKE_IND).
+ * @kim_data: reference to the parent encapsulating structure.

+ * This file defines hook entry points called by core code where
+ * user tracing/debugging support might need to do something.  These
+ * entry points are called tracehook_*().  Each hook declared below
+ * has a detailed kerneldoc comment giving the context (locking et
+ * al) from which it is called, and the meaning of its return value.
+ *
+ * Each function here typically has only one call site, so it is ok
+ * to have some nontrivial tracehook_*() inlines.  In all cases, the
+ * fast path when no tracing is enabled should be very short.
+ *
+ * The purpose of this file and the tracehook_* layer is to consolidate
+ * the interface that the kernel core and arch code uses to enable any
+ * user debugging or tracing facility (such as ptrace).  The interfaces
+ * here are carefully documented so that maintainers of core and arch
+ * code do not need to think about the implementation details of the
+ * tracing facilities.  Likewise, maintainers of the tracing code do not
+ * need to understand all the calling core or arch code in detail, just
+ * documented circumstances of each call, such as locking conditions.
+ *
+ * If the calling core code changes so that locking is different, then
+ * it is ok to change the interface documented here.  The maintainer of
+ * core code changing should notify the maintainers of the tracing code
+ * that they need to work out the change.
+ *
+ * Some tracehook_*() inlines take arguments that the current tracing
+ * implementations might not necessarily use.  These function signatures
+ * are chosen to pass in all the information that is on hand in the
+ * caller and might conceivably be relevant to a tracer, so that the
+ * core code won't have to be updated when tracing adds more features.
+ * If a call site changes so that some of those parameters are no longer
+ * already on hand without extra work, then the tracehook_* interface
+ * can change so there is no make-work burden on the core code.  The
+ * maintainer of core code changing should notify the maintainers of the

+ *
+ *	Optional method. Default behaviour is to use the ttys array
+ *
+ * int (*install)(struct tty_driver *self, struct tty_struct *tty)
+ *
+ *	Install a new tty into the tty driver internal tables. Used in
+ *	conjunction with lookup and remove methods.
+ *
+ *	Optional method. Default behaviour is to use the ttys array
+ *
+ * void (*remove)(struct tty_driver *self, struct tty_struct *tty)
+ *
+ *	Remove a closed tty from the tty driver internal tables. Used in
+ *	conjunction with lookup and remove methods.
+ *
+ *	Optional method. Default behaviour is to use the ttys array
+ *
+ * int  (*open)(struct tty_struct * tty, struct file * filp);
+ *
+ * 	This routine is called when a particular tty device is opened.
+ * 	This routine is mandatory; if this routine is not filled in,
+ * 	the attempted open will fail with ENODEV.
+ *
+ *	Required method. Called with tty lock held.
+ *
+ * void (*close)(struct tty_struct * tty, struct file * filp);
+ *
+ * 	This routine is called when a particular tty device is closed.
+ *	Note: called even if the corresponding open() failed.
+ *
+ *	Required method. Called with tty lock held.
+ *
+ * void (*shutdown)(struct tty_struct * tty);
+ *
+ * 	This routine is called under the tty lock when a particular tty device
+ *	is closed for the last time. It executes before the tty resources
+ *	are freed so may execute while another function holds a tty kref.
+ *
+ * void (*cleanup)(struct tty_struct * tty);
+ *
+ *	This routine is called asynchronously when a particular tty device
+ *	is closed for the last time freeing up the resources. This is
+ *	actually the second part of shutdown for routines that might sleep.
+ *
+ *
+ * int (*write)(struct tty_struct * tty,
+ * 		 const unsigned char *buf, int count);
+ *
+ * 	This routine is called by the kernel to write a series of
+ * 	characters to the tty device.  The characters may come from
+ * 	user space or kernel space.  This routine will return the
+ *	number of characters actually accepted for writing.
+ *
+ *	Optional: Required for writable devices.
+ *
+ * int (*put_char)(struct tty_struct *tty, unsigned char ch);
+ *
+ * 	This routine is called by the kernel to write a single
+ * 	character to the tty device.  If the kernel uses this routine,
+ * 	it must call the flush_chars() routine (if defined) when it is
+ * 	done stuffing characters into the driver.  If there is no room
+ * 	in the queue, the character is ignored.
+ *
+ *	Optional: Kernel will use the write method if not provided.
+ *
+ *	Note: Do not call this function directly, call tty_put_char
+ *
+ * void (*flush_chars)(struct tty_struct *tty);
+ *
+ * 	This routine is called by the kernel after it has written a
+ * 	series of characters to the tty device using put_char().  
+ *
+ *	Optional:
+ *
+ *	Note: Do not call this function directly, call tty_driver_flush_chars
+ * 
+ * int  (*write_room)(struct tty_struct *tty);
+ *
+ * 	This routine returns the numbers of characters the tty driver
+ * 	will accept for queuing to be written.  This number is subject
+ * 	to change as output buffers get emptied, or if the output flow
+ *	control is acted.
+ *
+ *	Required if write method is provided else not needed.
+ *
+ *	Note: Do not call this function directly, call tty_write_room
+ * 
+ * int  (*ioctl)(struct tty_struct *tty, unsigned int cmd, unsigned long arg);
+ *
+ * 	This routine allows the tty driver to implement
+ *	device-specific ioctls.  If the ioctl number passed in cmd
+ * 	is not recognized by the driver, it should return ENOIOCTLCMD.
+ *
+ *	Optional
+ *
+ * long (*compat_ioctl)(struct tty_struct *tty,,
+ * 	                unsigned int cmd, unsigned long arg);
+ *
+ * 	implement ioctl processing for 32 bit process on 64 bit system
+ *
+ *	Optional
+ * 
+ * void (*set_termios)(struct tty_struct *tty, struct ktermios * old);
+ *
+ * 	This routine allows the tty driver to be notified when
+ * 	device's termios settings have changed.
+ *
+ *	Optional: Called under the termios lock
+ *
+ *
+ * void (*set_ldisc)(struct tty_struct *tty);
+ *
+ * 	This routine allows the tty driver to be notified when the
+ * 	device's termios settings have changed.
+ *
+ *	Optional: Called under BKL (currently)
+ * 
+ * void (*throttle)(struct tty_struct * tty);
+ *
+ * 	This routine notifies the tty driver that input buffers for
+ * 	the line discipline are close to full, and it should somehow
+ * 	signal that no more characters should be sent to the tty.
+ *
+ *	Optional: Always invoke via tty_throttle(), called under the
+ *	termios lock.
+ * 
+ * void (*unthrottle)(struct tty_struct * tty);
+ *
+ * 	This routine notifies the tty drivers that it should signals
+ * 	that characters can now be sent to the tty without fear of
+ * 	overrunning the input buffers of the line disciplines.
+ * 
+ *	Optional: Always invoke via tty_unthrottle(), called under the
+ *	termios lock.
+ *
+ * void (*stop)(struct tty_struct *tty);
+ *
+ * 	This routine notifies the tty driver that it should stop
+ * 	outputting characters to the tty device.  
+ *
+ *	Called with ->flow_lock held. Serialized with start() method.
+ *
+ *	Optional:
+ *
+ *	Note: Call stop_tty not this method.
+ * 
+ * void (*start)(struct tty_struct *tty);
+ *
+ * 	This routine notifies the tty driver that it resume sending
+ *	characters to the tty device.
+ *
+ *	Called with ->flow_lock held. Serialized with stop() method.
+ *
+ *	Optional:
+ *
+ *	Note: Call start_tty not this method.
+ * 
+ * void (*hangup)(struct tty_struct *tty);
+ *
+ * 	This routine notifies the tty driver that it should hang up the
+ * 	tty device.
+ *
+ *	Optional:
+ *
+ *	Called with tty lock held.
+ *
+ * int (*break_ctl)(struct tty_struct *tty, int state);
+ *
+ * 	This optional routine requests the tty driver to turn on or
+ * 	off BREAK status on the RS-232 port.  If state is -1,
+ * 	then the BREAK status should be turned on; if state is 0, then
+ * 	BREAK should be turned off.
+ *
+ * 	If this routine is implemented, the high-level tty driver will
+ * 	handle the following ioctls: TCSBRK, TCSBRKP, TIOCSBRK,
+ * 	TIOCCBRK.
+ *
+ *	If the driver sets TTY_DRIVER_HARDWARE_BREAK then the interface
+ *	will also be called with actual times and the hardware is expected
+ *	to do the delay work itself. 0 and -1 are still used for on/off.
+ *
+ *	Optional: Required for TCSBRK/BRKP/etc handling.
+ *
+ * void (*wait_until_sent)(struct tty_struct *tty, int timeout);
+ * 
+ * 	This routine waits until the device has written out all of the
+ * 	characters in its transmitter FIFO.
+ *
+ *	Optional: If not provided the device is assumed to have no FIFO
+ *
+ *	Note: Usually correct to call tty_wait_until_sent
+ *
+ * void (*send_xchar)(struct tty_struct *tty, char ch);
+ *
+ * 	This routine is used to send a high-priority XON/XOFF
+ * 	character to the device.
+ *
+ *	Optional: If not provided then the write method is called under
+ *	the atomic write lock to keep it serialized with the ldisc.
+ *
+ * int (*resize)(struct tty_struct *tty, struct winsize *ws)
+ *
+ *	Called when a termios request is issued which changes the
+ *	requested terminal geometry.
+ *
+ *	Optional: the default action is to update the termios structure
+ *	without error. This is usually the correct behaviour. Drivers should
+ *	not force errors here if they are not resizable objects (eg a serial
+ *	line). See tty_do_resize() if you need to wrap the standard method
+ *	in your own logic - the usual case.
+ *
+ * void (*set_termiox)(struct tty_struct *tty, struct termiox *new);
+ *
+ *	Called when the device receives a termiox based ioctl. Passes down
+ *	the requested data from user space. This method will not be invoked
+ *	unless the tty also has a valid tty->termiox pointer.
+ *
+ *	Optional: Called under the termios lock
+ *
+ * int (*get_icount)(struct tty_struct *tty, struct serial_icounter *icount);
+ *
+ *	Called when the device receives a TIOCGICOUNT ioctl. Passed a kernel
+ *	structure to complete. This method is optional and will only be called
+ *	if provided (otherwise EINVAL will be returned).

+ *	Called on a hangup. Tells the discipline that it should

+ * To properly implement 64bits network statistics on 32bit and 64bit hosts,
+ * we provide a synchronization point, that is a noop on 64bit or UP kernels.
+ *
+ * Key points :
+ * 1) Use a seqcount on SMP 32bits, with low overhead.
+ * 2) Whole thing is a noop on 64bit arches or UP kernels.
+ * 3) Write side must ensure mutual exclusion or one seqcount update could
+ *    be lost, thus blocking readers forever.
+ *    If this synchronization point is not a mutex, but a spinlock or
+ *    spinlock_bh() or disable_bh() :
+ * 3.1) Write side should not sleep.
+ * 3.2) Write side should not allow preemption.
+ * 3.3) If applicable, interrupts should be disabled.
+ *
+ * 4) If reader fetches several counters, there is no guarantee the whole values
+ *    are consistent (remember point 1) : this is a noop on 64bit arches anyway)
+ *
+ * 5) readers are allowed to sleep or be preempted/interrupted : They perform
+ *    pure reads. But if they have to fetch many values, it's better to not allow
+ *    preemptions/interruptions to avoid many retries.
+ *
+ * 6) If counter might be written by an interrupt, readers should block interrupts.
+ *    (On UP, there is no seqcount_t protection, a reader allowing interrupts could
+ *     read partial values)
+ *
+ * 7) For irq and softirq uses, readers can use u64_stats_fetch_begin_irq() and
+ *    u64_stats_fetch_retry_irq() helpers
+ *
+ * Usage :
+ *
+ * Stats producer (writer) should use following template granted it already got
+ * an exclusive access to counters (a lock is already taken, or per cpu
+ * data is used [in a non preemptable context])

+ *	If this interface does not use the USB major, this field should
+ *	be unused.  The driver should set this value in the probe()
+ *	function of the driver, after it has been assigned a minor
+ *	number from the USB core by calling usb_register_dev().
+ * @condition: binding state of the interface: not bound, binding
+ *	(in probe()), bound to a driver, or unbinding (in disconnect())

+ * @ep_devs_created: endpoint child pseudo-devices exist
+ * @unregistering: flag set when the interface is being unregistered

+ *	capability during autosuspend.
+ * @needs_altsetting0: flag set when a set-interface request for altsetting 0
+ *	has been deferred.
+ * @needs_binding: flag set when the driver should be re-probed or unbound
+ *	following a reset or suspend operation it doesn't support.
+ * @dev: driver model's view of this device
+ * @usb_dev: if an interface is bound to the USB major, this will point
+ *	to the sysfs representation for that device.
+ * @pm_usage_cnt: PM usage counter for this interface
+ * @reset_ws: Used for scheduling resets from atomic context.
+ * @resetting_device: USB core reset the device, so use alt setting 0 as
+ *	current; needs bandwidth alloc after reset.
+ *
+ * USB device drivers attach to interfaces on a physical device.  Each
+ * interface encapsulates a single high level function, such as feeding
+ * an audio stream to a speaker or reporting a change in a volume control.
+ * Many USB devices only have one interface.  The protocol used to talk to
+ * an interface's endpoints can be defined in a usb "class" specification,
+ * or by a product's vendor.  The (default) control endpoint is part of
+ * every interface, but is never listed among the interface's descriptors.
+ *
+ * The driver that is bound to the interface can use standard driver model
+ * calls such as dev_get_drvdata() on the dev member of this structure.
+ *
+ * Each interface may have alternate settings.  The initial configuration
+ * of a device sets altsetting 0, but the device driver can change
+ * that setting using usb_set_interface().  Alternate settings are often
+ * used to control the use of periodic endpoints, such as by having
+ * different endpoints use different amounts of reserved USB bandwidth.
+ * All standards-conformant USB devices that use isochronous endpoints
+ * will use them in non-default settings.
+ *
+ * The USB specification says that alternate setting numbers must run from
+ * 0 to one less than the total number of alternate settings.  But some
+ * devices manage to mess this up, and the structures aren't necessarily
+ * stored in numerical order anyhow.  Use usb_altnum_to_altsetting() to
+ * look up an alternate setting in the altsetting array based on its number.

+ * reconfigured, by re-cabling a tree of USB devices or by moving USB host
+ * controllers.  Adding and removing devices, including virtual root hubs
+ * in host controller driver modules, does not change these path identifiers;
+ * neither does rebooting or re-enumerating.  These are more useful identifiers
+ * than changeable ("unstable") ones like bus numbers or device addresses.
+ *
+ * With a partial exception for devices connected to USB 2.0 root hubs, these
+ * identifiers are also predictable.  So long as the device tree isn't changed,
+ * plugging any USB device into a given hub port always gives it the same path.
+ * Because of the use of "companion" controllers, devices connected to ports on
+ * USB 2.0 root hubs (EHCI host controllers) will get one path ID if they are
+ * high speed, and a different one if they are full or low speed.

+ * @anchor_list: membership in the list of an anchor
+ * @anchor: to anchor URBs to a common mooring
+ * @ep: Points to the endpoint's data structure.  Will eventually
+ *	replace @pipe.
+ * @pipe: Holds endpoint number, direction, type, and more.
+ *	Create these values with the eight macros available;
+ *	usb_{snd,rcv}TYPEpipe(dev,endpoint), where the TYPE is "ctrl"
+ *	(control), "bulk", "int" (interrupt), or "iso" (isochronous).
+ *	For example usb_sndbulkpipe() or usb_rcvintpipe().  Endpoint
+ *	numbers range from zero to fifteen.  Note that "in" endpoint two
+ *	is a different endpoint (and pipe) from "out" endpoint two.
+ *	The current configuration controls the existence, type, and
+ *	maximum packet size of any given endpoint.
+ * @stream_id: the endpoint's stream ID for bulk streams
+ * @dev: Identifies the USB device to perform the request.
+ * @status: This is read in non-iso completion functions to get the
+ *	status of the particular request.  ISO requests only use it
+ *	to tell whether the URB was unlinked; detailed status for
+ *	each frame is in the fields of the iso_frame-desc.
+ * @transfer_flags: A variety of flags may be used to affect how URB
+ *	submission, unlinking, or operation are handled.  Different
+ *	kinds of URB can use different flags.
+ * @transfer_buffer:  This identifies the buffer to (or from) which the I/O
+ *	request will be performed unless URB_NO_TRANSFER_DMA_MAP is set
+ *	(however, do not leave garbage in transfer_buffer even then).
+ *	This buffer must be suitable for DMA; allocate it with
+ *	kmalloc() or equivalent.  For transfers to "in" endpoints, contents
+ *	of this buffer will be modified.  This buffer is used for the data
+ *	stage of control transfers.
+ * @transfer_dma: When transfer_flags includes URB_NO_TRANSFER_DMA_MAP,
+ *	the device driver is saying that it provided this DMA address,
+ *	which the host controller driver should use in preference to the
+ *	transfer_buffer.
+ * @sg: scatter gather buffer list, the buffer size of each element in
+ * 	the list (except the last) must be divisible by the endpoint's
+ * 	max packet size if no_sg_constraint isn't set in 'struct usb_bus'
+ * @num_mapped_sgs: (internal) number of mapped sg entries
+ * @num_sgs: number of entries in the sg list
+ * @transfer_buffer_length: How big is transfer_buffer.  The transfer may
+ *	be broken up into chunks according to the current maximum packet
+ *	size for the endpoint, which is a function of the configuration
+ *	and is encoded in the pipe.  When the length is zero, neither
+ *	transfer_buffer nor transfer_dma is used.
+ * @actual_length: This is read in non-iso completion functions, and
+ *	it tells how many bytes (out of transfer_buffer_length) were
+ *	transferred.  It will normally be the same as requested, unless
+ *	either an error was reported or a short read was performed.
+ *	The URB_SHORT_NOT_OK transfer flag may be used to make such
+ *	short reads be reported as errors.
+ * @setup_packet: Only used for control transfers, this points to eight bytes
+ *	of setup data.  Control transfers always start by sending this data
+ *	to the device.  Then transfer_buffer is read or written, if needed.
+ * @setup_dma: DMA pointer for the setup packet.  The caller must not use
+ *	this field; setup_packet must point to a valid buffer.
+ * @start_frame: Returns the initial frame for isochronous transfers.
+ * @number_of_packets: Lists the number of ISO transfer buffers.
+ * @interval: Specifies the polling interval for interrupt or isochronous
+ *	transfers.  The units are frames (milliseconds) for full and low
+ *	speed devices, and microframes (1/8 millisecond) for highspeed
+ *	and SuperSpeed devices.
+ * @error_count: Returns the number of ISO transfers that reported errors.
+ * @context: For use in completion functions.  This normally points to
+ *	request-specific driver context.
+ * @complete: Completion handler. This URB is passed as the parameter to the
+ *	completion function.  The completion function may then do what
+ *	it likes with the URB, including resubmitting or freeing it.
+ * @iso_frame_desc: Used to provide arrays of ISO transfer buffers and to
+ *	collect the transfer status for each buffer.
+ *
+ * This structure identifies USB transfer requests.  URBs must be allocated by
+ * calling usb_alloc_urb() and freed with a call to usb_free_urb().
+ * Initialization may be done using various usb_fill_*_urb() functions.  URBs
+ * are submitted using usb_submit_urb(), and pending requests may be canceled
+ * using usb_unlink_urb() or usb_kill_urb().
+ *
+ * Data Transfer Buffers:
+ *
+ * Normally drivers provide I/O buffers allocated with kmalloc() or otherwise
+ * taken from the general page pool.  That is provided by transfer_buffer
+ * (control requests also use setup_packet), and host controller drivers
+ * perform a dma mapping (and unmapping) for each buffer transferred.  Those
+ * mapping operations can be expensive on some platforms (perhaps using a dma
+ * bounce buffer or talking to an IOMMU),
+ * although they're cheap on commodity x86 and ppc hardware.
+ *
+ * Alternatively, drivers may pass the URB_NO_TRANSFER_DMA_MAP transfer flag,
+ * which tells the host controller driver that no such mapping is needed for
+ * the transfer_buffer since
+ * the device driver is DMA-aware.  For example, a device driver might
+ * allocate a DMA buffer with usb_alloc_coherent() or call usb_buffer_map().
+ * When this transfer flag is provided, host controller drivers will
+ * attempt to use the dma address found in the transfer_dma
+ * field rather than determining a dma address themselves.
+ *
+ * Note that transfer_buffer must still be set if the controller
+ * does not support DMA (as indicated by bus.uses_dma) and when talking
+ * to root hub. If you have to trasfer between highmem zone and the device
+ * on such controller, create a bounce buffer or bail out with an error.
+ * If transfer_buffer cannot be set (is in highmem) and the controller is DMA
+ * capable, assign NULL to it, so that usbmon knows not to use the value.
+ * The setup_packet must always be set, so it cannot be located in highmem.
+ *

+ * All URBs submitted must initialize the dev, pipe, transfer_flags (may be
+ * zero), and complete fields.  All URBs must also initialize
+ * transfer_buffer and transfer_buffer_length.  They may provide the
+ * URB_SHORT_NOT_OK transfer flag, indicating that short reads are
+ * to be treated as errors; that flag is invalid for write requests.
+ *
+ * Bulk URBs may
+ * use the URB_ZERO_PACKET transfer flag, indicating that bulk OUT transfers
+ * should always terminate with a short packet, even if it means adding an
+ * extra zero length packet.
+ *
+ * Control URBs must provide a valid pointer in the setup_packet field.
+ * Unlike the transfer_buffer, the setup_packet may not be mapped for DMA
+ * beforehand.
+ *
+ * Interrupt URBs must provide an interval, saying how often (in milliseconds
+ * or, for highspeed devices, 125 microsecond units)
+ * to poll for transfers.  After the URB has been submitted, the interval
+ * field reflects how the transfer was actually scheduled.
+ * The polling interval may be more frequent than requested.
+ * For example, some controllers have a maximum interval of 32 milliseconds,
+ * while others support intervals of up to 1024 milliseconds.
+ * Isochronous URBs also have transfer intervals.  (Note that for isochronous
+ * endpoints, as well as high speed interrupt endpoints, the encoding of
+ * the transfer interval in the endpoint descriptor is logarithmic.
+ * Device drivers must convert that value to linear units themselves.)
+ *
+ * If an isochronous endpoint queue isn't already running, the host
+ * controller will schedule a new URB to start as soon as bandwidth
+ * utilization allows.  If the queue is running then a new URB will be
+ * scheduled to start in the first transfer slot following the end of the
+ * preceding URB, if that slot has not already expired.  If the slot has
+ * expired (which can happen when IRQ delivery is delayed for a long time),
+ * the scheduling behavior depends on the URB_ISO_ASAP flag.  If the flag
+ * is clear then the URB will be scheduled to start in the expired slot,
+ * implying that some of its packets will not be transferred; if the flag
+ * is set then the URB will be scheduled in the first unexpired slot,
+ * breaking the queue's synchronization.  Upon URB completion, the
+ * start_frame field will be set to the (micro)frame number in which the
+ * transfer was scheduled.  Ranges for frame counter values are HC-specific
+ * and can go from as low as 256 to as high as 65536 frames.
+ *
+ * Isochronous URBs have a different data transfer model, in part because
+ * the quality of service is only "best effort".  Callers provide specially
+ * allocated URBs, with number_of_packets worth of iso_frame_desc structures
+ * at the end.  Each such packet is an individual ISO transfer.  Isochronous
+ * URBs are normally queued, submitted by drivers to arrange that
+ * transfers are at least double buffered, and then explicitly resubmitted
+ * in completion handlers, so
+ * that data (such as audio or video) streams at as constant a rate as the
+ * host controller scheduler can support.
+ *
+ * Completion Callbacks:
+ *
+ * The completion callback is made in_interrupt(), and one of the first
+ * things that a completion handler should do is check the status field.
+ * The status field is provided for all URBs.  It is used to report
+ * unlinked URBs, and status for all non-ISO transfers.  It should not
+ * be examined before the URB is returned to the completion handler.
+ *
+ * The context field is normally used to link URBs back to the relevant
+ * driver or request state.
+ *
+ * When the completion callback is invoked for non-isochronous URBs, the
+ * actual_length field tells how many bytes were transferred.  This field
+ * is updated even when the URB terminated with an error or was unlinked.
+ *
+ * ISO transfer status is reported in the status and actual_length fields
+ * of the iso_frame_desc array, and the number of errors is reported in
+ * error_count.  Completion callbacks for ISO transfers will normally
+ * (re)submit URBs to ensure a constant transfer rate.
+ *
+ * Note that even fields marked "public" should not be touched by the driver
+ * when the urb is owned by the hcd, that is, since the call to
+ * usb_submit_urb() till the entry into the completion routine.

+ * There's also "Wireless USB", using low power short range radios for

+ * @free_func: free the struct usb_function.
+ * @mod: (internal) points to the module that created this structure.
+ * @set_alt: (REQUIRED) Reconfigures altsettings; function drivers may
+ *	initialize usb_ep.driver data at this time (when it is used).
+ *	Note that setting an interface to its current altsetting resets
+ *	interface state, and that all interfaces have a disabled state.
+ * @get_alt: Returns the active altsetting.  If this is not provided,
+ *	then only altsetting zero is supported.
+ * @disable: (REQUIRED) Indicates the function should be disabled.  Reasons
+ *	include host resetting or reconfiguring the gadget, and disconnection.
+ * @setup: Used for interface-specific control requests.
+ * @req_match: Tests if a given class request can be handled by this function.
+ * @suspend: Notifies functions when the host stops sending USB traffic.
+ * @resume: Notifies functions when the host restarts USB traffic.
+ * @get_status: Returns function status as a reply to
+ *	GetStatus() request when the recipient is Interface.
+ * @func_suspend: callback to be called when
+ *	SetFeature(FUNCTION_SUSPEND) is reseived
+ *
+ * A single USB function uses one or more interfaces, and should in most
+ * cases support operation at both full and high speeds.  Each function is
+ * associated by @usb_add_function() with a one configuration; that function
+ * causes @bind() to be called so resources can be allocated as part of
+ * setting up a gadget driver.  Those resources include endpoints, which
+ * should be allocated using @usb_ep_autoconfig().
+ *
+ * To support dual speed operation, a function driver provides descriptors
+ * for both high and full speed operation.  Except in rare cases that don't
+ * involve bulk endpoints, each speed needs different endpoint descriptors.
+ *
+ * Function drivers choose their own strategies for managing instance data.
+ * The simplest strategy just declares it "static', which means the function
+ * can only be activated once.  If the function needs to be exposed in more
+ * than one configuration at a given speed, it needs to support multiple
+ * usb_function structures (one for each configuration).
+ *
+ * A more complex strategy might encapsulate a @usb_function structure inside
+ * a driver-specific instance structure to allows multiple activations.  An
+ * example of multiple activations might be a CDC ACM function that supports
+ * two or more distinct instances within the same configuration, providing
+ * several independent logical data links to a USB host.

+ * struct usb_request - describes one i/o request

+ * @dma: DMA address corresponding to 'buf'.  If you don't set this
+ *	field, and the usb controller needs one, it is responsible
+ *	for mapping and unmapping the buffer.
+ * @sg: a scatterlist for SG-capable controllers.
+ * @num_sgs: number of SG entries
+ * @num_mapped_sgs: number of SG entries mapped to DMA (internal)
+ * @length: Length of that data
+ * @stream_id: The stream id, when USB3.0 bulk streams are being used
+ * @no_interrupt: If true, hints that no completion irq is needed.
+ *	Helpful sometimes with deep request queues that are handled
+ *	directly by DMA controllers.
+ * @zero: If true, when writing data, makes the last packet be "short"
+ *     by adding a zero length packet as needed;
+ * @short_not_ok: When reading data, makes short packets be
+ *     treated as errors (queue stops advancing till cleanup).
+ * @complete: Function called when request completes, so this request and
+ *	its buffer may be re-used.  The function will always be called with
+ *	interrupts disabled, and it must not sleep.
+ *	Reads terminate with a short packet, or when the buffer fills,
+ *	whichever comes first.  When writes terminate, some data bytes
+ *	will usually still be in flight (often in a hardware fifo).
+ *	Errors (for reads or writes) stop the queue from advancing
+ *	until the completion function returns, so that any transfers
+ *	invalidated by the error may first be dequeued.
+ * @context: For use by the completion callback
+ * @list: For use by the gadget driver.
+ * @status: Reports completion code, zero or a negative errno.
+ *	Normally, faults block the transfer queue from advancing until
+ *	the completion callback returns.
+ *	Code "-ESHUTDOWN" indicates completion caused by device disconnect,
+ *	or when the driver disabled the endpoint.
+ * @actual: Reports bytes transferred to/from the buffer.  For reads (OUT
+ *	transfers) this may be less than the requested length.  If the
+ *	short_not_ok flag is set, short reads are treated as errors
+ *	even when status otherwise indicates successful completion.
+ *	Note that for writes (IN transfers) some data bytes may still
+ *	reside in a device-side FIFO when the request is reported as
+ *	complete.
+ *
+ * These are allocated/freed through the endpoint they're used with.  The
+ * hardware's driver can add extra per-request data to the memory it returns,
+ * which often avoids separate memory allocations (potential failures),
+ * later when the request is queued.
+ *
+ * Request flags affect request handling, such as whether a zero length
+ * packet is written (the "zero" flag), whether a short read should be
+ * treated as an error (blocking request queue advance, the "short_not_ok"
+ * flag), or hinting that an interrupt is not required (the "no_interrupt"
+ * flag, for use with deep request queues).
+ *
+ * Bulk endpoints can use any size buffers, and can also be used for interrupt
+ * transfers. interrupt-only endpoints can be much less functional.
+ *
+ * NOTE:  this is analogous to 'struct urb' on the host side, except that
+ * it's thinner and promotes more pre-allocation.

+ * This tells the device controller to perform the specified request through

+ * request queued; they complete in FIFO order.  Once a gadget driver
+ * submits a request, that request may not be examined or modified until it
+ * is given back to that driver through the completion callback.
+ *
+ * Each request is turned into one or more packets.  The controller driver
+ * never merges adjacent requests into the same packet.  OUT transfers
+ * will sometimes use data that's already buffered in the hardware.
+ * Drivers can rely on the fact that the first byte of the request's buffer
+ * always corresponds to the first byte of some USB packet, for both

+ *
+ * Bulk endpoints can queue any amount of data; the transfer is packetized
+ * automatically.  The last packet will be short if the request doesn't fill it

+ * protocols since not all usb hardware can successfully handle zero length
+ * packets.  (ZLPs may be explicitly written, and may be implicitly written if
+ * the request 'zero' flag is set.)  Bulk endpoints may also be used
+ * for interrupt transfers; but the reverse is not true, and some endpoints
+ * won't support every interrupt transfer.  (Such as 768 byte packets.)
+ *
+ * Interrupt-only endpoints are less functional than bulk endpoints, for
+ * example by not supporting queueing or not handling buffers that are
+ * larger than the endpoint's maxpacket size.  They may also treat data
+ * toggle differently.
+ *
+ * Control endpoints ... after getting a setup() callback, the driver queues
+ * one response (even if it would be zero length).  That enables the
+ * status ack, after transferring data as specified in the response.  Setup
+ * functions may return negative error codes to generate protocol stalls.
+ * (Note that some USB device controllers disallow protocol stall responses
+ * in some cases.)  When control responses are deferred (the response is
+ * written after the setup callback returns), then usb_ep_set_halt() may be
+ * used on ep0 to trigger protocol stalls.  Depending on the controller,
+ * it may not be possible to trigger a status-stage protocol stall when the
+ * data stage is over, that is, from within the response's completion
+ * routine.
+ *
+ * For periodic endpoints, like interrupt or isochronous ones, the usb host

+ * @probe: pointer to the driver's probe function.
+ *	This will be called when the device is inserted into the system,
+ *	but before the device has been fully initialized by the usb_serial
+ *	subsystem.  Use this function to download any firmware to the device,
+ *	or any other early initialization that might be needed.

+ *	set up.  Do any local initialization of the device, or any private
+ *	memory structure allocation at this point in time.
+ * @disconnect: pointer to the driver's disconnect function.  This will be

+ * @release: pointer to the driver's release function.  This will be called
+ *	when the usb_serial data structure is about to be destroyed.
+ * @usb_driver: pointer to the struct usb_driver that controls this

+ * The driver.name field should be set to the name of this driver (remember

+ * events/notifications will have a size impossible to determine
+ * unless we know about the device's specific details.
+ *
+ * It was way too smart of the spec writers not to think that it would

+ * events/notifications if there are no LENGTH fields in the HEADER of
+ * each message...the transaction size cannot be counted on as the
+ * spec does not forbid to pack more than one event in a single
+ * transaction.
+ *
+ * Thus, we guess sizes with tables (or for events, when you know the
+ * size ahead of time you can use uwb_rc_neh_extra_size*()). We
+ * register tables with the known events and their sizes, and then we
+ * traverse those tables. For those with variable length, we provide a
+ * way to lookup the size inside the event/notification's
+ * payload. This allows device-specific event size tables to be
+ * registered.
+ *
+ * @size:   Size of the payload
+ *
+ * @offset: if != 0, at offset @offset-1 starts a field with a length
+ *          that has to be added to @size. The format of the field is
+ *          given by @type.
+ *
+ * @type:   Type and length of the offset field. Most common is LE 16

+ *
+ * This file is released under the GPLv2
+ *
+ * UMC (UWB Multi-interface Controller) capabilities (e.g., radio
+ * controller, host controller) are presented as devices on the "umc"
+ * bus.
+ *
+ * The radio controller is not strictly a UMC capability but it's
+ * useful to present it as such.
+ *
+ * References:
+ *
+ *   [WHCI] Wireless Host Controller Interface Specification for
+ *          Certified Wireless Universal Serial Bus, revision 0.95.
+ *
+ * How this works is kind of convoluted but simple. The whci.ko driver
+ * loads when WHCI devices are detected. These WHCI devices expose
+ * many devices in the same PCI function (they couldn't have reused
+ * functions, no), so for each PCI function that exposes these many
+ * devices, whci ceates a umc_dev [whci_probe() -> whci_add_cap()]
+ * with umc_device_create() and adds it to the bus with
+ * umc_device_register().
+ *
+ * umc_device_register() calls device_register() which will push the
+ * bus management code to load your UMC driver's somehting_probe()
+ * that you have registered for that capability code.
+ *
+ * Now when the WHCI device is removed, whci_remove() will go over
+ * each umc_dev assigned to each of the PCI function's capabilities
+ * and through whci_del_cap() call umc_device_unregister() each
+ * created umc_dev. Of course, if you are bound to the device, your
+ * driver's something_remove() will be called.

+ * struct vmci_queue_header - VMCI Queue Header information.
+ *
+ * A Queue cannot stand by itself as designed.  Each Queue's header
+ * contains a pointer into itself (the producer_tail) and into its peer
+ * (consumer_head).  The reason for the separation is one of
+ * accessibility: Each end-point can modify two things: where the next
+ * location to enqueue is within its produce_q (producer_tail); and
+ * where the next dequeue location is in its consume_q (consumer_head).
+ *
+ * An end-point cannot modify the pointers of its peer (guest to
+ * guest; NOTE that in the host both queue headers are mapped r/w).
+ * But, each end-point needs read access to both Queue header
+ * structures in order to determine how much space is used (or left)
+ * in the Queue.  This is because for an end-point to know how full
+ * its produce_q is, it needs to use the consumer_head that points into
+ * the produce_q but -that- consumer_head is in the Queue header for
+ * that end-points consume_q.
+ *
+ * Thoroughly confused?  Sorry.
+ *
+ * producer_tail: the point to enqueue new entrants.  When you approach
+ * a line in a store, for example, you walk up to the tail.
+ *
+ * consumer_head: the point in the queue from which the next element is
+ * dequeued.  In other words, who is next in line is he who is at the
+ * head of the line.
+ *
+ * Also, producer_tail points to an empty byte in the Queue, whereas
+ * consumer_head points to a valid byte of data (unless producer_tail ==
+ * consumer_head in which case consumer_head does not point to a valid
+ * byte of data).
+ *
+ * For a queue of buffer 'size' bytes, the tail and head pointers will be in
+ * the range [0, size-1].
+ *
+ * If produce_q_header->producer_tail == consume_q_header->consumer_head
+ * then the produce_q is empty.

+ *
+ *
+ * EXECUTING DEBUGGING ACTIONS OR NOT
+ *
+ * The main thing this framework provides is decission power to take a
+ * debug action (like printing a message) if the current debug level
+ * allows it.
+ *
+ * The decission power is at two levels: at compile-time (what does
+ * not make it is compiled out) and at run-time. The run-time
+ * selection is done per-submodule (as they are declared by the user
+ * of the framework).
+ *
+ * A call to d_test(L) (L being the target debug level) returns true
+ * if the action should be taken because the current debug levels
+ * allow it (both compile and run time).
+ *
+ * It follows that a call to d_test() that can be determined to be
+ * always false at compile time will get the code depending on it
+ * compiled out by optimization.
+ *
+ *
+ * DEBUG LEVELS
+ *
+ * It is up to the caller to define how much a debugging level is.
+ *
+ * Convention sets 0 as "no debug" (so an action marked as debug level 0
+ * will always be taken). The increasing debug levels are used for
+ * increased verbosity.
+ *
+ *
+ * USAGE
+ *
+ * Group the code in modules and submodules inside each module [which
+ * in most cases maps to Linux modules and .c files that compose
+ * those].
+ *
+ *
+ * For each module, there is:
+ *
+ *  - a MODULENAME (single word, legal C identifier)
+ *
+ *  - a debug-levels.h header file that declares the list of
+ *    submodules and that is included by all .c files that use
+ *    the debugging tools. The file name can be anything.
+ *
+ *  - some (optional) .c code to manipulate the runtime debug levels
+ *    through debugfs.
+ *
+ * The debug-levels.h file would look like:
+ *
+ *     #ifndef __debug_levels__h__
+ *     #define __debug_levels__h__
+ *
+ *     #define D_MODULENAME modulename
+ *     #define D_MASTER 10
+ *
+ *     #include <linux/wimax/debug.h>
+ *
+ *     enum d_module {
+ *             D_SUBMODULE_DECLARE(submodule_1),
+ *             D_SUBMODULE_DECLARE(submodule_2),
+ *             ...
+ *             D_SUBMODULE_DECLARE(submodule_N)
+ *     };
+ *
+ *     #endif
+ *
+ * D_MASTER is the maximum compile-time debug level; any debug actions
+ * above this will be out. D_MODULENAME is the module name (legal C
+ * identifier), which has to be unique for each module (to avoid
+ * namespace collisions during linkage). Note those #defines need to
+ * be done before #including debug.h
+ *
+ * We declare N different submodules whose debug level can be
+ * independently controlled during runtime.
+ *
+ * In a .c file of the module (and only in one of them), define the
+ * following code:
+ *
+ *     struct d_level D_LEVEL[] = {
+ *             D_SUBMODULE_DEFINE(submodule_1),
+ *             D_SUBMODULE_DEFINE(submodule_2),
+ *             ...
+ *             D_SUBMODULE_DEFINE(submodule_N),
+ *     };
+ *     size_t D_LEVEL_SIZE = ARRAY_SIZE(D_LEVEL);
+ *
+ * Externs for d_level_MODULENAME and d_level_size_MODULENAME are used
+ * and declared in this file using the D_LEVEL and D_LEVEL_SIZE macros
+ * #defined also in this file.
+ *
+ * To manipulate from user space the levels, create a debugfs dentry
+ * and then register each submodule with:
+ *
+ *     result = d_level_register_debugfs("PREFIX_", submodule_X, parent);
+ *     if (result < 0)
+ *            goto error;
+ *
+ * Where PREFIX_ is a name of your chosing. This will create debugfs
+ * file with a single numeric value that can be use to tweak it. To
+ * remove the entires, just use debugfs_remove_recursive() on 'parent'.
+ *
+ * NOTE: remember that even if this will show attached to some
+ *     particular instance of a device, the settings are *global*.
+ *
+ *
+ * On each submodule (for example, .c files), the debug infrastructure
+ * should be included like this:
+ *
+ *     #define D_SUBMODULE submodule_x     // matches one in debug-levels.h
+ *     #include "debug-levels.h"
+ *
+ * after #including all your include files.
+ *
+ *
+ * Now you can use the d_*() macros below [d_test(), d_fnstart(),
+ * d_fnend(), d_printf(), d_dump()].
+ *
+ * If their debug level is greater than D_MASTER, they will be
+ * compiled out.
+ *
+ * If their debug level is lower or equal than D_MASTER but greater
+ * than the current debug level of their submodule, they'll be
+ * ignored.
+ *
+ * Otherwise, the action will be performed.

+     The 'zlib' compression library provides in-memory compression and
+  decompression functions, including integrity checks of the uncompressed
+  data.  This version of the library supports only one compression method
+  (deflation) but other algorithms will be added later and will have the same
+  stream interface.
+
+     Compression can be done in a single step if the buffers are large
+  enough (for example if an input file is mmap'ed), or can be done by
+  repeated calls of the compression function.  In the latter case, the
+  application must provide more input and/or consume the output
+  (providing more output space) before each call.
+
+     The compressed data format used by default by the in-memory functions is
+  the zlib format, which is a zlib wrapper documented in RFC 1950, wrapped
+  around a deflate stream, which is itself documented in RFC 1951.
+
+     The library also supports reading and writing files in gzip (.gz) format
+  with an interface similar to that of stdio.
+
+     The zlib format was designed to be compact and fast for use in memory
+  and on communications channels.  The gzip format was designed for single-
+  file compression on file systems, has a larger header than zlib to maintain
+  directory information, and uses a different, slower check method than zlib.
+
+     The library does not install any signal handler. The decoder checks
+  the consistency of the compressed data, so the library should never
+  crash even in case of corrupted input.

+    deflate compresses as much data as possible, and stops when the input
+  buffer becomes empty or the output buffer becomes full. It may introduce some
+  output latency (reading input without producing any output) except when
+  forced to flush.
+
+    The detailed semantics are as follows. deflate performs one or both of the
+  following actions:
+
+  - Compress more input starting at next_in and update next_in and avail_in
+    accordingly. If not all input can be processed (because there is not
+    enough room in the output buffer), next_in and avail_in are updated and
+    processing will resume at this point for the next call of deflate().
+
+  - Provide more output starting at next_out and update next_out and avail_out
+    accordingly. This action is forced if the parameter flush is non zero.
+    Forcing flush frequently degrades the compression ratio, so this parameter
+    should be set only when necessary (in interactive applications).
+    Some output may be provided even if flush is not set.
+
+  Before the call of deflate(), the application should ensure that at least
+  one of the actions is possible, by providing more input and/or consuming
+  more output, and updating avail_in or avail_out accordingly; avail_out
+  should never be zero before the call. The application can consume the
+  compressed output when it wants, for example when the output buffer is full
+  (avail_out == 0), or after each call of deflate(). If deflate returns Z_OK
+  and with zero avail_out, it must be called again after making room in the
+  output buffer because there might be more output pending.
+
+    If the parameter flush is set to Z_SYNC_FLUSH, all pending output is
+  flushed to the output buffer and the output is aligned on a byte boundary, so
+  that the decompressor can get all input data available so far. (In particular
+  avail_in is zero after the call if enough output space has been provided
+  before the call.)  Flushing may degrade compression for some compression
+  algorithms and so it should be used only when necessary.
+
+    If flush is set to Z_FULL_FLUSH, all output is flushed as with
+  Z_SYNC_FLUSH, and the compression state is reset so that decompression can
+  restart from this point if previous compressed data has been damaged or if
+  random access is desired. Using Z_FULL_FLUSH too often can seriously degrade
+  the compression.
+
+    If deflate returns with avail_out == 0, this function must be called again
+  with the same value of the flush parameter and more output space (updated
+  avail_out), until the flush is complete (deflate returns with non-zero
+  avail_out).
+
+    If the parameter flush is set to Z_FINISH, pending input is processed,
+  pending output is flushed and deflate returns with Z_STREAM_END if there
+  was enough output space; if deflate returns with Z_OK, this function must be
+  called again with Z_FINISH and more output space (updated avail_out) but no
+  more input data, until it returns with Z_STREAM_END or an error. After
+  deflate has returned Z_STREAM_END, the only possible operations on the
+  stream are deflateReset or deflateEnd.
+  
+    Z_FINISH can be used immediately after deflateInit if all the compression
+  is to be done in a single step. In this case, avail_out must be at least
+  0.1% larger than avail_in plus 12 bytes.  If deflate does not return
+  Z_STREAM_END, then it must be called again as described above.
+
+    deflate() sets strm->adler to the adler32 checksum of all input read
+  so far (that is, total_in bytes).
+
+    deflate() may update data_type if it can make a good guess about
+  the input data type (Z_ASCII or Z_BINARY). In doubt, the data is considered
+  binary. This field is only for information purposes and does not affect
+  the compression algorithm in any manner.
+
+    deflate() returns Z_OK if some progress has been made (more input
+  processed or more output produced), Z_STREAM_END if all input has been
+  consumed and all output has been produced (only when flush is set to
+  Z_FINISH), Z_STREAM_ERROR if the stream state was inconsistent (for example

+  Z_FINISH, or Z_BLOCK. Z_SYNC_FLUSH requests that inflate() flush as much
+  output as possible to the output buffer. Z_BLOCK requests that inflate() stop
+  if and when it gets to the next deflate block boundary. When decoding the
+  zlib or gzip format, this will cause inflate() to return immediately after
+  the header and before the first block. When doing a raw inflate, inflate()
+  will go ahead and process the first block, and will return when it gets to
+  the end of that block, or when it runs out of data.
+
+    The Z_BLOCK option assists in appending to or combining deflate streams.
+  Also to assist in this, on return inflate() will set strm->data_type to the
+  number of unused bits in the last byte taken from strm->next_in, plus 64
+  if inflate() is currently decoding the last block in the deflate stream,
+  plus 128 if inflate() returned immediately after decoding an end-of-block
+  code or decoding the complete header up to just before the first byte of the
+  deflate stream. The end-of-block will not be indicated until all of the
+  uncompressed data from that block has been written to strm->next_out.  The
+  number of unused bits may in general be greater than seven, except when
+  bit 7 of data_type is set, in which case the number of unused bits will be
+  less than eight.
+
+    inflate() should normally be called until it returns Z_STREAM_END or an
+  error. However if all decompression is to be performed in a single step
+  (a single call of inflate), the parameter flush should be set to
+  Z_FINISH. In this case all pending input is processed and all pending
+  output is flushed; avail_out must be large enough to hold all the
+  uncompressed data. (The size of the uncompressed data may have been saved
+  by the compressor for this purpose.) The next operation on this stream must
+  be inflateEnd to deallocate the decompression state. The use of Z_FINISH
+  is never required, but can be used to inform inflate that a faster approach
+  may be used for the single inflate() call.
+
+     In this implementation, inflate() always flushes as much output as
+  possible to the output buffer, and always uses the faster approach on the
+  first call. So the only effect of the flush parameter in this implementation
+  is on the return value of inflate(), as noted below, or when it returns early
+  because Z_BLOCK is used.
+
+     If a preset dictionary is needed after this call (see inflateSetDictionary
+  below), inflate sets strm->adler to the adler32 checksum of the dictionary
+  chosen by the compressor and returns Z_NEED_DICT; otherwise it sets
+  strm->adler to the adler32 checksum of all output produced so far (that is,
+  total_out bytes) and returns Z_OK, Z_STREAM_END or an error code as described
+  below. At the end of the stream, inflate() checks that its computed adler32
+  checksum is equal to that saved by the compressor and returns Z_STREAM_END
+  only if the checksum is correct.
+
+    inflate() will decompress and check either zlib-wrapped or gzip-wrapped
+  deflate data.  The header type is detected automatically.  Any information
+  contained in the gzip header is not retained, so applications that need that
+  information should instead use raw inflate, see inflateInit2() below, or
+  inflateBack() and perform their own processing of the gzip header and
+  trailer.
+
+    inflate() returns Z_OK if some progress has been made (more input processed
+  or more output produced), Z_STREAM_END if the end of the compressed data has
+  been reached and all uncompressed output has been produced, Z_NEED_DICT if a
+  preset dictionary is needed at this point, Z_DATA_ERROR if the input data was
+  corrupted (input stream not conforming to the zlib format or incorrect check
+  value), Z_STREAM_ERROR if the stream structure was inconsistent (for example
+  if next_in or next_out was NULL), Z_MEM_ERROR if there was not enough memory,
+  Z_BUF_ERROR if no progress is possible or if there was not enough room in the
+  output buffer when Z_FINISH is used. Note that Z_BUF_ERROR is not fatal, and
+  inflate() can be called again with more input and more output space to
+  continue decompressing. If Z_DATA_ERROR is returned, the application may then
+  call inflateSync() to look for a good compression block if a partial recovery
+  of the data is desired.

+
+     This is another version of deflateInit with more compression options. The

+   the caller.
+
+     The method parameter is the compression method. It must be Z_DEFLATED in
+   this version of the library.
+
+     The windowBits parameter is the base two logarithm of the window size
+   (the size of the history buffer).  It should be in the range 8..15 for this
+   version of the library. Larger values of this parameter result in better
+   compression at the expense of memory usage. The default value is 15 if
+   deflateInit is used instead.
+
+     The memLevel parameter specifies how much memory should be allocated
+   for the internal compression state. memLevel=1 uses minimum memory but
+   is slow and reduces compression ratio; memLevel=9 uses maximum memory
+   for optimal speed. The default value is 8. See zconf.h for total memory
+   usage as a function of windowBits and memLevel.
+
+     The strategy parameter is used to tune the compression algorithm. Use the
+   value Z_DEFAULT_STRATEGY for normal data, Z_FILTERED for data produced by a
+   filter (or predictor), or Z_HUFFMAN_ONLY to force Huffman encoding only (no
+   string match).  Filtered data consists mostly of small values with a
+   somewhat random distribution. In this case, the compression algorithm is
+   tuned to compress them better. The effect of Z_FILTERED is to force more
+   Huffman coding and less string matching; it is somewhat intermediate
+   between Z_DEFAULT and Z_HUFFMAN_ONLY. The strategy parameter only affects
+   the compression ratio but not the correctness of the compressed output even
+   if it is not set appropriately.
+
+      deflateInit2 returns Z_OK if success, Z_MEM_ERROR if there was not enough
+   memory, Z_STREAM_ERROR if a parameter is invalid (such as an invalid

+
+     The windowBits parameter is the base two logarithm of the maximum window
+   size (the size of the history buffer).  It should be in the range 8..15 for
+   this version of the library. The default value is 15 if inflateInit is used
+   instead. windowBits must be greater than or equal to the windowBits value
+   provided to deflateInit2() while compressing, or it must be equal to 15 if
+   deflateInit2() was not used. If a compressed stream with a larger window
+   size is given as input, inflate() will return with the error code
+   Z_DATA_ERROR instead of trying to allocate a larger window.
+
+     windowBits can also be -8..-15 for raw inflate. In this case, -windowBits
+   determines the window size. inflate() will then process raw deflate data,
+   not looking for a zlib or gzip header, not generating a check value, and not
+   looking for any check values for comparison at the end of the stream. This
+   is for use with other formats that use the deflate compressed data format
+   such as zip.  Those formats provide their own check values. If a custom
+   format is developed using the raw deflate format for compressed data, it is
+   recommended that a check value such as an adler32 or a crc32 be applied to
+   the uncompressed data as is done in the zlib, gzip, and zip formats.  For
+   most applications, the zlib format should be used as is. Note that comments
+   above on the use in deflateInit2() applies to the magnitude of windowBits.
+
+     windowBits can also be greater than 15 for optional gzip decoding. Add
+   32 to windowBits to enable zlib and gzip decoding with automatic header
+   detection, or add 16 to decode only the gzip format (the zlib format will

+/* Note that the cx25840 driver requires that the bridge driver calls the
+   v4l2_subdev's init operation in order to load the driver's firmware.
+   Without this the audio standard detection will fail and you will
+   only get mono.
+
+   Since loading the firmware is often problematic when the driver is
+   compiled into the kernel I recommend postponing calling this function
+   until the first open of the video device. Another reason for
+   postponing it is that loading this firmware takes a long time (seconds)
+   due to the slow i2c bus speed. So it will speed up the boot process if

+/* msp3400 routing
+   ===============
+
+   The msp3400 has a complicated routing scheme with many possible
+   combinations. The details are all in the datasheets but I will try
+   to give a short description here.
+
+   Inputs
+   ======
+
+   There are 1) tuner inputs, 2) I2S inputs, 3) SCART inputs. You will have
+   to select which tuner input to use and which SCART input to use. The
+   selected tuner input, the selected SCART input and all I2S inputs go to
+   the DSP (the tuner input first goes through the demodulator).
+
+   The DSP handles things like volume, bass/treble, balance, and some chips
+   have support for surround sound. It has several outputs: MAIN, AUX, I2S
+   and SCART1/2. Each output can select which DSP input to use. So the MAIN
+   output can select the tuner input while at the same time the SCART1 output
+   uses the I2S input.
+
+   Outputs
+   =======
+
+   Most DSP outputs are also the outputs of the msp3400. However, the SCART
+   outputs of the msp3400 can select which input to use: either the SCART1 or
+   SCART2 output from the DSP, or the msp3400 SCART inputs, thus completely
+   bypassing the DSP.
+
+   Summary
+   =======
+
+   So to specify a complete routing scheme for the msp3400 you will have to
+   specify in the 'input' arg of the s_routing function:
+
+   1) which tuner input to use
+   2) which SCART input to use
+   3) which DSP input to use for each DSP output
+
+   And in the 'output' arg of the s_routing function you specify:
+
+   1) which SCART input to use for each SCART output
+
+   Depending on how the msp is wired to the other components you can
+   ignore or mute certain inputs or outputs.
+
+   Also, depending on the msp version only a subset of the inputs or
+   outputs may be present. At the end of this header some tables are
+   added containing a list of what is available for each msp version.
+ */
+
+/* Inputs to the DSP unit: two independent selections have to be made:
+   1) the tuner (SIF) input
+   2) the SCART input
+   Bits 0-2 are used for the SCART input select, bit 3 is used for the tuner
+   input, bits 4-7 are reserved.

+   a DSP input.
+
+   The DSP outputs are: loudspeaker output (aka MAIN), headphones output
+   (aka AUX), SCART1 DA output, SCART2 DA output and an I2S output.
+   There also is a quasi-peak detector output, but that is not used by
+   this driver and is set to the same input as the loudspeaker output.
+   Not all outputs are supported by all msp models. Setting the input
+   of an unsupported output will be ignored by the driver.
+
+   There are up to 16 DSP inputs to choose from, so each output is
+   assigned 4 bits.
+
+   Note: the 44x8G can mix two inputs and feed the result back to the
+   DSP. This is currently not implemented. Also not implemented is the
+   multi-channel capable I2S3 input of the 44x0G. If someone can demonstrate

+  *		this flag.
+  * @is_auto:   If set, then this control selects whether the other cluster
+  *		members are in 'automatic' mode or 'manual' mode. This is
+  *		used for autogain/gain type clusters. Drivers should never
+  *		set this flag directly.

+  *		Drivers should never touch this flag.
+  * @call_notify: If set, then call the handler's notify function whenever the
+  *		control's value changes.
+  * @manual_mode_value: If the is_auto flag is set, then this is the value
+  *		of the auto control that determines if that control is in

+  *		value, then the whole cluster is in manual mode. Drivers should
+  *		never set this flag directly.
+  * @ops:	The control ops.
+  * @type_ops:	The control type ops.

+  *		close to that number, so this is OK. Should we ever need more,
+  *		then this will have to be extended to a u64 or a bit array.

+  *		empty strings ("") correspond to non-existing menu items (this
+  *		is in addition to the menu_skip_mask above). The last entry
+  *		must be NULL.

+  * @cur:	The control's current value.
+  * @val:	The control's new s32 value.
+  * @val64:	The control's new s64 value.
+  * @priv:	The control's private pointer. For use by the driver. It is

+ * Overview:
+ *
+ * Events are subscribed per-filehandle. An event specification consists of a
+ * type and is optionally associated with an object identified through the
+ * 'id' field. So an event is uniquely identified by the (type, id) tuple.
+ *
+ * The v4l2-fh struct has a list of subscribed events. The v4l2_subscribed_event
+ * struct is added to that list, one for every subscribed event.
+ *
+ * Each v4l2_subscribed_event struct ends with an array of v4l2_kevent structs.
+ * This array (ringbuffer, really) is used to store any events raised by the
+ * driver. The v4l2_kevent struct links into the 'available' list of the
+ * v4l2_fh struct so VIDIOC_DQEVENT will know which event to dequeue first.
+ *
+ * Finally, if the event subscription is associated with a particular object
+ * such as a V4L2 control, then that object needs to know about that as well
+ * so that an event can be raised by that object. So the 'node' field can
+ * be used to link the v4l2_subscribed_event struct into a list of that
+ * object.
+ *
+ * So to summarize:
+ *
+ * struct v4l2_fh has two lists: one of the subscribed events, and one of the
+ * pending events.
+ *
+ * struct v4l2_subscribed_event has a ringbuffer of raised (pending) events of
+ * that particular type.
+ *
+ * If struct v4l2_subscribed_event is associated with a specific object, then
+ * that object will have an internal list of struct v4l2_subscribed_event so
+ * it knows who subscribed an event to that object.

+/* Sub-devices are devices that are connected somehow to the main bridge

+   sensors and webcam controllers.
+
+   Usually these devices are controlled through an i2c bus, but other busses
+   may also be used.
+
+   The v4l2_subdev struct provides a way of accessing these devices in a
+   generic manner. Most operations that these sub-devices support fall in
+   a few categories: core ops, audio ops, video ops and tuner ops.
+
+   More categories can be added if needed, although this should remain a
+   limited set (no more than approx. 8 categories).
+
+   Each category has its own set of ops that subdev drivers can implement.
+
+   A subdev driver can leave the pointer to the category ops NULL if
+   it does not implement them (e.g. an audio subdev will generally not
+   implement the video category ops). The exception is the core category:
+   this must always be present.
+
+   These ops are all used internally so it is no problem to change, remove
+   or add ops or move ops from one to another category. Currently these
+   ops are based on the original ioctls, but since ops are not limited to
+   one argument there is room for improvement here once all i2c subdev
+   drivers are converted to use these ops.
+ */
+
+/* Core ops: it is highly recommended to implement at least these ops:
+
+   log_status
+   g_register
+   s_register
+
+   This provides basic debugging support.
+
+   The ioctl ops is meant for generic ioctl-like commands. Depending on
+   the use-case it might be better to use subdev-specific ops (currently
+   not yet implemented) since ops provide proper type-checking.

+ *			the required number of buffers in *num_buffers, the
+ *			required number of planes per buffer in *num_planes; the
+ *			size of each plane should be set in the sizes[] array
+ *			and optional per-plane allocator specific context in the
+ *			alloc_ctxs[] array. When called from VIDIOC_REQBUFS,
+ *			fmt == NULL, the driver has to use the currently
+ *			configured format and *num_buffers is the total number
+ *			of buffers, that are being allocated. When called from
+ *			VIDIOC_CREATE_BUFS, fmt != NULL and it describes the
+ *			target frame format (if the format isn't valid the
+ *			callback must return -EINVAL). In this case *num_buffers
+ *			are being allocated additionally to q->num_buffers.
+ * @wait_prepare:	release any locks taken while calling vb2 functions;
+ *			it is called before an ioctl needs to wait for a new
+ *			buffer to arrive; required to avoid a deadlock in
+ *			blocking access type.
+ * @wait_finish:	reacquire all locks released in the previous callback;
+ *			required to continue operation after sleeping while
+ *			waiting for a new buffer to arrive.
+ * @buf_init:		called once after allocating a buffer (in MMAP case)
+ *			or after acquiring a new USERPTR buffer; drivers may
+ *			perform additional buffer-related initialization;
+ *			initialization failure (return != 0) will prevent
+ *			queue setup from completing successfully; optional.
+ * @buf_prepare:	called every time the buffer is queued from userspace
+ *			and from the VIDIOC_PREPARE_BUF ioctl; drivers may
+ *			perform any initialization required before each
+ *			hardware operation in this callback; drivers can
+ *			access/modify the buffer here as it is still synced for
+ *			the CPU; drivers that support VIDIOC_CREATE_BUFS must
+ *			also validate the buffer size; if an error is returned,
+ *			the buffer will not be queued in driver; optional.
+ * @buf_finish:		called before every dequeue of the buffer back to
+ *			userspace; the buffer is synced for the CPU, so drivers
+ *			can access/modify the buffer contents; drivers may
+ *			perform any operations required before userspace
+ *			accesses the buffer; optional. The buffer state can be
+ *			one of the following: DONE and ERROR occur while
+ *			streaming is in progress, and the PREPARED state occurs
+ *			when the queue has been canceled and all pending
+ *			buffers are being returned to their default DEQUEUED
+ *			state. Typically you only have to do something if the
+ *			state is VB2_BUF_STATE_DONE, since in all other cases
+ *			the buffer contents will be ignored anyway.
+ * @buf_cleanup:	called once before the buffer is freed; drivers may
+ *			perform any additional cleanup; optional.
+ * @start_streaming:	called once to enter 'streaming' state; the driver may
+ *			receive buffers with @buf_queue callback before
+ *			@start_streaming is called; the driver gets the number
+ *			of already queued buffers in count parameter; driver
+ *			can return an error if hardware fails, in that case all
+ *			buffers that have been already given by the @buf_queue
+ *			callback are to be returned by the driver by calling
+ *			@vb2_buffer_done(VB2_BUF_STATE_QUEUED).
+ *			If you need a minimum number of buffers before you can
+ *			start streaming, then set @min_buffers_needed in the
+ *			vb2_queue structure. If that is non-zero then
+ *			start_streaming won't be called until at least that
+ *			many buffers have been queued up by userspace.
+ * @stop_streaming:	called when 'streaming' state must be disabled; driver
+ *			should stop any DMA transactions or wait until they
+ *			finish and give back all buffers it got from buf_queue()
+ *			callback by calling @vb2_buffer_done() with either
+ *			VB2_BUF_STATE_DONE or VB2_BUF_STATE_ERROR; may use
+ *			vb2_wait_for_all_buffers() function
+ * @buf_queue:		passes buffer vb to the driver; driver may start
+ *			hardware operation on this buffer; driver should give
+ *			the buffer back by calling vb2_buffer_done() function;
+ *			it is allways called after calling STREAMON ioctl;
+ *			might be called before start_streaming callback if user
+ *			pre-queued buffers before calling STREAMON.

+ *		This field is not used by the videobuf2 core API, but it allows
+ *		drivers to easily associate an owner filehandle with the queue.
+ * @ops:	driver-specific callbacks
+ * @mem_ops:	memory allocator specific callbacks
+ * @drv_priv:	driver private data
+ * @buf_struct_size: size of the driver-specific buffer structure;
+ *		"0" indicates the driver doesn't want to use a custom buffer
+ *		structure type, so sizeof(struct vb2_buffer) will is used
+ * @timestamp_flags: Timestamp flags; V4L2_BUF_FLAG_TIMESTAMP_* and
+ *		V4L2_BUF_FLAG_TSTAMP_SRC_*
+ * @gfp_flags:	additional gfp flags used when allocating the buffers.
+ *		Typically this is 0, but it may be e.g. GFP_DMA or __GFP_DMA32
+ *		to force the buffer allocation to a specific memory zone.
+ * @min_buffers_needed: the minimum number of buffers needed before
+ *		start_streaming() can be called. Used when a DMA engine
+ *		cannot be started unless at least this number of buffers
+ *		have been queued into the driver.
+ *
+ * @mmap_lock:	private mutex used when buffers are allocated/freed/mmapped
+ * @memory:	current memory type used
+ * @bufs:	videobuf buffer structures
+ * @num_buffers: number of allocated/used buffers
+ * @queued_list: list of buffers currently queued from userspace
+ * @queued_count: number of buffers queued and ready for streaming.
+ * @owned_by_drv_count: number of buffers owned by the driver
+ * @done_list:	list of buffers ready to be dequeued to userspace
+ * @done_lock:	lock to protect done_list list
+ * @done_wq:	waitqueue for processes waiting for buffers ready to be dequeued
+ * @alloc_ctx:	memory type/allocator-specific contexts for each plane
+ * @streaming:	current streaming state
+ * @start_streaming_called: start_streaming() was called successfully and we
+ *		started streaming.
+ * @error:	a fatal error occurred on the queue
+ * @waiting_for_buffers: used in poll() to check if vb2 is still waiting for
+ *		buffers. Only set for capture queues if qbuf has not yet been
+ *		called since poll() needs to return POLLERR in that situation.
+ * @fileio:	file io emulator internal data, used only if emulator is active
+ * @threadio:	thread io internal data, used only if thread is active

+ * and can be dereferenced. So you can use its locks, local variables and any

+ * Before accessing runtime data, you _must_ lock the object and then check that
+ * it is still running. As soon as you release the locks, the connection might

+ * On the other hand, hci_conn_hold() and hci_conn_drop() are used to control

+ * hci_conn object calls this to prevent the connection from disappearing. As
+ * long as you hold a device, you must also guarantee that you have a valid
+ * reference to the device via hci_conn_get() (or the initial reference from
+ * hci_conn_add()).
+ * The hold()/drop() ref-count is known to drop below 0 sometimes, which doesn't
+ * break because nobody cares for that. But this means, we cannot use
+ * _get()/_drop() in it, but require the caller to have a valid ref (FIXME).

+ * DOC: Introduction
+ *
+ * cfg80211 is the configuration API for 802.11 devices in Linux. It bridges
+ * userspace and drivers, and offers some utility functionality associated
+ * with 802.11. cfg80211 must, directly or indirectly via mac80211, be used
+ * by all modern wireless drivers in Linux, so that they offer a consistent
+ * API through nl80211. For backward compatibility, cfg80211 also offers
+ * wireless extensions to userspace, but hides them from drivers completely.
+ *
+ * Additionally, cfg80211 contains code to help enforce regulatory spectrum
+ * use restrictions.
+ */
+
+
+/**
+ * DOC: Device registration
+ *
+ * In order for a driver to use cfg80211, it must register the hardware device
+ * with cfg80211. This happens through a number of hardware capability structs
+ * described below.
+ *
+ * The fundamental structure for each device is the 'wiphy', of which each
+ * instance describes a physical wireless device connected to the system. Each
+ * such wiphy can have zero, one, or many virtual interfaces associated with
+ * it, which need to be identified as such by pointing the network interface's
+ * @ieee80211_ptr pointer to a &struct wireless_dev which further describes
+ * the wireless part of the interface, normally this struct is embedded in the
+ * network interface's private data area. Drivers can optionally allow creating
+ * or destroying virtual interfaces on the fly, but without at least one or the
+ * ability to create some the wireless device isn't useful.
+ *
+ * Each wiphy structure contains device capability information, and also has
+ * a pointer to the various operations the driver offers. The definitions and
+ * structures here describe these capabilities in detail.

+ * a bit of helper functionality. To start a scan, the scan operation will

+ * channels to scan, and the SSIDs to send probe requests for (including the
+ * wildcard, if desired). A passive scan is indicated by having no SSIDs to
+ * probe. Additionally, a scan request may contain extra information elements
+ * that should be added to the probe request. The IEs are guaranteed to be
+ * well-formed, and will not exceed the maximum length the driver advertised
+ * in the wiphy structure.
+ *
+ * When scanning finds a BSS, cfg80211 needs to be notified of that, because
+ * it is responsible for maintaining the BSS list; the driver should not
+ * maintain a list itself. For this notification, various functions exist.
+ *
+ * Since drivers do not maintain a BSS list, there are also a number of
+ * functions to search for a BSS and obtain information about it from the
+ * BSS structure cfg80211 maintains. The BSS list is also made available

+ * @add_virtual_intf: create a new virtual interface with the given name,
+ *	must set the struct wireless_dev's iftype. Beware: You must create
+ *	the new netdev in the wiphy's network namespace! Returns the struct

+ *
+ * @change_virtual_intf: change type/configuration of virtual interface,

+ *	The mask is a bitfield which tells us which parameters to
+ *	set, and which to leave alone.
+ *
+ * @change_bss: Modify parameters for a given BSS.
+ *
+ * @set_txq_params: Set TX queue parameters
+ *
+ * @libertas_set_mesh_channel: Only for backward compatibility for libertas,
+ *	as it doesn't implement join_mesh and needs to set the channel to
+ *	join the mesh instead.
+ *
+ * @set_monitor_channel: Set the monitor mode channel for the device. If other
+ *	interfaces are active this callback should reject the configuration.
+ *	If no interfaces are active or the device is down, the channel should
+ *	be stored for when a monitor interface becomes active.
+ *
+ * @scan: Request to do a scan. If returning zero, the scan request is given
+ *	the driver, and will be valid until passed to cfg80211_scan_done().
+ *	For scan results, call cfg80211_inform_bss(); you can call this outside

+ *	(invoked with the wireless_dev mutex held)
+ * @disconnect: Disconnect from the BSS/ESS.
+ *	(invoked with the wireless_dev mutex held)

+ * @join_ibss: Join the specified IBSS (or create if necessary). Once done, call
+ *	cfg80211_ibss_joined(), also call that function when changing BSSID due
+ *	to a merge.
+ *	(invoked with the wireless_dev mutex held)

+ *
+ * @set_mcast_rate: Set the specified multicast rate (only if vif is in ADHOC or

+ *
+ * @set_wiphy_params: Notify that wiphy parameters have changed;
+ *	@changed bitfield (see &enum wiphy_params_flags) describes which values
+ *	have changed. The actual parameter values are available in
+ *	struct wiphy. If returning an error, no value should be changed.
+ *
+ * @set_tx_power: set the transmit power according to the parameters,
+ *	the power passed is in mBm, to get dBm use MBM_TO_DBM(). The
+ *	wdev may be %NULL if power was set for the wiphy, and will
+ *	always be %NULL unless the driver supports per-vif TX power
+ *	(as advertised by the nl80211 feature flag.)
+ * @get_tx_power: store the current TX power into the dbm variable;
+ *	return 0 if successful
+ *
+ * @set_wds_peer: set the WDS peer for a WDS interface
+ *
+ * @rfkill_poll: polls the hw rfkill line, use cfg80211 reporting
+ *	functions to adjust rfkill hw state
+ *
+ * @dump_survey: get site survey information.
+ *
+ * @remain_on_channel: Request the driver to remain awake on the specified
+ *	channel for the specified duration to complete an off-channel
+ *	operation (e.g., public action frame exchange). When the driver is
+ *	ready on the requested channel, it must indicate this with an event
+ *	notification by calling cfg80211_ready_on_channel().
+ * @cancel_remain_on_channel: Cancel an on-going remain-on-channel operation.
+ *	This allows the operation to be terminated prior to timeout based on
+ *	the duration value.
+ * @mgmt_tx: Transmit a management frame.
+ * @mgmt_tx_cancel_wait: Cancel the wait time from transmitting a management
+ *	frame on another channel
+ *
+ * @testmode_cmd: run a test mode command; @wdev may be %NULL
+ * @testmode_dump: Implement a test mode dump. The cb->args[2] and up may be
+ *	used by the function, but 0 and 1 must not be touched. Additionally,
+ *	return error codes other than -ENOBUFS and -ENOENT will terminate the
+ *	dump and return to userspace with an error, so be careful. If any data
+ *	was passed in from userspace then the data/len arguments will be present
+ *	and point to the data contained in %NL80211_ATTR_TESTDATA.
+ *
+ * @set_bitrate_mask: set the bitrate mask configuration
+ *
+ * @set_pmksa: Cache a PMKID for a BSSID. This is mostly useful for fullmac
+ *	devices running firmwares capable of generating the (re) association
+ *	RSN IE. It allows for faster roaming between WPA2 BSSIDs.
+ * @del_pmksa: Delete a cached PMKID.
+ * @flush_pmksa: Flush all cached PMKIDs.
+ * @set_power_mgmt: Configure WLAN power management. A timeout value of -1
+ *	allows the driver to adjust the dynamic ps timeout value.
+ * @set_cqm_rssi_config: Configure connection quality monitor RSSI threshold.
+ * @set_cqm_txe_config: Configure connection quality monitor TX error
+ *	thresholds.
+ * @sched_scan_start: Tell the driver to start a scheduled scan.
+ * @sched_scan_stop: Tell the driver to stop an ongoing scheduled scan. This
+ *	call must stop the scheduled scan and be ready for starting a new one
+ *	before it returns, i.e. @sched_scan_start may be called immediately
+ *	after that again and should not fail in that case. The driver should
+ *	not call cfg80211_sched_scan_stopped() for a requested stop (when this
+ *	method returns 0.)
+ *
+ * @mgmt_frame_register: Notify driver that a management frame type was
+ *	registered. Note that this callback may not sleep, and cannot run
+ *	concurrently with itself.
+ *
+ * @set_antenna: Set antenna configuration (tx_ant, rx_ant) on the device.
+ *	Parameters are bitmaps of allowed antennas to use for TX/RX. Drivers may
+ *	reject TX/RX mask combinations they cannot support by returning -EINVAL
+ *	(also see nl80211.h @NL80211_ATTR_WIPHY_ANTENNA_TX).
+ *
+ * @get_antenna: Get current antenna configuration from device (tx_ant, rx_ant).
+ *
+ * @tdls_mgmt: Transmit a TDLS management frame.
+ * @tdls_oper: Perform a high-level TDLS operation (e.g. TDLS link setup).
+ *
+ * @probe_client: probe an associated client, must return a cookie that it
+ *	later passes to cfg80211_probe_status().
+ *
+ * @set_noack_map: Set the NoAck Map for the TIDs.
+ *
+ * @get_channel: Get the current operating channel for the virtual interface.
+ *	For monitor interfaces, it should return %NULL unless there's a single
+ *	current monitoring channel.
+ *
+ * @start_p2p_device: Start the given P2P device.
+ * @stop_p2p_device: Stop the given P2P device.
+ *
+ * @set_mac_acl: Sets MAC address control list in AP and P2P GO mode.
+ *	Parameters include ACL policy, an array of MAC address of stations
+ *	and the number of MAC addresses. If there is already a list in driver
+ *	this new list replaces the existing one. Driver has to clear its ACL
+ *	when number of MAC addresses entries is passed as 0. Drivers which
+ *	advertise the support for MAC based ACL have to implement this callback.
+ *
+ * @start_radar_detection: Start radar detection in the driver.
+ *
+ * @update_ft_ies: Provide updated Fast BSS Transition information to the
+ *	driver. If the SME is in the driver/firmware, this information can be
+ *	used in building Authentication and Reassociation Request frames.
+ *
+ * @crit_proto_start: Indicates a critical protocol needs more link reliability
+ *	for a given duration (milliseconds). The protocol is provided so the
+ *	driver can take the most appropriate actions.
+ * @crit_proto_stop: Indicates critical protocol no longer needs increased link
+ *	reliability. This operation can not fail.
+ * @set_coalesce: Set coalesce parameters.
+ *
+ * @channel_switch: initiate channel-switch procedure (with CSA). Driver is
+ *	responsible for veryfing if the switch is possible. Since this is
+ *	inherently tricky driver may decide to disconnect an interface later
+ *	with cfg80211_stop_iface(). This doesn't mean driver can accept
+ *	everything. It should do it's best to verify requests and reject them
+ *	as soon as possible.
+ *
+ * @set_qos_map: Set QoS mapping information to the driver
+ *
+ * @set_ap_chanwidth: Set the AP (including P2P GO) mode channel width for the
+ *	given interface This is used e.g. for dynamic HT 20/40 MHz channel width
+ *	changes during the lifetime of the BSS.
+ *
+ * @add_tx_ts: validate (if admitted_time is 0) or add a TX TS to the device
+ *	with the given parameters; action frame exchange has been handled by
+ *	userspace so this just has to modify the TX path to take the TS into
+ *	account.
+ *	If the admitted time is 0 just validate the parameters to make sure
+ *	the session can be created at all; it is valid to just always return
+ *	success for that but that may result in inefficient behaviour (handshake
+ *	with the peer followed by immediate teardown when the addition is later
+ *	rejected)
+ * @del_tx_ts: remove an existing TX TS
+ *
+ * @join_ocb: join the OCB network with the specified parameters
+ *	(invoked with the wireless_dev mutex held)
+ * @leave_ocb: leave the current OCB network
+ *	(invoked with the wireless_dev mutex held)
+ *
+ * @tdls_channel_switch: Start channel-switching with a TDLS peer. The driver
+ *	is responsible for continually initiating channel-switching operations
+ *	and returning to the base channel for communication with the AP.
+ * @tdls_cancel_channel_switch: Stop channel-switching with a TDLS peer. Both
+ *	peers must be on the base channel when the call completes.

+ * The device state field, defines the initial state in which the
+ * device will come up. In the dn_dev structure, it is the actual
+ * state.
+ *
+ * Things have changed here. I've killed timer1 since it's a user space
+ * issue for a user space routing deamon to sort out. The kernel does
+ * not need to be bothered with it.
+ *
+ * Timers:
+ * t2 - Rate limit timer, min time between routing and hello messages
+ * t3 - Hello timer, send hello messages when it expires
+ *
+ * Callbacks:
+ * up() - Called to initialize device, return value can veto use of
+ *        device with DECnet.

+ *
+ * The interesting point, is test #2.  This is what an FTP server does
+ * all day.  To optimize this case we use a specific flag bit defined
+ * below.  As we add sockets to a bind bucket list, we perform a
+ * check of: (newsk->sk_reuse && (newsk->sk_state != TCP_LISTEN))
+ * As long as all sockets added to a bind bucket pass this test,

+ * for this flag bit, if it is set and the socket trying to bind has
+ * sk->sk_reuse set, we don't even have to walk the owners list at all,
+ * we return that it is ok to bind this socket to the requested local port.

+ * implementation (ie. current FreeBSD etc.) the entire list of ports
+ * must be walked for each data port opened by an ftp server.  Needless
+ * to say, this does not scale at all.  With a couple thousand FTP

+/************************** DOCUMENTATION **************************/
+/*
+ * Initial driver API (1996 -> onward) :
+ * -----------------------------------
+ * The initial API just sends the IOCTL request received from user space
+ * to the driver (via the driver ioctl handler). The driver has to
+ * handle all the rest...
+ *
+ * The initial API also defines a specific handler in struct net_device
+ * to handle wireless statistics.
+ *
+ * The initial APIs served us well and has proven a reasonably good design.
+ * However, there is a few shortcommings :
+ *	o No events, everything is a request to the driver.
+ *	o Large ioctl function in driver with gigantic switch statement
+ *	  (i.e. spaghetti code).
+ *	o Driver has to mess up with copy_to/from_user, and in many cases
+ *	  does it unproperly. Common mistakes are :
+ *		* buffer overflows (no checks or off by one checks)
+ *		* call copy_to/from_user with irq disabled
+ *	o The user space interface is tied to ioctl because of the use
+ *	  copy_to/from_user.
+ *
+ * New driver API (2002 -> onward) :
+ * -------------------------------
+ * The new driver API is just a bunch of standard functions (handlers),
+ * each handling a specific Wireless Extension. The driver just export
+ * the list of handler it supports, and those will be called apropriately.
+ *
+ * I tried to keep the main advantage of the previous API (simplicity,
+ * efficiency and light weight), and also I provide a good dose of backward
+ * compatibility (most structures are the same, driver can use both API
+ * simultaneously, ...).
+ * Hopefully, I've also addressed the shortcomming of the initial API.
+ *
+ * The advantage of the new API are :
+ *	o Handling of Extensions in driver broken in small contained functions
+ *	o Tighter checks of ioctl before calling the driver
+ *	o Flexible commit strategy (at least, the start of it)
+ *	o Backward compatibility (can be mixed with old API)
+ *	o Driver doesn't have to worry about memory and user-space issues
+ * The last point is important for the following reasons :
+ *	o You are now able to call the new driver API from any API you
+ *		want (including from within other parts of the kernel).
+ *	o Common mistakes are avoided (buffer overflow, user space copy
+ *		with irq disabled and so on).
+ *
+ * The Drawback of the new API are :
+ *	o bloat (especially kernel)
+ *	o need to migrate existing drivers to new API
+ * My initial testing shows that the new API adds around 3kB to the kernel
+ * and save between 0 and 5kB from a typical driver.
+ * Also, as all structures and data types are unchanged, the migration is
+ * quite straightforward (but tedious).
+ *
+ * ---
+ *
+ * The new driver API is defined below in this file. User space should
+ * not be aware of what's happening down there...
+ *
+ * A new kernel wrapper is in charge of validating the IOCTLs and calling
+ * the appropriate driver handler. This is implemented in :
+ *	# net/core/wireless.c
+ *
+ * The driver export the list of handlers in :
+ *	# include/linux/netdevice.h (one place)
+ *
+ * The new driver API is available for WIRELESS_EXT >= 13.
+ * Good luck with migration to the new API ;-)
+ */
+
+/* ---------------------- THE IMPLEMENTATION ---------------------- */
+/*
+ * Some of the choice I've made are pretty controversials. Defining an
+ * API is very much weighting compromises. This goes into some of the
+ * details and the thinking behind the implementation.
+ *
+ * Implementation goals :
+ * --------------------
+ * The implementation goals were as follow :
+ *	o Obvious : you should not need a PhD to understand what's happening,
+ *		the benefit is easier maintenance.
+ *	o Flexible : it should accommodate a wide variety of driver
+ *		implementations and be as flexible as the old API.
+ *	o Lean : it should be efficient memory wise to minimise the impact
+ *		on kernel footprint.
+ *	o Transparent to user space : the large number of user space
+ *		applications that use Wireless Extensions should not need
+ *		any modifications.
+ *
+ * Array of functions versus Struct of functions
+ * ---------------------------------------------
+ * 1) Having an array of functions allow the kernel code to access the
+ * handler in a single lookup, which is much more efficient (think hash
+ * table here).
+ * 2) The only drawback is that driver writer may put their handler in
+ * the wrong slot. This is trivial to test (I set the frequency, the
+ * bitrate changes). Once the handler is in the proper slot, it will be
+ * there forever, because the array is only extended at the end.
+ * 3) Backward/forward compatibility : adding new handler just require
+ * extending the array, so you can put newer driver in older kernel
+ * without having to patch the kernel code (and vice versa).
+ *
+ * All handler are of the same generic type
+ * ----------------------------------------
+ * That's a feature !!!
+ * 1) Having a generic handler allow to have generic code, which is more
+ * efficient. If each of the handler was individually typed I would need
+ * to add a big switch in the kernel (== more bloat). This solution is
+ * more scalable, adding new Wireless Extensions doesn't add new code.
+ * 2) You can use the same handler in different slots of the array. For
+ * hardware, it may be more efficient or logical to handle multiple
+ * Wireless Extensions with a single function, and the API allow you to
+ * do that. (An example would be a single record on the card to control
+ * both bitrate and frequency, the handler would read the old record,
+ * modify it according to info->cmd and rewrite it).
+ *
+ * Functions prototype uses union iwreq_data
+ * -----------------------------------------
+ * Some would have preferred functions defined this way :
+ *	static int mydriver_ioctl_setrate(struct net_device *dev, 
+ *					  long rate, int auto)
+ * 1) The kernel code doesn't "validate" the content of iwreq_data, and
+ * can't do it (different hardware may have different notion of what a
+ * valid frequency is), so we don't pretend that we do it.
+ * 2) The above form is not extendable. If I want to add a flag (for
+ * example to distinguish setting max rate and basic rate), I would
+ * break the prototype. Using iwreq_data is more flexible.
+ * 3) Also, the above form is not generic (see above).
+ * 4) I don't expect driver developper using the wrong field of the
+ * union (Doh !), so static typechecking doesn't add much value.
+ * 5) Lastly, you can skip the union by doing :
+ *	static int mydriver_ioctl_setrate(struct net_device *dev,
+ *					  struct iw_request_info *info,
+ *					  struct iw_param *rrq,
+ *					  char *extra)
+ * And then adding the handler in the array like this :
+ *        (iw_handler) mydriver_ioctl_setrate,             // SIOCSIWRATE
+ *
+ * Using functions and not a registry
+ * ----------------------------------
+ * Another implementation option would have been for every instance to
+ * define a registry (a struct containing all the Wireless Extensions)
+ * and only have a function to commit the registry to the hardware.
+ * 1) This approach can be emulated by the current code, but not
+ * vice versa.
+ * 2) Some drivers don't keep any configuration in the driver, for them
+ * adding such a registry would be a significant bloat.
+ * 3) The code to translate from Wireless Extension to native format is
+ * needed anyway, so it would not reduce significantely the amount of code.
+ * 4) The current approach only selectively translate Wireless Extensions
+ * to native format and only selectively set, whereas the registry approach
+ * would require to translate all WE and set all parameters for any single
+ * change.
+ * 5) For many Wireless Extensions, the GET operation return the current
+ * dynamic value, not the value that was set.
+ *
+ * This header is <net/iw_handler.h>
+ * ---------------------------------
+ * 1) This header is kernel space only and should not be exported to
+ * user space. Headers in "include/linux/" are exported, headers in
+ * "include/net/" are not.
+ *
+ * Mixed 32/64 bit issues
+ * ----------------------
+ * The Wireless Extensions are designed to be 64 bit clean, by using only
+ * datatypes with explicit storage size.
+ * There are some issues related to kernel and user space using different
+ * memory model, and in particular 64bit kernel with 32bit user space.
+ * The problem is related to struct iw_point, that contains a pointer
+ * that *may* need to be translated.
+ * This is quite messy. The new API doesn't solve this problem (it can't),
+ * but is a step in the right direction :
+ * 1) Meta data about each ioctl is easily available, so we know what type
+ * of translation is needed.
+ * 2) The move of data between kernel and user space is only done in a single
+ * place in the kernel, so adding specific hooks in there is possible.
+ * 3) In the long term, it allows to move away from using ioctl as the
+ * user space API.
+ *
+ * So many comments and so few code
+ * --------------------------------
+ * That's a feature. Comments won't bloat the resulting kernel binary.

+ * tasklet function.

+ * hardware.
+ *
+ * There are, however, various exceptions to this rule for advanced features:
+ *
+ * The first exception is for hardware encryption and decryption offload
+ * where the IV/ICV may or may not be generated in hardware.
+ *
+ * Secondly, when the hardware handles fragmentation, the frame handed to

+ * helpers for sanity checking. Drivers must ensure all work added onto the
+ * mac80211 workqueue should be cancelled on the driver stop() callback.
+ *
+ * mac80211 will flushed the workqueue upon interface removal and during

+ *

+
+/**
+ * DOC: mac80211 software tx queueing
+ *
+ * mac80211 provides an optional intermediate queueing implementation designed
+ * to allow the driver to keep hardware queues short and provide some fairness
+ * between different stations/interfaces.
+ * In this model, the driver pulls data frames from the mac80211 queue instead
+ * of letting mac80211 push them via drv_tx().
+ * Other frames (e.g. control or management) are still pushed using drv_tx().
+ *
+ * Drivers indicate that they use this model by implementing the .wake_tx_queue
+ * driver operation.
+ *
+ * Intermediate queues (struct ieee80211_txq) are kept per-sta per-tid, with a
+ * single per-vif queue for multicast data frames.
+ *
+ * The driver is expected to initialize its private per-queue data for stations
+ * and interfaces in the .add_interface and .sta_add ops.
+ *
+ * The driver can't access the queue directly. To dequeue a frame, it calls
+ * ieee80211_tx_dequeue(). Whenever mac80211 adds a new frame to a queue, it
+ * calls the .wake_tx_queue driver op.
+ *
+ * For AP powersave TIM handling, the driver only needs to indicate if it has
+ * buffered packets in the driver specific data structures by calling
+ * ieee80211_sta_set_buffered(). For frames buffered in the ieee80211_txq
+ * struct, mac80211 sets the appropriate TIM PVB bits and calls
+ * .release_buffered_frames().
+ * In that callback the driver is therefore expected to release its own
+ * buffered frames and afterwards also frames from the ieee80211_txq (obtained
+ * via the usual ieee80211_tx_dequeue).

+ * @beacon_rate: associated AP's beacon TX rate
+ * @mcast_rate: per-band multicast rate index + 1 (0: disabled)
+ * @bssid: The BSSID for this BSS
+ * @enable_beacon: whether beaconing should be enabled or not
+ * @chandef: Channel definition for this BSS -- the hardware might be
+ *	configured a higher bandwidth than this BSS uses, for example.
+ * @ht_operation_mode: HT operation mode like in &struct ieee80211_ht_operation.
+ *	This field is only valid when the channel type is one of the HT types.
+ * @cqm_rssi_thold: Connection quality monitor RSSI threshold, a zero value
+ *	implies disabled
+ * @cqm_rssi_hyst: Connection quality monitor RSSI hysteresis
+ * @arp_addr_list: List of IPv4 addresses for hardware ARP filtering. The
+ *	may filter ARP queries targeted for other addresses than listed here.
+ *	The driver must allow ARP queries targeted for all address listed here
+ *	to pass through. An empty list implies no ARP queries need to pass.
+ * @arp_addr_cnt: Number of addresses currently on the list. Note that this
+ *	may be larger than %IEEE80211_BSS_ARP_ADDR_LIST_LEN (the arp_addr_list
+ *	array size), it's up to the driver what to do in that case.
+ * @qos: This is a QoS-enabled BSS.
+ * @idle: This interface is idle. There's also a global idle flag in the
+ *	hardware config which may be more appropriate depending on what
+ *	your driver/device needs to do.
+ * @ps: power-save mode (STA only). This flag is NOT affected by
+ *	offchannel/dynamic_ps operations.
+ * @ssid: The SSID of the current vif. Valid in AP and IBSS mode.
+ * @ssid_len: Length of SSID given in @ssid.
+ * @hidden_ssid: The SSID of the current vif is hidden. Only valid in AP-mode.
+ * @txpower: TX power in dBm
+ * @txpower_type: TX power adjustment used to control per packet Transmit
+ *	Power Control (TPC) in lower driver for the current vif. In particular

+ * enum mac80211_tx_info_flags - flags to describe transmission information/status
+ *
+ * These flags are used with the @flags member of &ieee80211_tx_info.
+ *
+ * @IEEE80211_TX_CTL_REQ_TX_STATUS: require TX status callback for this frame.
+ * @IEEE80211_TX_CTL_ASSIGN_SEQ: The driver has to assign a sequence
+ *	number to this frame, taking care of not overwriting the fragment
+ *	number and increasing the sequence number only when the
+ *	IEEE80211_TX_CTL_FIRST_FRAGMENT flag is set. mac80211 will properly
+ *	assign sequence numbers to QoS-data frames but cannot do so correctly
+ *	for non-QoS-data and management frames because beacons need them from
+ *	that counter as well and mac80211 cannot guarantee proper sequencing.
+ *	If this flag is set, the driver should instruct the hardware to
+ *	assign a sequence number to the frame or assign one itself. Cf. IEEE
+ *	802.11-2007 7.1.3.4.1 paragraph 3. This flag will always be set for
+ *	beacons and always be clear for frames without a sequence number field.
+ * @IEEE80211_TX_CTL_NO_ACK: tell the low level not to wait for an ack
+ * @IEEE80211_TX_CTL_CLEAR_PS_FILT: clear powersave filter for destination
+ *	station
+ * @IEEE80211_TX_CTL_FIRST_FRAGMENT: this is a first fragment of the frame
+ * @IEEE80211_TX_CTL_SEND_AFTER_DTIM: send this frame after DTIM beacon
+ * @IEEE80211_TX_CTL_AMPDU: this frame should be sent as part of an A-MPDU
+ * @IEEE80211_TX_CTL_INJECTED: Frame was injected, internal to mac80211.
+ * @IEEE80211_TX_STAT_TX_FILTERED: The frame was not transmitted
+ *	because the destination STA was in powersave mode. Note that to
+ *	avoid race conditions, the filter must be set by the hardware or
+ *	firmware upon receiving a frame that indicates that the station
+ *	went to sleep (must be done on device to filter frames already on
+ *	the queue) and may only be unset after mac80211 gives the OK for
+ *	that by setting the IEEE80211_TX_CTL_CLEAR_PS_FILT (see above),
+ *	since only then is it guaranteed that no more frames are in the
+ *	hardware queue.
+ * @IEEE80211_TX_STAT_ACK: Frame was acknowledged
+ * @IEEE80211_TX_STAT_AMPDU: The frame was aggregated, so status
+ * 	is for the whole aggregation.
+ * @IEEE80211_TX_STAT_AMPDU_NO_BACK: no block ack was returned,
+ * 	so consider using block ack request (BAR).
+ * @IEEE80211_TX_CTL_RATE_CTRL_PROBE: internal to mac80211, can be
+ *	set by rate control algorithms to indicate probe rate, will
+ *	be cleared for fragmented frames (except on the last fragment)
+ * @IEEE80211_TX_INTFL_OFFCHAN_TX_OK: Internal to mac80211. Used to indicate
+ *	that a frame can be transmitted while the queues are stopped for
+ *	off-channel operation.
+ * @IEEE80211_TX_INTFL_NEED_TXPROCESSING: completely internal to mac80211,
+ *	used to indicate that a pending frame requires TX processing before
+ *	it can be sent out.
+ * @IEEE80211_TX_INTFL_RETRIED: completely internal to mac80211,
+ *	used to indicate that a frame was already retried due to PS
+ * @IEEE80211_TX_INTFL_DONT_ENCRYPT: completely internal to mac80211,
+ *	used to indicate frame should not be encrypted
+ * @IEEE80211_TX_CTL_NO_PS_BUFFER: This frame is a response to a poll
+ *	frame (PS-Poll or uAPSD) or a non-bufferable MMPDU and must
+ *	be sent although the station is in powersave mode.
+ * @IEEE80211_TX_CTL_MORE_FRAMES: More frames will be passed to the
+ *	transmit function after the current frame, this can be used
+ *	by drivers to kick the DMA queue only if unset or when the
+ *	queue gets full.
+ * @IEEE80211_TX_INTFL_RETRANSMISSION: This frame is being retransmitted
+ *	after TX status because the destination was asleep, it must not
+ *	be modified again (no seqno assignment, crypto, etc.)
+ * @IEEE80211_TX_INTFL_MLME_CONN_TX: This frame was transmitted by the MLME
+ *	code for connection establishment, this indicates that its status
+ *	should kick the MLME state machine.
+ * @IEEE80211_TX_INTFL_NL80211_FRAME_TX: Frame was requested through nl80211
+ *	MLME command (internal to mac80211 to figure out whether to send TX
+ *	status to user space)
+ * @IEEE80211_TX_CTL_LDPC: tells the driver to use LDPC for this frame
+ * @IEEE80211_TX_CTL_STBC: Enables Space-Time Block Coding (STBC) for this
+ *	frame and selects the maximum number of streams that it can use.
+ * @IEEE80211_TX_CTL_TX_OFFCHAN: Marks this packet to be transmitted on
+ *	the off-channel channel when a remain-on-channel offload is done
+ *	in hardware -- normal packets still flow and are expected to be
+ *	handled properly by the device.
+ * @IEEE80211_TX_INTFL_TKIP_MIC_FAILURE: Marks this packet to be used for TKIP
+ *	testing. It will be sent out with incorrect Michael MIC key to allow
+ *	TKIP countermeasures to be tested.
+ * @IEEE80211_TX_CTL_NO_CCK_RATE: This frame will be sent at non CCK rate.
+ *	This flag is actually used for management frame especially for P2P
+ *	frames not being sent at CCK rate in 2GHz band.
+ * @IEEE80211_TX_STATUS_EOSP: This packet marks the end of service period,
+ *	when its status is reported the service period ends. For frames in
+ *	an SP that mac80211 transmits, it is already set; for driver frames
+ *	the driver may set this flag. It is also used to do the same for
+ *	PS-Poll responses.
+ * @IEEE80211_TX_CTL_USE_MINRATE: This frame will be sent at lowest rate.
+ *	This flag is used to send nullfunc frame at minimum rate when
+ *	the nullfunc is used for connection monitoring purpose.
+ * @IEEE80211_TX_CTL_DONTFRAG: Don't fragment this packet even if it
+ *	would be fragmented by size (this is optional, only used for
+ *	monitor injection).
+ * @IEEE80211_TX_STAT_NOACK_TRANSMITTED: A frame that was marked with
+ *	IEEE80211_TX_CTL_NO_ACK has been successfully transmitted without
+ *	any errors (like issues specific to the driver/HW).
+ *	This flag must not be set for frames that don't request no-ack
+ *	behaviour with IEEE80211_TX_CTL_NO_ACK.
+ *
+ * Note: If you have to add new flags to the enumeration, then don't
+ *	 forget to update %IEEE80211_TX_TEMPORARY_FLAGS when necessary.

+ * @RX_FLAG_NO_SIGNAL_VAL: The signal strength value is not present.

+ * @RX_FLAG_AMPDU_DETAILS: A-MPDU details are known, in particular the reference

+ * @RX_FLAG_AMPDU_REPORT_ZEROLEN: driver reports 0-length subframes

+ *	for power saving stations in the hardware/firmware and others
+ *	rely on the host system for such buffering. This option is used

+ *
+ * @IEEE80211_HW_SW_CRYPTO_CONTROL: The driver wants to control which of the

+ *
+ * The set_key() callback in the &struct ieee80211_ops for a given
+ * device is called to enable hardware acceleration of encryption and
+ * decryption. The callback takes a @sta parameter that will be NULL
+ * for default keys or keys used for transmission only, or point to
+ * the station information for the peer for individual keys.
+ * Multiple transmission keys with the same key index may be used when
+ * VLANs are configured for an access point.
+ *
+ * When transmitting, the TX control data will use the @hw_key_idx
+ * selected by the driver by modifying the &struct ieee80211_key_conf
+ * pointed to by the @key parameter to the set_key() function.
+ *
+ * The set_key() call for the %SET_KEY command should return 0 if
+ * the key is now in use, -%EOPNOTSUPP or -%ENOSPC if it couldn't be
+ * added; if you return 0 then hw_key_idx must be assigned to the
+ * hardware key index, you are free to use the full u8 range.
+ *
+ * Note that in the case that the @IEEE80211_HW_SW_CRYPTO_CONTROL flag is
+ * set, mac80211 will not automatically fall back to software crypto if
+ * enabling hardware crypto failed. The set_key() call may also return the
+ * value 1 to permit this specific key/algorithm to be done in software.
+ *
+ * When the cmd is %DISABLE_KEY then it must succeed.
+ *
+ * Note that it is permissible to not decrypt a frame even if a key
+ * for it has been uploaded to hardware, the stack will not make any
+ * decision based on whether a key has been uploaded or not but rather
+ * based on the receive flags.
+ *
+ * The &struct ieee80211_key_conf structure pointed to by the @key
+ * parameter is guaranteed to be valid until another call to set_key()
+ * removes it, but it can only be used as a cookie to differentiate
+ * keys.
+ *
+ * In TKIP some HW need to be provided a phase 1 key, for RX decryption

+
+/**
+ * DOC: Powersave support
+ *
+ * mac80211 has support for various powersave implementations.
+ *
+ * First, it can support hardware that handles all powersaving by itself,
+ * such hardware should simply set the %IEEE80211_HW_SUPPORTS_PS hardware
+ * flag. In that case, it will be told about the desired powersave mode
+ * with the %IEEE80211_CONF_PS flag depending on the association status.
+ * The hardware must take care of sending nullfunc frames when necessary,
+ * i.e. when entering and leaving powersave mode. The hardware is required
+ * to look at the AID in beacons and signal to the AP that it woke up when
+ * it finds traffic directed to it.
+ *
+ * %IEEE80211_CONF_PS flag enabled means that the powersave mode defined in
+ * IEEE 802.11-2007 section 11.2 is enabled. This is not to be confused
+ * with hardware wakeup and sleep states. Driver is responsible for waking
+ * up the hardware before issuing commands to the hardware and putting it
+ * back to sleep at appropriate times.
+ *
+ * When PS is enabled, hardware needs to wakeup for beacons and receive the
+ * buffered multicast/broadcast frames after the beacon. Also it must be
+ * possible to send frames and receive the acknowledment frame.
+ *
+ * Other hardware designs cannot send nullfunc frames by themselves and also
+ * need software support for parsing the TIM bitmap. This is also supported
+ * by mac80211 by combining the %IEEE80211_HW_SUPPORTS_PS and
+ * %IEEE80211_HW_PS_NULLFUNC_STACK flags. The hardware is of course still
+ * required to pass up beacons. The hardware is still required to handle
+ * waking up for multicast traffic; if it cannot the driver must handle that
+ * as best as it can, mac80211 is too slow to do that.
+ *
+ * Dynamic powersave is an extension to normal powersave in which the
+ * hardware stays awake for a user-specified period of time after sending a
+ * frame so that reply frames need not be buffered and therefore delayed to
+ * the next wakeup. It's compromise of getting good enough latency when
+ * there's data traffic and still saving significantly power in idle
+ * periods.
+ *
+ * Dynamic powersave is simply supported by mac80211 enabling and disabling
+ * PS based on traffic. Driver needs to only set %IEEE80211_HW_SUPPORTS_PS
+ * flag and mac80211 will handle everything automatically. Additionally,
+ * hardware having support for the dynamic PS feature may set the
+ * %IEEE80211_HW_SUPPORTS_DYNAMIC_PS flag to indicate that it can support
+ * dynamic PS mode itself. The driver needs to look at the
+ * @dynamic_ps_timeout hardware configuration value and use it that value
+ * whenever %IEEE80211_CONF_PS is set. In this case mac80211 will disable
+ * dynamic PS feature in stack and will just keep %IEEE80211_CONF_PS
+ * enabled whenever user has enabled powersave.
+ *
+ * Driver informs U-APSD client support by enabling
+ * %IEEE80211_VIF_SUPPORTS_UAPSD flag. The mode is configured through the
+ * uapsd parameter in conf_tx() operation. Hardware needs to send the QoS
+ * Nullfunc frames and stay awake until the service period has ended. To
+ * utilize U-APSD, dynamic powersave is disabled for voip AC and all frames
+ * from that AC are transmitted with powersave enabled.
+ *
+ * Note: U-APSD client mode is not yet supported with
+ * %IEEE80211_HW_PS_NULLFUNC_STACK.
+ */
+
+/**
+ * DOC: Beacon filter support
+ *
+ * Some hardware have beacon filter support to reduce host cpu wakeups
+ * which will reduce system power consumption. It usually works so that
+ * the firmware creates a checksum of the beacon but omits all constantly
+ * changing elements (TSF, TIM etc). Whenever the checksum changes the
+ * beacon is forwarded to the host, otherwise it will be just dropped. That
+ * way the host will only receive beacons where some relevant information
+ * (for example ERP protection or WMM settings) have changed.
+ *
+ * Beacon filter support is advertised with the %IEEE80211_VIF_BEACON_FILTER
+ * interface capability. The driver needs to enable beacon filter support
+ * whenever power save is enabled, that is %IEEE80211_CONF_PS is set. When
+ * power save is enabled, the stack will not check for beacon loss and the
+ * driver needs to notify about loss of beacons with ieee80211_beacon_loss().
+ *
+ * The time (or number of beacons missed) until the firmware notifies the
+ * driver of a beacon loss event (which in turn causes the driver to call
+ * ieee80211_beacon_loss()) should be configurable and will be controlled
+ * by mac80211 and the roaming algorithm in the future.
+ *
+ * Since there may be constantly changing information elements that nothing
+ * in the software stack cares about, we will, in the future, have mac80211
+ * tell the driver which information elements are interesting in the sense
+ * that we want to see changes in them. This will include
+ *  - a list of information element IDs
+ *  - a list of OUIs for the vendor information element
+ *
+ * Ideally, the hardware would filter out any beacons without changes in the
+ * requested elements, but if it cannot support that it may, at the expense
+ * of some efficiency, filter out only a subset. For example, if the device
+ * doesn't support checking for OUIs it should pass up all changes in all
+ * vendor information elements.
+ *
+ * Note that change, for the sake of simplification, also includes information
+ * elements appearing or disappearing from the beacon.
+ *
+ * Some hardware supports an "ignore list" instead, just make sure nothing
+ * that was requested is on the ignore list, and include commonly changing
+ * information element IDs in the ignore list, for example 11 (BSS load) and
+ * the various vendor-assigned IEs with unknown contents (128, 129, 133-136,
+ * 149, 150, 155, 156, 173, 176, 178, 179, 219); for forward compatibility
+ * it could also include some currently unused IDs.
+ *
+ *
+ * In addition to these capabilities, hardware should support notifying the
+ * host of changes in the beacon RSSI. This is relevant to implement roaming
+ * when no traffic is flowing (when traffic is flowing we see the RSSI of
+ * the received data packets). This can consist in notifying the host when
+ * the RSSI changes significantly or when it drops below or rises above
+ * configurable thresholds. In the future these thresholds will also be
+ * configured by mac80211 (which gets them from userspace) to implement
+ * them as the roaming algorithm requires.
+ *
+ * If the hardware cannot implement this, the driver should ask it to
+ * periodically pass beacon frames to the host so that software can do the
+ * signal strength threshold checking.

+ * having as few frames as possible percolate through the stack is
+ * desirable. Hence, the hardware should filter as much as possible.
+ *
+ * To achieve this, mac80211 uses filter flags (see below) to tell
+ * the driver's configure_filter() function which frames should be
+ * passed to mac80211 and which should be filtered out.
+ *
+ * Before configure_filter() is invoked, the prepare_multicast()
+ * callback is invoked with the parameters @mc_count and @mc_list
+ * for the combined multicast address list of all virtual interfaces.
+ * It's use is optional, and it returns a u64 that is passed to
+ * configure_filter(). Additionally, configure_filter() has the
+ * arguments @changed_flags telling which flags were changed and
+ * @total_flags with the new flag states.
+ *
+ * If your device has no multicast address filters your driver will
+ * need to check both the %FIF_ALLMULTI flag and the @mc_count
+ * parameter to see whether multicast frames should be accepted
+ * or dropped.
+ *
+ * All unsupported flags in @total_flags must be cleared.
+ * Hardware does not support a flag if it is incapable of _passing_
+ * the frame to the stack. Otherwise the driver must ignore
+ * the flag, but not clear it.
+ * You must _only_ clear the flag (announce no support for the
+ * flag to mac80211) if you are not able to pass the packet type
+ * to the stack (so the hardware always filters it).
+ * So for example, you should clear @FIF_CONTROL, if your hardware
+ * always filters control frames. If your hardware always passes
+ * control frames to the kernel and is incapable of filtering them,
+ * you do _not_ clear the @FIF_CONTROL flag.
+ * This rule applies to all other FIF flags as well.

+/**
+ * DOC: AP support for powersaving clients
+ *
+ * In order to implement AP and P2P GO modes, mac80211 has support for
+ * client powersaving, both "legacy" PS (PS-Poll/null data) and uAPSD.
+ * There currently is no support for sAPSD.
+ *
+ * There is one assumption that mac80211 makes, namely that a client
+ * will not poll with PS-Poll and trigger with uAPSD at the same time.
+ * Both are supported, and both can be used by the same client, but
+ * they can't be used concurrently by the same client. This simplifies
+ * the driver code.
+ *
+ * The first thing to keep in mind is that there is a flag for complete
+ * driver implementation: %IEEE80211_HW_AP_LINK_PS. If this flag is set,
+ * mac80211 expects the driver to handle most of the state machine for
+ * powersaving clients and will ignore the PM bit in incoming frames.
+ * Drivers then use ieee80211_sta_ps_transition() to inform mac80211 of
+ * stations' powersave transitions. In this mode, mac80211 also doesn't
+ * handle PS-Poll/uAPSD.
+ *
+ * In the mode without %IEEE80211_HW_AP_LINK_PS, mac80211 will check the
+ * PM bit in incoming frames for client powersave transitions. When a
+ * station goes to sleep, we will stop transmitting to it. There is,
+ * however, a race condition: a station might go to sleep while there is
+ * data buffered on hardware queues. If the device has support for this
+ * it will reject frames, and the driver should give the frames back to
+ * mac80211 with the %IEEE80211_TX_STAT_TX_FILTERED flag set which will
+ * cause mac80211 to retry the frame when the station wakes up. The
+ * driver is also notified of powersave transitions by calling its
+ * @sta_notify callback.
+ *
+ * When the station is asleep, it has three choices: it can wake up,
+ * it can PS-Poll, or it can possibly start a uAPSD service period.
+ * Waking up is implemented by simply transmitting all buffered (and
+ * filtered) frames to the station. This is the easiest case. When
+ * the station sends a PS-Poll or a uAPSD trigger frame, mac80211
+ * will inform the driver of this with the @allow_buffered_frames
+ * callback; this callback is optional. mac80211 will then transmit
+ * the frames as usual and set the %IEEE80211_TX_CTL_NO_PS_BUFFER
+ * on each frame. The last frame in the service period (or the only
+ * response to a PS-Poll) also has %IEEE80211_TX_STATUS_EOSP set to
+ * indicate that it ends the service period; as this frame must have
+ * TX status report it also sets %IEEE80211_TX_CTL_REQ_TX_STATUS.
+ * When TX status is reported for this frame, the service period is
+ * marked has having ended and a new one can be started by the peer.
+ *
+ * Additionally, non-bufferable MMPDUs can also be transmitted by
+ * mac80211 with the %IEEE80211_TX_CTL_NO_PS_BUFFER set in them.
+ *
+ * Another race condition can happen on some devices like iwlwifi
+ * when there are frames queued for the station and it wakes up
+ * or polls; the frames that are already queued could end up being
+ * transmitted first instead, causing reordering and/or wrong
+ * processing of the EOSP. The cause is that allowing frames to be
+ * transmitted to a certain station is out-of-band communication to
+ * the device. To allow this problem to be solved, the driver can
+ * call ieee80211_sta_block_awake() if frames are buffered when it
+ * is notified that the station went to sleep. When all these frames
+ * have been filtered (see above), it must call the function again
+ * to indicate that the station is no longer blocked.
+ *
+ * If the driver buffers frames in the driver for aggregation in any
+ * way, it must use the ieee80211_sta_set_buffered() call when it is
+ * notified of the station going to sleep to inform mac80211 of any
+ * TIDs that have frames buffered. Note that when a station wakes up
+ * this information is reset (hence the requirement to call it when
+ * informed of the station going to sleep). Then, when a service
+ * period starts for any reason, @release_buffered_frames is called
+ * with the number of frames to be released and which TIDs they are
+ * to come from. In this case, the driver is responsible for setting
+ * the EOSP (for uAPSD) and MORE_DATA bits in the released frames,
+ * to help the @more_data parameter is passed to tell the driver if
+ * there is more data on other TIDs -- the TIDs to release frames
+ * from are ignored since mac80211 doesn't know how many frames the
+ * buffers for those TIDs contain.
+ *
+ * If the driver also implement GO mode, where absence periods may
+ * shorten service periods (or abort PS-Poll responses), it must
+ * filter those response frames except in the case of frames that
+ * are buffered in the driver -- those must remain buffered to avoid
+ * reordering. Because it is possible that no frames are released
+ * in this case, the driver must call ieee80211_sta_eosp()
+ * to indicate to mac80211 that the service period ended anyway.
+ *
+ * Finally, if frames from multiple TIDs are released from mac80211
+ * but the driver might reorder them, it must clear & set the flags
+ * appropriately (only the last frame may have %IEEE80211_TX_STATUS_EOSP)
+ * and also take care of the EOSP and MORE_DATA bits in the frame.
+ * The driver may also use ieee80211_sta_eosp() in this case.
+ *
+ * Note that if the driver ever buffers frames other than QoS-data
+ * frames, it must take care to never send a non-QoS-data frame as
+ * the last frame in a service period, adding a QoS-nulldata frame
+ * after a non-QoS-data frame if needed.

+/**
+ * DOC: HW queue control
+ *
+ * Before HW queue control was introduced, mac80211 only had a single static
+ * assignment of per-interface AC software queues to hardware queues. This
+ * was problematic for a few reasons:
+ * 1) off-channel transmissions might get stuck behind other frames
+ * 2) multiple virtual interfaces couldn't be handled correctly
+ * 3) after-DTIM frames could get stuck behind other frames
+ *
+ * To solve this, hardware typically uses multiple different queues for all
+ * the different usages, and this needs to be propagated into mac80211 so it
+ * won't have the same problem with the software queues.
+ *
+ * Therefore, mac80211 now offers the %IEEE80211_HW_QUEUE_CONTROL capability
+ * flag that tells it that the driver implements its own queue control. To do
+ * so, the driver will set up the various queues in each &struct ieee80211_vif
+ * and the offchannel queue in &struct ieee80211_hw. In response, mac80211 will
+ * use those queue IDs in the hw_queue field of &struct ieee80211_tx_info and
+ * if necessary will queue the frame on the right software queue that mirrors
+ * the hardware queue.
+ * Additionally, the driver has to then use these HW queue IDs for the queue
+ * management functions (ieee80211_stop_queue() et al.)
+ *
+ * The driver is free to set up the queue mappings as needed, multiple virtual
+ * interfaces may map to the same hardware queues if needed. The setup has to
+ * happen during add_interface or change_interface callbacks. For example, a
+ * driver supporting station+station and station+AP modes might decide to have
+ * 10 hardware queues to handle different scenarios:
+ *
+ * 4 AC HW queues for 1st vif: 0, 1, 2, 3
+ * 4 AC HW queues for 2nd vif: 4, 5, 6, 7
+ * after-DTIM queue for AP:   8
+ * off-channel queue:         9
+ *
+ * It would then set up the hardware like this:
+ *   hw.offchannel_tx_hw_queue = 9
+ *
+ * and the first virtual interface that is added as follows:
+ *   vif.hw_queue[IEEE80211_AC_VO] = 0
+ *   vif.hw_queue[IEEE80211_AC_VI] = 1
+ *   vif.hw_queue[IEEE80211_AC_BE] = 2
+ *   vif.hw_queue[IEEE80211_AC_BK] = 3
+ *   vif.cab_queue = 8 // if AP mode, otherwise %IEEE80211_INVAL_HW_QUEUE
+ * and the second virtual interface with 4-7.
+ *
+ * If queue 6 gets full, for example, mac80211 would only stop the second
+ * virtual interface's BE queue since virtual interface queues are per AC.
+ *
+ * Note that the vif.cab_queue value should be set to %IEEE80211_INVAL_HW_QUEUE
+ * whenever the queue is not used (i.e. the interface is not in AP mode) if the
+ * queue could potentially be shared since mac80211 will look at cab_queue when
+ * a queue is stopped/woken even if the interface is not in AP mode.

+ * struct ieee80211_ops - callbacks from mac80211 to the driver
+ *
+ * This structure contains various callbacks that the driver may
+ * handle or, in some cases, must handle, for example to configure
+ * the hardware to a new channel or to transmit a frame.
+ *
+ * @tx: Handler that 802.11 module calls for each transmitted frame.
+ *	skb contains the buffer starting from the IEEE 802.11 header.
+ *	The low-level driver should send the frame out based on
+ *	configuration in the TX control data. This handler should,
+ *	preferably, never fail and stop queues appropriately.
+ *	Must be atomic.
+ *
+ * @start: Called before the first netdevice attached to the hardware
+ *	is enabled. This should turn on the hardware and must turn on
+ *	frame reception (for possibly enabled monitor interfaces.)
+ *	Returns negative error codes, these may be seen in userspace,
+ *	or zero.
+ *	When the device is started it should not have a MAC address
+ *	to avoid acknowledging frames before a non-monitor device
+ *	is added.
+ *	Must be implemented and can sleep.
+ *
+ * @stop: Called after last netdevice attached to the hardware
+ *	is disabled. This should turn off the hardware (at least
+ *	it must turn off frame reception.)
+ *	May be called right after add_interface if that rejects
+ *	an interface. If you added any work onto the mac80211 workqueue
+ *	you should ensure to cancel it on this callback.
+ *	Must be implemented and can sleep.
+ *
+ * @suspend: Suspend the device; mac80211 itself will quiesce before and
+ *	stop transmitting and doing any other configuration, and then
+ *	ask the device to suspend. This is only invoked when WoWLAN is
+ *	configured, otherwise the device is deconfigured completely and
+ *	reconfigured at resume time.
+ *	The driver may also impose special conditions under which it
+ *	wants to use the "normal" suspend (deconfigure), say if it only
+ *	supports WoWLAN when the device is associated. In this case, it
+ *	must return 1 from this function.
+ *
+ * @resume: If WoWLAN was configured, this indicates that mac80211 is
+ *	now resuming its operation, after this the device must be fully
+ *	functional again. If this returns an error, the only way out is
+ *	to also unregister the device. If it returns 1, then mac80211
+ *	will also go through the regular complete restart on resume.
+ *
+ * @set_wakeup: Enable or disable wakeup when WoWLAN configuration is
+ *	modified. The reason is that device_set_wakeup_enable() is
+ *	supposed to be called when the configuration changes, not only
+ *	in suspend().
+ *
+ * @add_interface: Called when a netdevice attached to the hardware is
+ *	enabled. Because it is not called for monitor mode devices, @start
+ *	and @stop must be implemented.
+ *	The driver should perform any initialization it needs before
+ *	the device can be enabled. The initial configuration for the
+ *	interface is given in the conf parameter.
+ *	The callback may refuse to add an interface by returning a
+ *	negative error code (which will be seen in userspace.)
+ *	Must be implemented and can sleep.
+ *
+ * @change_interface: Called when a netdevice changes type. This callback
+ *	is optional, but only if it is supported can interface types be
+ *	switched while the interface is UP. The callback may sleep.
+ *	Note that while an interface is being switched, it will not be
+ *	found by the interface iteration callbacks.
+ *
+ * @remove_interface: Notifies a driver that an interface is going down.
+ *	The @stop callback is called after this if it is the last interface
+ *	and no monitor interfaces are present.
+ *	When all interfaces are removed, the MAC address in the hardware
+ *	must be cleared so the device no longer acknowledges packets,
+ *	the mac_addr member of the conf structure is, however, set to the
+ *	MAC address of the device going away.
+ *	Hence, this callback must be implemented. It can sleep.
+ *
+ * @config: Handler for configuration requests. IEEE 802.11 code calls this
+ *	function to change hardware configuration, e.g., channel.
+ *	This function should never fail but returns a negative error code
+ *	if it does. The callback can sleep.
+ *
+ * @bss_info_changed: Handler for configuration requests related to BSS
+ *	parameters that may vary during BSS's lifespan, and may affect low
+ *	level driver (e.g. assoc/disassoc status, erp parameters).
+ *	This function should not be used if no BSS has been set, unless
+ *	for association indication. The @changed parameter indicates which
+ *	of the bss parameters has changed when a call is made. The callback
+ *	can sleep.
+ *
+ * @prepare_multicast: Prepare for multicast filter configuration.
+ *	This callback is optional, and its return value is passed
+ *	to configure_filter(). This callback must be atomic.
+ *
+ * @configure_filter: Configure the device's RX filter.
+ *	See the section "Frame filtering" for more information.
+ *	This callback must be implemented and can sleep.
+ *
+ * @set_tim: Set TIM bit. mac80211 calls this function when a TIM bit
+ * 	must be set or cleared for a given STA. Must be atomic.
+ *
+ * @set_key: See the section "Hardware crypto acceleration"
+ *	This callback is only called between add_interface and
+ *	remove_interface calls, i.e. while the given virtual interface
+ *	is enabled.
+ *	Returns a negative error code if the key can't be added.
+ *	The callback can sleep.
+ *
+ * @update_tkip_key: See the section "Hardware crypto acceleration"
+ * 	This callback will be called in the context of Rx. Called for drivers
+ * 	which set IEEE80211_KEY_FLAG_TKIP_REQ_RX_P1_KEY.
+ *	The callback must be atomic.
+ *
+ * @set_rekey_data: If the device supports GTK rekeying, for example while the
+ *	host is suspended, it can assign this callback to retrieve the data
+ *	necessary to do GTK rekeying, this is the KEK, KCK and replay counter.
+ *	After rekeying was done it should (for example during resume) notify
+ *	userspace of the new replay counter using ieee80211_gtk_rekey_notify().
+ *
+ * @set_default_unicast_key: Set the default (unicast) key index, useful for
+ *	WEP when the device sends data packets autonomously, e.g. for ARP
+ *	offloading. The index can be 0-3, or -1 for unsetting it.
+ *
+ * @hw_scan: Ask the hardware to service the scan request, no need to start
+ *	the scan state machine in stack. The scan must honour the channel
+ *	configuration done by the regulatory agent in the wiphy's
+ *	registered bands. The hardware (or the driver) needs to make sure
+ *	that power save is disabled.
+ *	The @req ie/ie_len members are rewritten by mac80211 to contain the
+ *	entire IEs after the SSID, so that drivers need not look at these
+ *	at all but just send them after the SSID -- mac80211 includes the
+ *	(extended) supported rates and HT information (where applicable).
+ *	When the scan finishes, ieee80211_scan_completed() must be called;
+ *	note that it also must be called when the scan cannot finish due to
+ *	any error unless this callback returned a negative error code.
+ *	The callback can sleep.
+ *
+ * @cancel_hw_scan: Ask the low-level tp cancel the active hw scan.
+ *	The driver should ask the hardware to cancel the scan (if possible),
+ *	but the scan will be completed only after the driver will call
+ *	ieee80211_scan_completed().
+ *	This callback is needed for wowlan, to prevent enqueueing a new
+ *	scan_work after the low-level driver was already suspended.
+ *	The callback can sleep.
+ *
+ * @sched_scan_start: Ask the hardware to start scanning repeatedly at
+ *	specific intervals.  The driver must call the
+ *	ieee80211_sched_scan_results() function whenever it finds results.
+ *	This process will continue until sched_scan_stop is called.
+ *
+ * @sched_scan_stop: Tell the hardware to stop an ongoing scheduled scan.
+ *	In this case, ieee80211_sched_scan_stopped() must not be called.
+ *
+ * @sw_scan_start: Notifier function that is called just before a software scan
+ *	is started. Can be NULL, if the driver doesn't need this notification.
+ *	The mac_addr parameter allows supporting NL80211_SCAN_FLAG_RANDOM_ADDR,
+ *	the driver may set the NL80211_FEATURE_SCAN_RANDOM_MAC_ADDR flag if it
+ *	can use this parameter. The callback can sleep.
+ *
+ * @sw_scan_complete: Notifier function that is called just after a
+ *	software scan finished. Can be NULL, if the driver doesn't need
+ *	this notification.
+ *	The callback can sleep.
+ *
+ * @get_stats: Return low-level statistics.
+ * 	Returns zero if statistics are available.
+ *	The callback can sleep.
+ *
+ * @get_tkip_seq: If your device implements TKIP encryption in hardware this
+ *	callback should be provided to read the TKIP transmit IVs (both IV32
+ *	and IV16) for the given key from hardware.
+ *	The callback must be atomic.
+ *
+ * @set_frag_threshold: Configuration of fragmentation threshold. Assign this
+ *	if the device does fragmentation by itself; if this callback is
+ *	implemented then the stack will not do fragmentation.
+ *	The callback can sleep.
+ *
+ * @set_rts_threshold: Configuration of RTS threshold (if device needs it)
+ *	The callback can sleep.
+ *
+ * @sta_add: Notifies low level driver about addition of an associated station,
+ *	AP, IBSS/WDS/mesh peer etc. This callback can sleep.
+ *
+ * @sta_remove: Notifies low level driver about removal of an associated
+ *	station, AP, IBSS/WDS/mesh peer etc. Note that after the callback
+ *	returns it isn't safe to use the pointer, not even RCU protected;
+ *	no RCU grace period is guaranteed between returning here and freeing
+ *	the station. See @sta_pre_rcu_remove if needed.
+ *	This callback can sleep.
+ *
+ * @sta_add_debugfs: Drivers can use this callback to add debugfs files
+ *	when a station is added to mac80211's station list. This callback
+ *	and @sta_remove_debugfs should be within a CONFIG_MAC80211_DEBUGFS
+ *	conditional. This callback can sleep.
+ *
+ * @sta_remove_debugfs: Remove the debugfs files which were added using
+ *	@sta_add_debugfs. This callback can sleep.
+ *
+ * @sta_notify: Notifies low level driver about power state transition of an
+ *	associated station, AP,  IBSS/WDS/mesh peer etc. For a VIF operating
+ *	in AP mode, this callback will not be called when the flag
+ *	%IEEE80211_HW_AP_LINK_PS is set. Must be atomic.
+ *
+ * @sta_state: Notifies low level driver about state transition of a
+ *	station (which can be the AP, a client, IBSS/WDS/mesh peer etc.)
+ *	This callback is mutually exclusive with @sta_add/@sta_remove.
+ *	It must not fail for down transitions but may fail for transitions
+ *	up the list of states. Also note that after the callback returns it
+ *	isn't safe to use the pointer, not even RCU protected - no RCU grace
+ *	period is guaranteed between returning here and freeing the station.
+ *	See @sta_pre_rcu_remove if needed.
+ *	The callback can sleep.
+ *
+ * @sta_pre_rcu_remove: Notify driver about station removal before RCU
+ *	synchronisation. This is useful if a driver needs to have station
+ *	pointers protected using RCU, it can then use this call to clear
+ *	the pointers instead of waiting for an RCU grace period to elapse
+ *	in @sta_state.
+ *	The callback can sleep.
+ *
+ * @sta_rc_update: Notifies the driver of changes to the bitrates that can be
+ *	used to transmit to the station. The changes are advertised with bits
+ *	from &enum ieee80211_rate_control_changed and the values are reflected
+ *	in the station data. This callback should only be used when the driver
+ *	uses hardware rate control (%IEEE80211_HW_HAS_RATE_CONTROL) since
+ *	otherwise the rate control algorithm is notified directly.
+ *	Must be atomic.
+ * @sta_rate_tbl_update: Notifies the driver that the rate table changed. This
+ *	is only used if the configured rate control algorithm actually uses
+ *	the new rate table API, and is therefore optional. Must be atomic.
+ *
+ * @sta_statistics: Get statistics for this station. For example with beacon
+ *	filtering, the statistics kept by mac80211 might not be accurate, so
+ *	let the driver pre-fill the statistics. The driver can fill most of
+ *	the values (indicating which by setting the filled bitmap), but not
+ *	all of them make sense - see the source for which ones are possible.
+ *	Statistics that the driver doesn't fill will be filled by mac80211.
+ *	The callback can sleep.
+ *
+ * @conf_tx: Configure TX queue parameters (EDCF (aifs, cw_min, cw_max),
+ *	bursting) for a hardware TX queue.
+ *	Returns a negative error code on failure.
+ *	The callback can sleep.
+ *
+ * @get_tsf: Get the current TSF timer value from firmware/hardware. Currently,
+ *	this is only used for IBSS mode BSSID merging and debugging. Is not a
+ *	required function.
+ *	The callback can sleep.
+ *
+ * @set_tsf: Set the TSF timer to the specified value in the firmware/hardware.
+ *	Currently, this is only used for IBSS mode debugging. Is not a
+ *	required function.
+ *	The callback can sleep.
+ *
+ * @reset_tsf: Reset the TSF timer and allow firmware/hardware to synchronize
+ *	with other STAs in the IBSS. This is only used in IBSS mode. This
+ *	function is optional if the firmware/hardware takes full care of
+ *	TSF synchronization.
+ *	The callback can sleep.
+ *
+ * @tx_last_beacon: Determine whether the last IBSS beacon was sent by us.
+ *	This is needed only for IBSS mode and the result of this function is
+ *	used to determine whether to reply to Probe Requests.
+ *	Returns non-zero if this device sent the last beacon.
+ *	The callback can sleep.
+ *
+ * @ampdu_action: Perform a certain A-MPDU action
+ * 	The RA/TID combination determines the destination and TID we want
+ * 	the ampdu action to be performed for. The action is defined through
+ * 	ieee80211_ampdu_mlme_action. Starting sequence number (@ssn)
+ * 	is the first frame we expect to perform the action on. Notice
+ * 	that TX/RX_STOP can pass NULL for this parameter.
+ *	The @buf_size parameter is only valid when the action is set to
+ *	%IEEE80211_AMPDU_TX_OPERATIONAL and indicates the peer's reorder
+ *	buffer size (number of subframes) for this session -- the driver
+ *	may neither send aggregates containing more subframes than this
+ *	nor send aggregates in a way that lost frames would exceed the
+ *	buffer size. If just limiting the aggregate size, this would be
+ *	possible with a buf_size of 8:
+ *	 - TX: 1.....7
+ *	 - RX:  2....7 (lost frame #1)
+ *	 - TX:        8..1...
+ *	which is invalid since #1 was now re-transmitted well past the
+ *	buffer size of 8. Correct ways to retransmit #1 would be:
+ *	 - TX:       1 or 18 or 81
+ *	Even "189" would be wrong since 1 could be lost again.
+ *
+ *	Returns a negative error code on failure.
+ *	The callback can sleep.
+ *
+ * @get_survey: Return per-channel survey information
+ *
+ * @rfkill_poll: Poll rfkill hardware state. If you need this, you also
+ *	need to set wiphy->rfkill_poll to %true before registration,
+ *	and need to call wiphy_rfkill_set_hw_state() in the callback.
+ *	The callback can sleep.
+ *
+ * @set_coverage_class: Set slot time for given coverage class as specified
+ *	in IEEE 802.11-2007 section 17.3.8.6 and modify ACK timeout
+ *	accordingly; coverage class equals to -1 to enable ACK timeout
+ *	estimation algorithm (dynack). To disable dynack set valid value for
+ *	coverage class. This callback is not required and may sleep.
+ *
+ * @testmode_cmd: Implement a cfg80211 test mode command. The passed @vif may
+ *	be %NULL. The callback can sleep.
+ * @testmode_dump: Implement a cfg80211 test mode dump. The callback can sleep.
+ *
+ * @flush: Flush all pending frames from the hardware queue, making sure
+ *	that the hardware queues are empty. The @queues parameter is a bitmap
+ *	of queues to flush, which is useful if different virtual interfaces
+ *	use different hardware queues; it may also indicate all queues.
+ *	If the parameter @drop is set to %true, pending frames may be dropped.
+ *	Note that vif can be NULL.
+ *	The callback can sleep.
+ *
+ * @channel_switch: Drivers that need (or want) to offload the channel
+ *	switch operation for CSAs received from the AP may implement this
+ *	callback. They must then call ieee80211_chswitch_done() to indicate
+ *	completion of the channel switch.
+ *
+ * @set_antenna: Set antenna configuration (tx_ant, rx_ant) on the device.
+ *	Parameters are bitmaps of allowed antennas to use for TX/RX. Drivers may
+ *	reject TX/RX mask combinations they cannot support by returning -EINVAL
+ *	(also see nl80211.h @NL80211_ATTR_WIPHY_ANTENNA_TX).
+ *
+ * @get_antenna: Get current antenna configuration from device (tx_ant, rx_ant).
+ *
+ * @remain_on_channel: Starts an off-channel period on the given channel, must
+ *	call back to ieee80211_ready_on_channel() when on that channel. Note
+ *	that normal channel traffic is not stopped as this is intended for hw
+ *	offload. Frames to transmit on the off-channel channel are transmitted
+ *	normally except for the %IEEE80211_TX_CTL_TX_OFFCHAN flag. When the
+ *	duration (which will always be non-zero) expires, the driver must call
+ *	ieee80211_remain_on_channel_expired().
+ *	Note that this callback may be called while the device is in IDLE and
+ *	must be accepted in this case.
+ *	This callback may sleep.
+ * @cancel_remain_on_channel: Requests that an ongoing off-channel period is
+ *	aborted before it expires. This callback may sleep.
+ *
+ * @set_ringparam: Set tx and rx ring sizes.
+ *
+ * @get_ringparam: Get tx and rx ring current and maximum sizes.
+ *
+ * @tx_frames_pending: Check if there is any pending frame in the hardware
+ *	queues before entering power save.
+ *
+ * @set_bitrate_mask: Set a mask of rates to be used for rate control selection
+ *	when transmitting a frame. Currently only legacy rates are handled.
+ *	The callback can sleep.
+ * @event_callback: Notify driver about any event in mac80211. See
+ *	&enum ieee80211_event_type for the different types.
+ *	The callback can sleep.
+ *
+ * @release_buffered_frames: Release buffered frames according to the given
+ *	parameters. In the case where the driver buffers some frames for
+ *	sleeping stations mac80211 will use this callback to tell the driver
+ *	to release some frames, either for PS-poll or uAPSD.
+ *	Note that if the @more_data parameter is %false the driver must check
+ *	if there are more frames on the given TIDs, and if there are more than
+ *	the frames being released then it must still set the more-data bit in
+ *	the frame. If the @more_data parameter is %true, then of course the
+ *	more-data bit must always be set.
+ *	The @tids parameter tells the driver which TIDs to release frames
+ *	from, for PS-poll it will always have only a single bit set.
+ *	In the case this is used for a PS-poll initiated release, the
+ *	@num_frames parameter will always be 1 so code can be shared. In
+ *	this case the driver must also set %IEEE80211_TX_STATUS_EOSP flag
+ *	on the TX status (and must report TX status) so that the PS-poll
+ *	period is properly ended. This is used to avoid sending multiple
+ *	responses for a retried PS-poll frame.
+ *	In the case this is used for uAPSD, the @num_frames parameter may be
+ *	bigger than one, but the driver may send fewer frames (it must send
+ *	at least one, however). In this case it is also responsible for
+ *	setting the EOSP flag in the QoS header of the frames. Also, when the
+ *	service period ends, the driver must set %IEEE80211_TX_STATUS_EOSP
+ *	on the last frame in the SP. Alternatively, it may call the function
+ *	ieee80211_sta_eosp() to inform mac80211 of the end of the SP.
+ *	This callback must be atomic.
+ * @allow_buffered_frames: Prepare device to allow the given number of frames
+ *	to go out to the given station. The frames will be sent by mac80211
+ *	via the usual TX path after this call. The TX information for frames
+ *	released will also have the %IEEE80211_TX_CTL_NO_PS_BUFFER flag set
+ *	and the last one will also have %IEEE80211_TX_STATUS_EOSP set. In case
+ *	frames from multiple TIDs are released and the driver might reorder
+ *	them between the TIDs, it must set the %IEEE80211_TX_STATUS_EOSP flag
+ *	on the last frame and clear it on all others and also handle the EOSP
+ *	bit in the QoS header correctly. Alternatively, it can also call the
+ *	ieee80211_sta_eosp() function.
+ *	The @tids parameter is a bitmap and tells the driver which TIDs the
+ *	frames will be on; it will at most have two bits set.
+ *	This callback must be atomic.
+ *
+ * @get_et_sset_count:  Ethtool API to get string-set count.
+ *
+ * @get_et_stats:  Ethtool API to get a set of u64 stats.
+ *
+ * @get_et_strings:  Ethtool API to get a set of strings to describe stats
+ *	and perhaps other supported types of ethtool data-sets.
+ *
+ * @mgd_prepare_tx: Prepare for transmitting a management frame for association
+ *	before associated. In multi-channel scenarios, a virtual interface is
+ *	bound to a channel before it is associated, but as it isn't associated
+ *	yet it need not necessarily be given airtime, in particular since any
+ *	transmission to a P2P GO needs to be synchronized against the GO's
+ *	powersave state. mac80211 will call this function before transmitting a
+ *	management frame prior to having successfully associated to allow the
+ *	driver to give it channel time for the transmission, to get a response
+ *	and to be able to synchronize with the GO.
+ *	The callback will be called before each transmission and upon return
+ *	mac80211 will transmit the frame right away.
+ *	The callback is optional and can (should!) sleep.
+ *
+ * @mgd_protect_tdls_discover: Protect a TDLS discovery session. After sending
+ *	a TDLS discovery-request, we expect a reply to arrive on the AP's
+ *	channel. We must stay on the channel (no PSM, scan, etc.), since a TDLS
+ *	setup-response is a direct packet not buffered by the AP.
+ *	mac80211 will call this function just before the transmission of a TDLS
+ *	discovery-request. The recommended period of protection is at least
+ *	2 * (DTIM period).
+ *	The callback is optional and can sleep.
+ *
+ * @add_chanctx: Notifies device driver about new channel context creation.
+ * @remove_chanctx: Notifies device driver about channel context destruction.
+ * @change_chanctx: Notifies device driver about channel context changes that
+ *	may happen when combining different virtual interfaces on the same
+ *	channel context with different settings
+ * @assign_vif_chanctx: Notifies device driver about channel context being bound
+ *	to vif. Possible use is for hw queue remapping.
+ * @unassign_vif_chanctx: Notifies device driver about channel context being
+ *	unbound from vif.
+ * @switch_vif_chanctx: switch a number of vifs from one chanctx to
+ *	another, as specified in the list of
+ *	@ieee80211_vif_chanctx_switch passed to the driver, according
+ *	to the mode defined in &ieee80211_chanctx_switch_mode.
+ *
+ * @start_ap: Start operation on the AP interface, this is called after all the
+ *	information in bss_conf is set and beacon can be retrieved. A channel
+ *	context is bound before this is called. Note that if the driver uses
+ *	software scan or ROC, this (and @stop_ap) isn't called when the AP is
+ *	just "paused" for scanning/ROC, which is indicated by the beacon being
+ *	disabled/enabled via @bss_info_changed.
+ * @stop_ap: Stop operation on the AP interface.
+ *
+ * @reconfig_complete: Called after a call to ieee80211_restart_hw() and
+ *	during resume, when the reconfiguration has completed.
+ *	This can help the driver implement the reconfiguration step (and
+ *	indicate mac80211 is ready to receive frames).
+ *	This callback may sleep.
+ *
+ * @ipv6_addr_change: IPv6 address assignment on the given interface changed.
+ *	Currently, this is only called for managed or P2P client interfaces.
+ *	This callback is optional; it must not sleep.
+ *
+ * @channel_switch_beacon: Starts a channel switch to a new channel.
+ *	Beacons are modified to include CSA or ECSA IEs before calling this
+ *	function. The corresponding count fields in these IEs must be
+ *	decremented, and when they reach 1 the driver must call
+ *	ieee80211_csa_finish(). Drivers which use ieee80211_beacon_get()
+ *	get the csa counter decremented by mac80211, but must check if it is
+ *	1 using ieee80211_csa_is_complete() after the beacon has been
+ *	transmitted and then call ieee80211_csa_finish().
+ *	If the CSA count starts as zero or 1, this function will not be called,
+ *	since there won't be any time to beacon before the switch anyway.
+ * @pre_channel_switch: This is an optional callback that is called
+ *	before a channel switch procedure is started (ie. when a STA
+ *	gets a CSA or an userspace initiated channel-switch), allowing
+ *	the driver to prepare for the channel switch.
+ * @post_channel_switch: This is an optional callback that is called
+ *	after a channel switch procedure is completed, allowing the
+ *	driver to go back to a normal configuration.
+ *
+ * @join_ibss: Join an IBSS (on an IBSS interface); this is called after all
+ *	information in bss_conf is set up and the beacon can be retrieved. A
+ *	channel context is bound before this is called.
+ * @leave_ibss: Leave the IBSS again.
+ *
+ * @get_expected_throughput: extract the expected throughput towards the
+ *	specified station. The returned value is expressed in Kbps. It returns 0
+ *	if the RC algorithm does not have proper data to provide.
+ *
+ * @get_txpower: get current maximum tx power (in dBm) based on configuration
+ *	and hardware limits.
+ *
+ * @tdls_channel_switch: Start channel-switching with a TDLS peer. The driver
+ *	is responsible for continually initiating channel-switching operations
+ *	and returning to the base channel for communication with the AP. The
+ *	driver receives a channel-switch request template and the location of
+ *	the switch-timing IE within the template as part of the invocation.
+ *	The template is valid only within the call, and the driver can
+ *	optionally copy the skb for further re-use.
+ * @tdls_cancel_channel_switch: Stop channel-switching with a TDLS peer. Both
+ *	peers must be on the base channel when the call completes.
+ * @tdls_recv_channel_switch: a TDLS channel-switch related frame (request or
+ *	response) has been received from a remote peer. The driver gets
+ *	parameters parsed from the incoming frame and may use them to continue
+ *	an ongoing channel-switch operation. In addition, a channel-switch
+ *	response template is provided, together with the location of the
+ *	switch-timing IE within the template. The skb can only be used within
+ *	the function call.
+ *
+ * @wake_tx_queue: Called when new packets have been added to the queue.

+ * NetLabel - A management interface for maintaining network packet label

+ *
+ * Network protocols such as CIPSO and RIPSO require a label translation layer
+ * to convert the label on the packet into something meaningful on the host
+ * machine.  In the current Linux implementation these mapping tables live
+ * inside the kernel; NetLabel provides a mechanism for user space applications
+ * to manage these mapping tables.
+ *
+ * NetLabel makes use of the Generic NETLINK mechanism as a transport layer to
+ * send messages between kernel and user space.  The general format of a
+ * NetLabel message is shown below:
+ *
+ *  +-----------------+-------------------+--------- --- -- -
+ *  | struct nlmsghdr | struct genlmsghdr | payload
+ *  +-----------------+-------------------+--------- --- -- -
+ *
+ * The 'nlmsghdr' and 'genlmsghdr' structs should be dealt with like normal.
+ * The payload is dependent on the subsystem specified in the
+ * 'nlmsghdr->nlmsg_type' and should be defined below, supporting functions
+ * should be defined in the corresponding net/netlabel/netlabel_<subsys>.h|c
+ * file.  All of the fields in the NetLabel payload are NETLINK attributes, see
+ * the include/net/netlink.h file for more information on NETLINK attributes.

+ * @in_send_cmd: Initiator mode data exchange using RF technology and framing
+ *	previously set with in_configure_hw. The peer response is returned
+ *	through callback cb. If an io error occurs or the peer didn't reply
+ *	within the specified timeout (ms), the error code is passed back through
+ *	the resp pointer. This is an asynchronous function.
+ *
+ * Target mode: Only NFC-DEP protocol is supported in target mode.
+ * @tg_configure_hw: Hardware configuration for RF technology and communication
+ *	framing in target mode. This is a synchronous function.
+ * @tg_send_cmd: Target mode data exchange using RF technology and framing
+ *	previously set with tg_configure_hw. The peer next command is returned
+ *	through callback cb. If an io error occurs or the peer didn't reply
+ *	within the specified timeout (ms), the error code is passed back through
+ *	the resp pointer. This is an asynchronous function.
+ * @tg_listen: Put the device in listen mode waiting for data from the peer
+ *	device. This is an asynchronous function.
+ * @tg_listen_mdaa: If supported, put the device in automatic listen mode with
+ *	mode detection and automatic anti-collision. In this mode, the device
+ *	automatically detects the RF technology and executes the anti-collision
+ *	detection using the command responses specified in mdaa_params. The
+ *	mdaa_params structure contains SENS_RES, NFCID1, and SEL_RES for 106A RF
+ *	tech. NFCID2 and system code (sc) for 212F and 424F. The driver returns
+ *	the NFC-DEP ATR_REQ command through cb. The digital stack deducts the RF
+ *	tech by analyzing the SoD of the frame containing the ATR_REQ command.
+ *	This is an asynchronous function.
+ * @tg_listen_md: If supported, put the device in automatic listen mode with
+ *	mode detection but without automatic anti-collision. In this mode, the
+ *	device automatically detects the RF technology.  What the actual
+ *	RF technology is can be retrieved by calling @tg_get_rf_tech.
+ *	The digital stack will then perform the appropriate anti-collision
+ *	sequence.  This is an asynchronous function.
+ * @tg_get_rf_tech: Required when @tg_listen_md is supported, unused otherwise.
+ *	Return the RF Technology that was detected by the @tg_listen_md call.
+ *	This is a synchronous function.
+ *
+ * @switch_rf: Turns device radio on or off. The stack does not call explicitly
+ *	switch_rf to turn the radio on. A call to in|tg_configure_hw must turn
+ *	the device radio on.
+ * @abort_cmd: Discard the last sent command.
+ *
+ * Notes: Asynchronous functions have a timeout parameter. It is the driver
+ *	responsibility to call the digital stack back through the
+ *	nfc_digital_cmd_complete_t callback when no RF respsonse has been
+ *	received within the specified time (in milliseconds). In that case the
+ *	driver must set the resp sk_buff to ERR_PTR(-ETIMEDOUT).
+ *	Since the digital stack serializes commands to be sent, it's mandatory
+ *	for the driver to handle the timeout correctly. Otherwise the stack
+ *	would not be able to send new commands, waiting for the reply of the
+ *	current one.

+/*	Random Early Detection (RED) algorithm.
+	=======================================
+
+	Source: Sally Floyd and Van Jacobson, "Random Early Detection Gateways
+	for Congestion Avoidance", 1993, IEEE/ACM Transactions on Networking.
+
+	This file codes a "divisionless" version of RED algorithm
+	as written down in Fig.17 of the paper.
+
+	Short description.
+	------------------
+
+	When a new packet arrives we calculate the average queue length:
+
+	avg = (1-W)*avg + W*current_queue_len,
+
+	W is the filter time constant (chosen as 2^(-Wlog)), it controls
+	the inertia of the algorithm. To allow larger bursts, W should be
+	decreased.
+
+	if (avg > th_max) -> packet marked (dropped).
+	if (avg < th_min) -> packet passes.
+	if (th_min < avg < th_max) we calculate probability:
+
+	Pb = max_P * (avg - th_min)/(th_max-th_min)
+
+	and mark (drop) packet with this probability.
+	Pb changes from 0 (at avg==th_min) to max_P (avg==th_max).
+	max_P should be small (not 1), usually 0.01..0.02 is good value.
+
+	max_P is chosen as a number, so that max_P/(th_max-th_min)
+	is a negative power of two in order arithmetics to contain
+	only shifts.
+
+
+	Parameters, settable by user:
+	-----------------------------
+
+	qth_min		- bytes (should be < qth_max/2)
+	qth_max		- bytes (should be at least 2*qth_min and less limit)
+	Wlog	       	- bits (<32) log(1/W).
+	Plog	       	- bits (<32)
+
+	Plog is related to max_P by formula:
+
+	max_P = (qth_max-qth_min)/2^Plog;
+
+	F.e. if qth_max=128K and qth_min=32K, then Plog=22
+	corresponds to max_P=0.02
+
+	Scell_log
+	Stab
+
+	Lookup table for log((1-W)^(t/t_ave).
+
+
+	NOTES:
+
+	Upper bound on W.
+	-----------------
+
+	If you want to allow bursts of L packets of size S,
+	you should choose W:
+
+	L + 1 - th_min/S < (1-(1-W)^L)/W
+
+	th_min/S = 32         th_min/S = 4
+
+	log(W)	L
+	-1	33
+	-2	35
+	-3	39
+	-4	46
+	-5	57
+	-6	75
+	-7	101
+	-8	135
+	-9	190
+	etc.

+ * enum ieee80211_regulatory_flags - device regulatory flags
+ *
+ * @REGULATORY_CUSTOM_REG: tells us the driver for this device
+ *	has its own custom regulatory domain and cannot identify the
+ *	ISO / IEC 3166 alpha2 it belongs to. When this is enabled
+ *	we will disregard the first regulatory hint (when the
+ *	initiator is %REGDOM_SET_BY_CORE). Drivers that use
+ *	wiphy_apply_custom_regulatory() should have this flag set
+ *	or the regulatory core will set it for the wiphy.
+ *	If you use regulatory_hint() *after* using
+ *	wiphy_apply_custom_regulatory() the wireless core will
+ *	clear the REGULATORY_CUSTOM_REG for your wiphy as it would be
+ *	implied that the device somehow gained knowledge of its region.
+ * @REGULATORY_STRICT_REG: tells us that the wiphy for this device
+ *	has regulatory domain that it wishes to be considered as the
+ *	superset for regulatory rules. After this device gets its regulatory
+ *	domain programmed further regulatory hints shall only be considered
+ *	for this device to enhance regulatory compliance, forcing the
+ *	device to only possibly use subsets of the original regulatory
+ *	rules. For example if channel 13 and 14 are disabled by this
+ *	device's regulatory domain no user specified regulatory hint which
+ *	has these channels enabled would enable them for this wiphy,
+ *	the device's original regulatory domain will be trusted as the
+ *	base. You can program the superset of regulatory rules for this
+ *	wiphy with regulatory_hint() for cards programmed with an
+ *	ISO3166-alpha2 country code. wiphys that use regulatory_hint()
+ *	will have their wiphy->regd programmed once the regulatory
+ *	domain is set, and all other regulatory hints will be ignored
+ *	until their own regulatory domain gets programmed.
+ * @REGULATORY_DISABLE_BEACON_HINTS: enable this if your driver needs to
+ *	ensure that passive scan flags and beaconing flags may not be lifted by
+ *	cfg80211 due to regulatory beacon hints. For more information on beacon
+ *	hints read the documenation for regulatory_hint_found_beacon()
+ * @REGULATORY_COUNTRY_IE_FOLLOW_POWER:  for devices that have a preference
+ *	that even though they may have programmed their own custom power
+ *	setting prior to wiphy registration, they want to ensure their channel
+ *	power settings are updated for this connection with the power settings
+ *	derived from the regulatory domain. The regulatory domain used will be
+ *	based on the ISO3166-alpha2 from country IE provided through
+ *	regulatory_hint_country_ie()
+ * @REGULATORY_COUNTRY_IE_IGNORE: for devices that have a preference to ignore
+ * 	all country IE information processed by the regulatory core. This will
+ * 	override %REGULATORY_COUNTRY_IE_FOLLOW_POWER as all country IEs will
+ * 	be ignored.
+ * @REGULATORY_ENABLE_RELAX_NO_IR: for devices that wish to allow the
+ *      NO_IR relaxation, which enables transmissions on channels on which
+ *      otherwise initiating radiation is not allowed. This will enable the
+ *      relaxations enabled under the CFG80211_REG_RELAX_NO_IR configuration
+ *      option
+ * @REGULATORY_IGNORE_STALE_KICKOFF: the regulatory core will _not_ make sure
+ *	all interfaces on this wiphy reside on allowed channels. If this flag
+ *	is not set, upon a regdomain change, the interfaces are given a grace
+ *	period (currently 60 seconds) to disconnect or move to an allowed
+ *	channel. Interfaces on forbidden channels are forcibly disconnected.
+ *	Currently these types of interfaces are supported for enforcement:
+ *	NL80211_IFTYPE_ADHOC, NL80211_IFTYPE_STATION, NL80211_IFTYPE_AP,
+ *	NL80211_IFTYPE_AP_VLAN, NL80211_IFTYPE_MONITOR,
+ *	NL80211_IFTYPE_P2P_CLIENT, NL80211_IFTYPE_P2P_GO,
+ *	NL80211_IFTYPE_P2P_DEVICE. The flag will be set by default if a device
+ *	includes any modes unsupported for enforcement checking.
+ * @REGULATORY_WIPHY_SELF_MANAGED: for devices that employ wiphy-specific
+ *	regdom management. These devices will ignore all regdom changes not
+ *	originating from their own wiphy.
+ *	A self-managed wiphys only employs regulatory information obtained from
+ *	the FW and driver and does not use other cfg80211 sources like
+ *	beacon-hints, country-code IEs and hints from other devices on the same
+ *	system. Conversely, a self-managed wiphy does not share its regulatory
+ *	hints with other devices in the system. If a system contains several
+ *	devices, one or more of which are self-managed, there might be
+ *	contradictory regulatory settings between them. Usage of flag is
+ *	generally discouraged. Only use it if the FW/driver is incompatible
+ *	with non-locally originated hints.
+ *	This flag is incompatible with the flags: %REGULATORY_CUSTOM_REG,
+ *	%REGULATORY_STRICT_REG, %REGULATORY_COUNTRY_IE_FOLLOW_POWER,
+ *	%REGULATORY_COUNTRY_IE_IGNORE and %REGULATORY_DISABLE_BEACON_HINTS.
+ *	Mixing any of the above flags with this flag will result in a failure
+ *	to register the wiphy. This flag implies
+ *	%REGULATORY_DISABLE_BEACON_HINTS and %REGULATORY_COUNTRY_IE_IGNORE.

+ * Compressed packet format:
+ *
+ * The first octet contains the packet type (top 3 bits), TCP
+ * 'push' bit, and flags that indicate which of the 4 TCP sequence
+ * numbers have changed (bottom 5 bits).  The next octet is a
+ * conversation number that associates a saved IP/TCP header with
+ * the compressed packet.  The next two octets are the TCP checksum
+ * from the original datagram.  The next 0 to 15 octets are
+ * sequence number changes, one change per bit set in the header
+ * (there may be no changes and there are two special cases where
+ * the receiver implicitly knows what changed -- see below).
+ *
+ * There are 5 numbers which can change (they are always inserted
+ * in the following order): TCP urgent pointer, window,
+ * acknowledgment, sequence number and IP ID.  (The urgent pointer
+ * is different from the others in that its value is sent, not the
+ * change in value.)  Since typical use of SLIP links is biased
+ * toward small packets (see comments on MTU/MSS below), changes
+ * use a variable length coding with one octet for numbers in the
+ * range 1 - 255 and 3 octets (0, MSB, LSB) for numbers in the
+ * range 256 - 65535 or 0.  (If the change in sequence number or
+ * ack is more than 65535, an uncompressed packet is sent.)
+ */
+
+/*
+ * Packet types (must not conflict with IP protocol version)
+ *
+ * The top nibble of the first octet is the packet type.  There are
+ * three possible types: IP (not proto TCP or tcp with one of the
+ * control flags set); uncompressed TCP (a normal IP/TCP packet but
+ * with the 8-bit protocol field replaced by an 8-bit connection id --
+ * this type of packet syncs the sender & receiver); and compressed
+ * TCP (described above).
+ *
+ * LSB of 4-bit field is TCP "PUSH" bit (a worthless anachronism) and
+ * is logically part of the 4-bit "changes" field that follows.  Top
+ * three bits are actual packet type.  For backward compatibility
+ * and in the interest of conserving bits, numbers are chosen so the
+ * IP protocol version number (4) which normally appears in this nibble
+ * means "IP packet".

+ *
+ *
+ * The WiMAX stack provides an API for controlling and managing the
+ * system's WiMAX devices. This API affects the control plane; the
+ * data plane is accessed via the network stack (netdev).
+ *
+ * Parts of the WiMAX stack API and notifications are exported to
+ * user space via Generic Netlink. In user space, libwimax (part of
+ * the wimax-tools package) provides a shim layer for accessing those
+ * calls.
+ *
+ * The API is standarized for all WiMAX devices and different drivers
+ * implement the backend support for it. However, device-specific
+ * messaging pipes are provided that can be used to issue commands and
+ * receive notifications in free form.
+ *
+ * Currently the messaging pipes are the only means of control as it
+ * is not known (due to the lack of more devices in the market) what
+ * will be a good abstraction layer. Expect this to change as more
+ * devices show in the market. This API is designed to be growable in
+ * order to address this problem.
+ *
+ * USAGE
+ *
+ * Embed a `struct wimax_dev` at the beginning of the the device's
+ * private structure, initialize and register it. For details, see
+ * `struct wimax_dev`s documentation.
+ *
+ * Once this is done, wimax-tools's libwimaxll can be used to
+ * communicate with the driver from user space. You user space
+ * application does not have to forcibily use libwimaxll and can talk
+ * the generic netlink protocol directly if desired.
+ *
+ * Remember this is a very low level API that will to provide all of
+ * WiMAX features. Other daemons and services running in user space
+ * are the expected clients of it. They offer a higher level API that
+ * applications should use (an example of this is the Intel's WiMAX
+ * Network Service for the i2400m).
+ *
+ * DESIGN
+ *
+ * Although not set on final stone, this very basic interface is
+ * mostly completed. Remember this is meant to grow as new common
+ * operations are decided upon. New operations will be added to the
+ * interface, intent being on keeping backwards compatibility as much
+ * as possible.
+ *
+ * This layer implements a set of calls to control a WiMAX device,
+ * exposing a frontend to the rest of the kernel and user space (via
+ * generic netlink) and a backend implementation in the driver through
+ * function pointers.
+ *
+ * WiMAX devices have a state, and a kernel-only API allows the
+ * drivers to manipulate that state. State transitions are atomic, and
+ * only some of them are allowed (see `enum wimax_st`).
+ *
+ * Most API calls will set the state automatically; in most cases
+ * drivers have to only report state changes due to external
+ * conditions.
+ *
+ * All API operations are 'atomic', serialized through a mutex in the
+ * `struct wimax_dev`.
+ *
+ * EXPORTING TO USER SPACE THROUGH GENERIC NETLINK
+ *
+ * The API is exported to user space using generic netlink (other
+ * methods can be added as needed).
+ *
+ * There is a Generic Netlink Family named "WiMAX", where interfaces
+ * supporting the WiMAX interface receive commands and broadcast their
+ * signals over a multicast group named "msg".
+ *
+ * Mapping to the source/destination interface is done by an interface
+ * index attribute.
+ *
+ * For user-to-kernel traffic (commands) we use a function call
+ * marshalling mechanism, where a message X with attributes A, B, C
+ * sent from user space to kernel space means executing the WiMAX API
+ * call wimax_X(A, B, C), sending the results back as a message.
+ *
+ * Kernel-to-user (notifications or signals) communication is sent
+ * over multicast groups. This allows to have multiple applications
+ * monitoring them.
+ *
+ * Each command/signal gets assigned it's own attribute policy. This
+ * way the validator will verify that all the attributes in there are
+ * only the ones that should be for each command/signal. Thing of an
+ * attribute mapping to a type+argumentname for each command/signal.
+ *
+ * If we had a single policy for *all* commands/signals, after running
+ * the validator we'd have to check "does this attribute belong in
+ * here"?  for each one. It can be done manually, but it's just easier
+ * to have the validator do that job with multiple policies. As well,
+ * it makes it easier to later expand each command/signal signature
+ * without affecting others and keeping the namespace more or less
+ * sane. Not that it is too complicated, but it makes it even easier.
+ *
+ * No state information is maintained in the kernel for each user
+ * space connection (the connection is stateless).
+ *
+ * TESTING FOR THE INTERFACE AND VERSIONING
+ *
+ * If network interface X is a WiMAX device, there will be a Generic
+ * Netlink family named "WiMAX X" and the device will present a
+ * "wimax" directory in it's network sysfs directory
+ * (/sys/class/net/DEVICE/wimax) [used by HAL].
+ *
+ * The inexistence of any of these means the device does not support
+ * this WiMAX API.
+ *
+ * By querying the generic netlink controller, versioning information
+ * and the multicast groups available can be found. Applications using
+ * the interface can either rely on that or use the generic netlink
+ * controller to figure out which generic netlink commands/signals are
+ * supported.
+ *
+ * NOTE: this versioning is a last resort to avoid hard
+ *    incompatibilities. It is the intention of the design of this
+ *    stack not to introduce backward incompatible changes.
+ *
+ * The version code has to fit in one byte (restrictions imposed by
+ * generic netlink); we use `version / 10` for the major version and
+ * `version % 10` for the minor. This gives 9 minors for each major
+ * and 25 majors.
+ *
+ * The version change protocol is as follow:
+ *
+ * - Major versions: needs to be increased if an existing message/API
+ *   call is changed or removed. Doesn't need to be changed if a new
+ *   message is added.
+ *
+ * - Minor version: needs to be increased if new messages/API calls are
+ *   being added or some other consideration that doesn't impact the
+ *   user-kernel interface too much (like some kind of bug fix) and
+ *   that is kind of left up in the air to common sense.
+ *
+ * User space code should not try to work if the major version it was
+ * compiled for differs from what the kernel offers. As well, if the
+ * minor version of the kernel interface is lower than the one user
+ * space is expecting (the one it was compiled for), the kernel
+ * might be missing API calls; user space shall be ready to handle
+ * said condition. Use the generic netlink controller operations to
+ * find which ones are supported and which not.
+ *
+ * libwimaxll:wimaxll_open() takes care of checking versions.
+ *
+ * THE OPERATIONS:
+ *
+ * Each operation is defined in its on file (drivers/net/wimax/op-*.c)
+ * for clarity. The parts needed for an operation are:
+ *
+ *  - a function pointer in `struct wimax_dev`: optional, as the
+ *    operation might be implemented by the stack and not by the
+ *    driver.
+ *
+ *    All function pointers are named wimax_dev->op_*(), and drivers
+ *    must implement them except where noted otherwise.
+ *
+ *  - When exported to user space, a `struct nla_policy` to define the
+ *    attributes of the generic netlink command and a `struct genl_ops`
+ *    to define the operation.
+ *
+ * All the declarations for the operation codes (WIMAX_GNL_OP_<NAME>)
+ * and generic netlink attributes (WIMAX_GNL_<NAME>_*) are declared in
+ * include/linux/wimax.h; this file is intended to be cloned by user
+ * space to gain access to those declarations.
+ *
+ * A few caveats to remember:
+ *
+ *  - Need to define attribute numbers starting in 1; otherwise it
+ *    fails.
+ *
+ *  - the `struct genl_family` requires a maximum attribute id; when
+ *    defining the `struct nla_policy` for each message, it has to have
+ *    an array size of WIMAX_GNL_ATTR_MAX+1.
+ *
+ * The op_*() function pointers will not be called if the wimax_dev is
+ * in a state <= %WIMAX_ST_UNINITIALIZED. The exception is:
+ *
+ * - op_reset: can be called at any time after wimax_dev_add() has
+ *   been called.
+ *
+ * THE PIPE INTERFACE:
+ *
+ * This interface is kept intentionally simple. The driver can send
+ * and receive free-form messages to/from user space through a
+ * pipe. See drivers/net/wimax/op-msg.c for details.
+ *
+ * The kernel-to-user messages are sent with
+ * wimax_msg(). user-to-kernel messages are delivered via
+ * wimax_dev->op_msg_from_user().
+ *
+ * RFKILL:
+ *
+ * RFKILL support is built into the wimax_dev layer; the driver just
+ * needs to call wimax_report_rfkill_{hw,sw}() to inform of changes in
+ * the hardware or software RF kill switches. When the stack wants to
+ * turn the radio off, it will call wimax_dev->op_rfkill_sw_toggle(),
+ * which the driver implements.
+ *
+ * User space can set the software RF Kill switch by calling
+ * wimax_rfkill().
+ *
+ * The code for now only supports devices that don't require polling;
+ * If the device needs to be polled, create a self-rearming delayed
+ * work struct for polling or look into adding polled support to the
+ * WiMAX stack.
+ *
+ * When initializing the hardware (_probe), after calling
+ * wimax_dev_add(), query the device for it's RF Kill switches status
+ * and feed it back to the WiMAX stack using
+ * wimax_report_rfkill_{hw,sw}(). If any switch is missing, always
+ * report it as ON.
+ *
+ * NOTE: the wimax stack uses an inverted terminology to that of the
+ * RFKILL subsystem:
+ *
+ *  - ON: radio is ON, RFKILL is DISABLED or OFF.
+ *  - OFF: radio is OFF, RFKILL is ENABLED or ON.
+ *
+ * MISCELLANEOUS OPS:
+ *
+ * wimax_reset() can be used to reset the device to power on state; by
+ * default it issues a warm reset that maintains the same device
+ * node. If that is not possible, it falls back to a cold reset
+ * (device reconnect). The driver implements the backend to this
+ * through wimax_dev->op_reset().

+ *     return immediately.
+ *     NOTE: wimax_dev->mutex is NOT locked when this op is being
+ *     called; however, wimax_dev->mutex_reset IS locked to ensure
+ *     serialization of calls to wimax_reset().
+ *     See wimax_reset()'s documentation.
+ *
+ * @name: [fill] A way to identify this device. We need to register a
+ *     name with many subsystems (rfkill, workqueue creation, etc).
+ *     We can't use the network device name as that
+ *     might change and in some instances we don't know it yet (until
+ *     we don't call register_netdev()). So we generate an unique one
+ *     using the driver name and device bus id, place it here and use
+ *     it across the board. Recommended naming:
+ *     DRIVERNAME-BUSNAME:BUSID (dev->bus->name, dev->bus_id).
+ *
+ * @id_table_node: [private] link to the list of wimax devices kept by
+ *     id-table.c. Protected by it's own spinlock.
+ *
+ * @mutex: [private] Serializes all concurrent access and execution of
+ *     operations.
+ *
+ * @mutex_reset: [private] Serializes reset operations. Needs to be a
+ *     different mutex because as part of the reset operation, the
+ *     driver has to call back into the stack to do things such as
+ *     state change, that require wimax_dev->mutex.
+ *
+ * @state: [private] Current state of the WiMAX device.
+ *
+ * @rfkill: [private] integration into the RF-Kill infrastructure.
+ *
+ * @rf_sw: [private] State of the software radio switch (OFF/ON)
+ *
+ * @rf_hw: [private] State of the hardware radio switch (OFF/ON)
+ *
+ * @debugfs_dentry: [private] Used to hook up a debugfs entry. This
+ *     shows up in the debugfs root as wimax\:DEVICENAME.
+ *
+ * Description:
+ * This structure defines a common interface to access all WiMAX
+ * devices from different vendors and provides a common API as well as
+ * a free-form device-specific messaging channel.
+ *
+ * Usage:
+ *  1. Embed a &struct wimax_dev at *the beginning* the network
+ *     device structure so that netdev_priv() points to it.
+ *
+ *  2. memset() it to zero
+ *
+ *  3. Initialize with wimax_dev_init(). This will leave the WiMAX
+ *     device in the %__WIMAX_ST_NULL state.
+ *
+ *  4. Fill all the fields marked with [fill]; once called
+ *     wimax_dev_add(), those fields CANNOT be modified.
+ *
+ *  5. Call wimax_dev_add() *after* registering the network
+ *     device. This will leave the WiMAX device in the %WIMAX_ST_DOWN
+ *     state.
+ *     Protect the driver's net_device->open() against succeeding if
+ *     the wimax device state is lower than %WIMAX_ST_DOWN.
+ *
+ *  6. Select when the device is going to be turned on/initialized;
+ *     for example, it could be initialized on 'ifconfig up' (when the
+ *     netdev op 'open()' is called on the driver).
+ *
+ * When the device is initialized (at `ifconfig up` time, or right
+ * after calling wimax_dev_add() from _probe(), make sure the
+ * following steps are taken
+ *
+ *  a. Move the device to %WIMAX_ST_UNINITIALIZED. This is needed so
+ *     some API calls that shouldn't work until the device is ready
+ *     can be blocked.
+ *
+ *  b. Initialize the device. Make sure to turn the SW radio switch
+ *     off and move the device to state %WIMAX_ST_RADIO_OFF when
+ *     done. When just initialized, a device should be left in RADIO
+ *     OFF state until user space devices to turn it on.
+ *
+ *  c. Query the device for the state of the hardware rfkill switch
+ *     and call wimax_rfkill_report_hw() and wimax_rfkill_report_sw()
+ *     as needed. See below.
+ *
+ * wimax_dev_rm() undoes before unregistering the network device. Once
+ * wimax_dev_add() is called, the driver can get called on the
+ * wimax_dev->op_* function pointers
+ *
+ * CONCURRENCY:
+ *
+ * The stack provides a mutex for each device that will disallow API
+ * calls happening concurrently; thus, op calls into the driver
+ * through the wimax_dev->op*() function pointers will always be
+ * serialized and *never* concurrent.
+ *
+ * For locking, take wimax_dev->mutex is taken; (most) operations in
+ * the API have to check for wimax_dev_is_ready() to return 0 before
+ * continuing (this is done internally).
+ *
+ * REFERENCE COUNTING:
+ *
+ * The WiMAX device is reference counted by the associated network
+ * device. The only operation that can be used to reference the device
+ * is wimax_dev_get_by_genl_info(), and the reference it acquires has
+ * to be released with dev_put(wimax_dev->net_dev).
+ *
+ * RFKILL:
+ *
+ * At startup, both HW and SW radio switchess are assumed to be off.
+ *
+ * At initialization time [after calling wimax_dev_add()], have the
+ * driver query the device for the status of the software and hardware
+ * RF kill switches and call wimax_report_rfkill_hw() and
+ * wimax_rfkill_report_sw() to indicate their state. If any is
+ * missing, just call it to indicate it is ON (radio always on).
+ *
+ * Whenever the driver detects a change in the state of the RF kill
+ * switches, it should call wimax_report_rfkill_hw() or
+ * wimax_report_rfkill_sw() to report it to the stack.

+/* Organization of SPD aka "XFRM rules"
+   ------------------------------------
+
+   Basic objects:
+   - policy rule, struct xfrm_policy (=SPD entry)
+   - bundle of transformations, struct dst_entry == struct xfrm_dst (=SA bundle)
+   - instance of a transformer, struct xfrm_state (=SA)
+   - template to clone xfrm_state, struct xfrm_tmpl
+
+   SPD is plain linear list of xfrm_policy rules, ordered by priority.
+   (To be compatible with existing pfkeyv2 implementations,
+   many rules with priority of 0x7fffffff are allowed to exist and
+   such rules are ordered in an unpredictable way, thanks to bsd folks.)
+
+   Lookup is plain linear search until the first match with selector.
+
+   If "action" is "block", then we prohibit the flow, otherwise:
+   if "xfrms_nr" is zero, the flow passes untransformed. Otherwise,
+   policy entry has list of up to XFRM_MAX_DEPTH transformations,
+   described by templates xfrm_tmpl. Each template is resolved
+   to a complete xfrm_state (see below) and we pack bundle of transformations
+   to a dst_entry returned to requestor.
+
+   dst -. xfrm  .-> xfrm_state #1
+    |---. child .-> dst -. xfrm .-> xfrm_state #2
+                     |---. child .-> dst -. xfrm .-> xfrm_state #3
+                                      |---. child .-> NULL
+
+   Bundles are cached at xrfm_policy struct (field ->bundles).
+
+
+   Resolution of xrfm_tmpl
+   -----------------------
+   Template contains:
+   1. ->mode		Mode: transport or tunnel
+   2. ->id.proto	Protocol: AH/ESP/IPCOMP
+   3. ->id.daddr	Remote tunnel endpoint, ignored for transport mode.
+      Q: allow to resolve security gateway?
+   4. ->id.spi          If not zero, static SPI.
+   5. ->saddr		Local tunnel endpoint, ignored for transport mode.
+   6. ->algos		List of allowed algos. Plain bitmask now.
+      Q: ealgos, aalgos, calgos. What a mess...
+   7. ->share		Sharing mode.
+      Q: how to implement private sharing mode? To add struct sock* to
+      flow id?
+
+   Having this template we search through SAD searching for entries
+   with appropriate mode/proto/algo, permitted by selector.
+   If no appropriate entry found, it is requested from key manager.
+
+   PROBLEMS:
+   Q: How to find all the bundles referring to a physical path for
+      PMTU discovery? Seems, dst should contain list of all parents...
+      and enter to infinite locking hierarchy disaster.
+      No! It is easier, we will not search for them, let them find us.
+      We add genid to each dst plus pointer to genid of raw IP route,
+      pmtu disc will update pmtu on raw IP route and increase its genid.
+      dst_check() will see this for top level and trigger resyncing
+      metrics. Plus, it will be made via sk->sk_dst_cache. Solved.

+ *
+ *
+ *      The OPL-3 mode is switched on by writing 0x01, to the offset 5
+ *      of the right side.
+ *
+ *      Another special register at the right side is at offset 4. It contains
+ *      a bit mask defining which voices are used as 4 OP voices.
+ *
+ *      The percussive mode is implemented in the left side only.
+ *
+ *      With the above exceptions the both sides can be operated independently.
+ *      
+ *      A 4 OP voice can be created by setting the corresponding
+ *      bit at offset 4 of the right side.
+ *
+ *      For example setting the rightmost bit (0x01) changes the
+ *      first voice on the right side to the 4 OP mode. The fourth
+ *      voice is made inaccessible.
+ *
+ *      If a voice is set to the 2 OP mode, it works like 2 OP modes
+ *      of the original YM3812 (AdLib). In addition the voice can 
+ *      be connected the left, right or both stereo channels. It can
+ *      even be left unconnected. This works with 4 OP voices also.
+ *
+ *      The stereo connection bits are located in the FEEDBACK_CONNECTION
+ *      register of the voice (0xC0-0xC8). In 4 OP voices these bits are
+ *      in the second half of the voice.

+ *	detection, and a 0 upon reset completion, signifying no more error
+ *	exists. NOTE: Disabling hangcheck or reset via module parameter will

+ * Sets a CAN receive filter for the gateway job specified by the
+ * struct can_filter described in include/linux/can.h
+ *
+ * CGW_MOD_(AND|OR|XOR|SET) (length 17 bytes):
+ * Specifies a modification that's done to a received CAN frame before it is
+ * send out to the destination interface.
+ *
+ * <struct can_frame> data used as operator
+ * <u8> affected CAN frame elements
+ *
+ * CGW_LIM_HOPS (length 1 byte):
+ * Limit the number of hops of this specific rule. Usually the received CAN
+ * frame can be processed as much as 'max_hops' times (which is given at module
+ * load time of the can-gw module). This value is used to reduce the number of
+ * possible hops for this gateway rule to a value smaller then max_hops.
+ *
+ * CGW_CS_XOR (length 4 bytes):
+ * Set a simple XOR checksum starting with an initial value into
+ * data[result-idx] using data[start-idx] .. data[end-idx]
+ *
+ * The XOR checksum is calculated like this:
+ *
+ * xor = init_xor_val
+ *
+ * for (i = from_idx .. to_idx)
+ *      xor ^= can_frame.data[i]
+ *
+ * can_frame.data[ result_idx ] = xor
+ *
+ * CGW_CS_CRC8 (length 282 bytes):
+ * Set a CRC8 value into data[result-idx] using a given 256 byte CRC8 table,
+ * a given initial value and a defined input data[start-idx] .. data[end-idx].
+ * Finally the result value is XOR'ed with the final_xor_val.
+ *
+ * The CRC8 checksum is calculated like this:
+ *
+ * crc = init_crc_val
+ *
+ * for (i = from_idx .. to_idx)
+ *      crc = crctab[ crc ^ can_frame.data[i] ]
+ *
+ * can_frame.data[ result_idx ] = crc ^ final_xor_val
+ *
+ * The calculated CRC may contain additional source data elements that can be
+ * defined in the handling of 'checksum profiles' e.g. shown in AUTOSAR specs
+ * like http://www.autosar.org/download/R4.0/AUTOSAR_SWS_E2ELibrary.pdf
+ * E.g. the profile_data[] may contain additional u8 values (called DATA_IDs)
+ * that are used depending on counter values inside the CAN frame data[].
+ * So far only three profiles have been implemented for illustration.
+ *
+ * Remark: In general the attribute data is a linear buffer.
+ *         Beware of sending unpacked or aligned structs!

+/*******************************************************
+ * As of Linux 2.1.x, all Linux CD-ROM application programs will use this 
+ * (and only this) include file.  It is my hope to provide Linux with
+ * a uniform interface between software accessing CD-ROMs and the various 
+ * device drivers that actually talk to the drives.  There may still be
+ * 23 different kinds of strange CD-ROM drives, but at least there will 
+ * now be one, and only one, Linux CD-ROM interface.
+ *
+ * Additionally, as of Linux 2.1.x, all Linux application programs 
+ * should use the O_NONBLOCK option when opening a CD-ROM device 
+ * for subsequent ioctl commands.  This allows for neat system errors 
+ * like "No medium found" or "Wrong medium type" upon attempting to 
+ * mount or play an empty slot, mount an audio disc, or play a data disc.
+ * Generally, changing an application program to support O_NONBLOCK
+ * is as easy as the following:
+ *       -    drive = open("/dev/cdrom", O_RDONLY);
+ *       +    drive = open("/dev/cdrom", O_RDONLY | O_NONBLOCK);
+ * It is worth the small change.
+ *
+ *  Patches for many common CD programs (provided by David A. van Leeuwen)
+ *  can be found at:  ftp://ftp.gwdg.de/pub/linux/cdrom/drivers/cm206/
+ * 
+ *******************************************************/

+/* When a driver supports a certain function, but the cdrom drive we are 
+ * using doesn't, we will return the error EDRIVE_CANT_DO_THIS.  We will 
+ * borrow the "Operation not supported" error from the network folks to 
+ * accomplish this.  Maybe someday we will get a more targeted error code, 
+ * but this will do for now... */

+ * either return -EAGAIN from the dlm_lock call or will return 0 from
+ * dlm_lock and -EAGAIN in the lock status block when the AST is executed.
+ *
+ * DLM_LKF_CANCEL
+ *
+ * Used to cancel a pending lock request or conversion.  A converting lock is
+ * returned to its previously granted mode.
+ *
+ * DLM_LKF_CONVERT
+ *
+ * Indicates a lock conversion request.  For conversions the name and namelen
+ * are ignored and the lock ID in the LKSB is used to identify the lock.
+ *
+ * DLM_LKF_VALBLK
+ *
+ * Requests DLM to return the current contents of the lock value block in the
+ * lock status block.  When this flag is set in a lock conversion from PW or EX
+ * modes, DLM assigns the value specified in the lock status block to the lock
+ * value block of the lock resource.  The LVB is a DLM_LVB_LEN size array
+ * containing application-specific information.
+ *
+ * DLM_LKF_QUECVT
+ *
+ * Force a conversion request to be queued, even if it is compatible with
+ * the granted modes of other locks on the same resource.
+ *
+ * DLM_LKF_IVVALBLK
+ *
+ * Invalidate the lock value block.
+ *
+ * DLM_LKF_CONVDEADLK
+ *
+ * Allows the dlm to resolve conversion deadlocks internally by demoting the
+ * granted mode of a converting lock to NL.  The DLM_SBF_DEMOTED flag is
+ * returned for a conversion that's been effected by this.
+ *
+ * DLM_LKF_PERSISTENT
+ *
+ * Only relevant to locks originating in userspace.  A persistent lock will not
+ * be removed if the process holding the lock exits.
+ *
+ * DLM_LKF_NODLCKWT
+ *
+ * Do not cancel the lock if it gets into conversion deadlock.
+ * Exclude this lock from being monitored due to DLM_LSFL_TIMEWARN.
+ *
+ * DLM_LKF_NODLCKBLK
+ *
+ * net yet implemented
+ *
+ * DLM_LKF_EXPEDITE
+ *
+ * Used only with new requests for NL mode locks.  Tells the lock manager
+ * to grant the lock, ignoring other locks in convert and wait queues.
+ *
+ * DLM_LKF_NOQUEUEBAST
+ *
+ * Send blocking AST's before returning -EAGAIN to the caller.  It is only
+ * used along with the NOQUEUE flag.  Blocking AST's are not sent for failed
+ * NOQUEUE requests otherwise.
+ *
+ * DLM_LKF_HEADQUE
+ *
+ * Add a lock to the head of the convert or wait queue rather than the tail.
+ *
+ * DLM_LKF_NOORDER
+ *
+ * Disregard the standard grant order rules and grant a lock as soon as it
+ * is compatible with other granted locks.
+ *
+ * DLM_LKF_ORPHAN
+ *
+ * Acquire an orphan lock.
+ *
+ * DLM_LKF_ALTPR
+ *
+ * If the requested mode cannot be granted immediately, try to grant the lock
+ * in PR mode instead.  If this alternate mode is granted instead of the
+ * requested mode, DLM_SBF_ALTMODE is returned in the lksb.
+ *
+ * DLM_LKF_ALTCW
+ *
+ * The same as ALTPR, but the alternate mode is CW.
+ *
+ * DLM_LKF_FORCEUNLOCK
+ *
+ * Unlock the lock even if it is converting or waiting or has sublocks.
+ * Only really for use by the userland device.c code.

+ * DM_DEV_CREATE:
+ * Create a new device, neither the 'active' or 'inactive' table

+ * since it will be out-of-bounds.

+ * Remove a device, destroy any tables.
+ *
+ * DM_DEV_RENAME:
+ * Rename a device or set its uuid if none was previously supplied.

+ * DM_SUSPEND:
+ * This performs both suspend and resume, depending which flag is

+ * Suspend: This command will not return until all pending io to
+ * the device has completed.  Further io will be deferred until
+ * the device is resumed.
+ * Resume: It is no longer an error to issue this command on an
+ * unsuspended device.  If a table is present in the 'inactive'
+ * slot, it will be moved to the active slot, then the old table

+ * targets of the table in the 'active' slot, or a table change.
+ *
+ * DM_TABLE_LOAD:
+ * Load a table into the 'inactive' slot for the device.  The
+ * device does _not_ need to be suspended prior to this command.
+ *
+ * DM_TABLE_CLEAR:
+ * Destroy any table in the 'inactive' slot (ie. abort).
+ *
+ * DM_TABLE_DEPS:
+ * Return a set of device dependencies for the 'active' table.
+ *
+ * DM_TABLE_STATUS:
+ * Return the targets status for the 'active' table.
+ *
+ * DM_TARGET_MSG:
+ * Pass a message string to the target at a specific offset of a device.
+ *
+ * DM_DEV_SET_GEOMETRY:
+ * Set the geometry of a device by passing in a string in this format:
+ *
+ * "cylinders heads sectors_per_track start_sector"
+ *
+ * Beware that CHS geometry is nearly obsolete and only provided
+ * for compatibility with dm devices that can be booted by a PC

+/*
+ * The device-mapper userspace log module consists of a kernel component and
+ * a user-space component.  The kernel component implements the API defined
+ * in dm-dirty-log.h.  Its purpose is simply to pass the parameters and
+ * return values of those API functions between kernel and user-space.
+ *
+ * Below are defined the 'request_types' - DM_ULOG_CTR, DM_ULOG_DTR, etc.
+ * These request types represent the different functions in the device-mapper
+ * dirty log API.  Each of these is described in more detail below.
+ *
+ * The user-space program must listen for requests from the kernel (representing
+ * the various API functions) and process them.
+ *
+ * User-space begins by setting up the communication link (error checking
+ * removed for clarity):
+ *	fd = socket(PF_NETLINK, SOCK_DGRAM, NETLINK_CONNECTOR);
+ *	addr.nl_family = AF_NETLINK;
+ *	addr.nl_groups = CN_IDX_DM;
+ *	addr.nl_pid = 0;
+ *	r = bind(fd, (struct sockaddr *) &addr, sizeof(addr));
+ *	opt = addr.nl_groups;
+ *	setsockopt(fd, SOL_NETLINK, NETLINK_ADD_MEMBERSHIP, &opt, sizeof(opt));
+ *
+ * User-space will then wait to receive requests form the kernel, which it
+ * will process as described below.  The requests are received in the form,
+ * ((struct dm_ulog_request) + (additional data)).  Depending on the request
+ * type, there may or may not be 'additional data'.  In the descriptions below,
+ * you will see 'Payload-to-userspace' and 'Payload-to-kernel'.  The
+ * 'Payload-to-userspace' is what the kernel sends in 'additional data' as
+ * necessary parameters to complete the request.  The 'Payload-to-kernel' is
+ * the 'additional data' returned to the kernel that contains the necessary
+ * results of the request.  The 'data_size' field in the dm_ulog_request
+ * structure denotes the availability and amount of payload data.

+ *
+ * In version 1 of the ABI, no timestamp quadlet was inserted; instead, payload

+ * Context type %FW_CDEV_ISO_CONTEXT_TRANSMIT:
+ *
+ * @control.HEADER_LENGTH must be a multiple of 4.  It specifies the numbers of
+ * bytes in @header that will be prepended to the packet's payload.  These bytes
+ * are copied into the kernel and will not be accessed after the ioctl has
+ * returned.
+ *
+ * The @control.SY and TAG fields are copied to the iso packet header.  These
+ * fields are specified by IEEE 1394a and IEC 61883-1.
+ *
+ * The @control.SKIP flag specifies that no packet is to be sent in a frame.
+ * When using this, all other fields except @control.INTERRUPT must be zero.
+ *
+ * When a packet with the @control.INTERRUPT flag set has been completed, an
+ * &fw_cdev_event_iso_interrupt event will be sent.

+ *
+ * The @control.SY and TAG fields are ignored.
+ *
+ * If the @control.SYNC flag is set, the context drops all packets until a

+ * @control.PAYLOAD_LENGTH defines how many payload bytes can be received for
+ * one packet (in addition to payload quadlets that have been defined as headers
+ * and are stripped and returned in the &fw_cdev_event_iso_interrupt structure).
+ * If more bytes are received, the additional bytes are dropped.  If less bytes
+ * are received, the remaining bytes in this part of the payload buffer will not
+ * be written to, not even by the next packet.  I.e., packets received in
+ * consecutive frames will not necessarily be consecutive in memory.  If an
+ * entry has queued multiple packets, the PAYLOAD_LENGTH is divided equally
+ * among them.
+ *
+ * When a packet with the @control.INTERRUPT flag set has been completed, an

+ *
+ * Context type %FW_CDEV_ISO_CONTEXT_RECEIVE_MULTICHANNEL:
+ *
+ * Here, &fw_cdev_iso_packet would be more aptly named _iso_buffer_chunk since

+ * In Linux, we implement the KVP functionality in two components:
+ * 1) The kernel component which is packaged as part of the hv_utils driver
+ * is responsible for communicating with the host and responsible for
+ * implementing the host/guest protocol. 2) A user level daemon that is
+ * responsible for data gathering.
+ *
+ * Host/Guest Protocol: The host iterates over an index and expects the guest
+ * to assign a key name to the index and also return the value corresponding to
+ * the key. The host will have atmost one KVP transaction outstanding at any
+ * given point in time. The host side iteration stops when the guest returns
+ * an error. Microsoft has specified the following mapping of key names to
+ * host specified index:
+ *
+ *	Index		Key Name
+ *	0		FullyQualifiedDomainName
+ *	1		IntegrationServicesVersion
+ *	2		NetworkAddressIPv4
+ *	3		NetworkAddressIPv6
+ *	4		OSBuildNumber
+ *	5		OSName
+ *	6		OSMajorVersion
+ *	7		OSMinorVersion
+ *	8		OSVersion
+ *	9		ProcessorArchitecture
+ *
+ * The Windows host expects the Key Name and Key Value to be encoded in utf16.
+ *
+ * Guest Kernel/KVP Daemon Protocol: As noted earlier, we implement all of the
+ * data gathering functionality in a user mode daemon. The user level daemon
+ * is also responsible for binding the key name to the index as well. The
+ * kernel and user-level daemon communicate using a connector channel.
+ *
+ * The user mode component first registers with the
+ * the kernel component. Subsequently, the kernel component requests, data
+ * for the specified keys. In response to this message the user mode component
+ * fills in the value corresponding to the specified key. We overload the
+ * sequence field in the cn_msg header to define our KVP message types.
+ *
+ *
+ * The kernel component simply acts as a conduit for communication between the
+ * Windows host and the user-level daemon. The kernel component passes up the
+ * index received from the Host to the user-level daemon. If the index is
+ * valid (supported), the corresponding key as well as its
+ * value (both are strings) is returned. If the index is invalid
+ * (not supported), a NULL key string is returned.

+ * that I chose to treat the registration operation as part of the
+ * KVP operations defined by the host.
+ * Here is the level of compatibility
+ * (between the user level daemon and the kernel KVP driver) that we
+ * will implement:
+ *
+ * An older daemon will always be supported on a newer driver.

+/**
+ * struct i2c_msg - an I2C transaction segment beginning with START
+ * @addr: Slave address, either seven or ten bits.  When this is a ten
+ *	bit address, I2C_M_TEN must be set in @flags and the adapter
+ *	must support I2C_FUNC_10BIT_ADDR.
+ * @flags: I2C_M_RD is handled by all adapters.  No other flags may be
+ *	provided unless the adapter exported the relevant I2C_FUNC_*
+ *	flags through i2c_check_functionality().
+ * @len: Number of data bytes in @buf being read from or written to the
+ *	I2C slave address.  For read transactions where I2C_M_RECV_LEN
+ *	is set, the caller guarantees that this buffer can hold up to
+ *	32 bytes in addition to the initial length byte sent by the
+ *	slave (plus, if used, the SMBus PEC); and this value will be
+ *	incremented by the number of block data bytes received.
+ * @buf: The buffer into which data is read, or from which it's written.
+ *
+ * An i2c_msg is the low level representation of one segment of an I2C
+ * transaction.  It is visible to drivers in the @i2c_transfer() procedure,
+ * to userspace from i2c-dev, and to I2C adapter drivers through the
+ * @i2c_adapter.@master_xfer() method.
+ *
+ * Except when I2C "protocol mangling" is used, all I2C adapters implement
+ * the standard rules for I2C transactions.  Each transaction begins with a
+ * START.  That is followed by the slave address, and a bit encoding read
+ * versus write.  Then follow all the data bytes, possibly including a byte
+ * with SMBus PEC.  The transfer terminates with a NAK, or when all those
+ * bytes have been transferred and ACKed.  If this is the last message in a
+ * group, it is followed by a STOP.  Otherwise it is followed by the next
+ * @i2c_msg transaction segment, beginning with a (repeated) START.
+ *
+ * Alternatively, when the adapter supports I2C_FUNC_PROTOCOL_MANGLING then
+ * passing certain @flags may have changed those standard protocol behaviors.
+ * Those flags are only for use with broken/nonconforming slaves, and with
+ * adapters which are known to support the specific mangling options they
+ * need (one or more of IGNORE_NAK, NO_RD_ACK, NOSTART, and REV_DIR_ADDR).

+/**
+ * enum net_device_flags - &struct net_device flags
+ *
+ * These are the &struct net_device flags, they can be set by drivers, the
+ * kernel and some can be triggered by userspace. Userspace can query and
+ * set these flags using userspace utilities but there is also a sysfs
+ * entry available for all dev flags which can be queried and set. These flags
+ * are shared for all types of net_devices. The sysfs entries are available
+ * via /sys/class/net/<dev>/flags. Flags which can be toggled through sysfs
+ * are annotated below, note that only a few flags can be toggled and some
+ * other flags are always always preserved from the original net_device flags
+ * even if you try to set them via sysfs. Flags which are always preserved
+ * are kept under the flag grouping @IFF_VOLATILE. Flags which are volatile
+ * are annotated below as such.
+ *
+ * You should have a pretty good reason to be extending these flags.
+ *
+ * @IFF_UP: interface is up. Can be toggled through sysfs.
+ * @IFF_BROADCAST: broadcast address valid. Volatile.
+ * @IFF_DEBUG: turn on debugging. Can be toggled through sysfs.
+ * @IFF_LOOPBACK: is a loopback net. Volatile.
+ * @IFF_POINTOPOINT: interface is has p-p link. Volatile.
+ * @IFF_NOTRAILERS: avoid use of trailers. Can be toggled through sysfs.
+ *	Volatile.
+ * @IFF_RUNNING: interface RFC2863 OPER_UP. Volatile.
+ * @IFF_NOARP: no ARP protocol. Can be toggled through sysfs. Volatile.
+ * @IFF_PROMISC: receive all packets. Can be toggled through sysfs.
+ * @IFF_ALLMULTI: receive all multicast packets. Can be toggled through
+ *	sysfs.
+ * @IFF_MASTER: master of a load balancer. Volatile.
+ * @IFF_SLAVE: slave of a load balancer. Volatile.
+ * @IFF_MULTICAST: Supports multicast. Can be toggled through sysfs.
+ * @IFF_PORTSEL: can set media type. Can be toggled through sysfs.
+ * @IFF_AUTOMEDIA: auto media select active. Can be toggled through sysfs.
+ * @IFF_DYNAMIC: dialup device with changing addresses. Can be toggled
+ *	through sysfs.
+ * @IFF_LOWER_UP: driver signals L1 up. Volatile.

+ * commands the user sends and tracks the responses.  The responses
+ * will go back to the application that send the command.  If the
+ * response doesn't come back in time, the driver will return a
+ * timeout error response to the application.  Asynchronous events
+ * from the BMC event queue will go to all users bound to the driver.
+ * The incoming event queue in the BMC will automatically be flushed
+ * if it becomes full and it is queried once a second to see if
+ * anything is in it.  Incoming commands to the driver will get

+* the tone sequence.  The tone_on_time and tone_off time are in
+* 250 microsecond intervals.  A pointer to this array is passed to the
+* driver as the ce element of an IXJ_CADENCE structure.  The elements_used
+* must be set to the number of IXJ_CADENCE_ELEMENTS in the array.  The
+* termination variable defines what to do at the end of a cadence, the
+* options are to play the cadence once and stop, to repeat the last
+* element of the cadence indefinitely, or to repeat the entire cadence
+* indefinitely.  The ce variable is a pointer to the array of IXJ_TONE
+* structures.  If the freq0 variable is non-zero, the tone table contents
+* for the tone_index are updated to the frequencies and gains defined.  It
+* should be noted that DTMF tones cannot be reassigned, so if DTMF tone
+* table indexes are used in a cadence the frequency and gain variables will
+* be ignored.
+*
+* If the array elements contain frequency parameters the driver will
+* initialize the needed tone table elements and begin playing the tone,
+* there is no preset limit on the number of elements in the cadence.  If
+* there is more than one frequency used in the cadence, sequential elements
+* of different frequencies MUST use different tone table indexes.  Only one

+/*
+ * Compatibility interface for userspace libc header coordination:
+ *
+ * Define compatibility macros that are used to control the inclusion or
+ * exclusion of UAPI structures and definitions in coordination with another
+ * userspace C library.
+ *
+ * This header is intended to solve the problem of UAPI definitions that
+ * conflict with userspace definitions. If a UAPI header has such conflicting
+ * definitions then the solution is as follows:
+ *
+ * * Synchronize the UAPI header and the libc headers so either one can be
+ *   used and such that the ABI is preserved. If this is not possible then
+ *   no simple compatibility interface exists (you need to write translating
+ *   wrappers and rename things) and you can't use this interface.
+ *
+ * Then follow this process:
+ *
+ * (a) Include libc-compat.h in the UAPI header.
+ *      e.g. #include <linux/libc-compat.h>
+ *     This include must be as early as possible.
+ *
+ * (b) In libc-compat.h add enough code to detect that the comflicting
+ *     userspace libc header has been included first.
+ *
+ * (c) If the userspace libc header has been included first define a set of
+ *     guard macros of the form __UAPI_DEF_FOO and set their values to 1, else
+ *     set their values to 0.
+ *
+ * (d) Back in the UAPI header with the conflicting definitions, guard the
+ *     definitions with:
+ *     #if __UAPI_DEF_FOO
+ *       ...
+ *     #endif
+ *
+ * This fixes the situation where the linux headers are included *after* the
+ * libc headers. To fix the problem with the inclusion in the other order the
+ * userspace libc headers must be fixed like this:
+ *
+ * * For all definitions that conflict with kernel definitions wrap those
+ *   defines in the following:
+ *   #if !__UAPI_DEF_FOO
+ *     ...
+ *   #endif
+ *
+ * This prevents the redefinition of a construct already defined by the kernel.

+ * @NFC_CMD_STOP_POLL: stop polling for targets (requires
+ *	%NFC_ATTR_DEVICE_INDEX)
+ * @NFC_CMD_GET_TARGET: dump all targets found by the previous poll (requires
+ *	%NFC_ATTR_DEVICE_INDEX)
+ * @NFC_EVENT_TARGETS_FOUND: event emitted when a new target is found
+ *	(it sends %NFC_ATTR_DEVICE_INDEX)
+ * @NFC_EVENT_DEVICE_ADDED: event emitted when a new device is registred
+ *	(it sends %NFC_ATTR_DEVICE_NAME, %NFC_ATTR_DEVICE_INDEX and
+ *	%NFC_ATTR_PROTOCOLS)
+ * @NFC_EVENT_DEVICE_REMOVED: event emitted when a device is removed
+ *	(it sends %NFC_ATTR_DEVICE_INDEX)
+ * @NFC_EVENT_TM_ACTIVATED: event emitted when the adapter is activated in
+ *      target mode.
+ * @NFC_EVENT_DEVICE_DEACTIVATED: event emitted when the adapter is deactivated
+ *      from target mode.
+ * @NFC_CMD_LLC_GET_PARAMS: request LTO, RW, and MIUX parameters for a device
+ * @NFC_CMD_LLC_SET_PARAMS: set one or more of LTO, RW, and MIUX parameters for
+ *	a device. LTO must be set before the link is up otherwise -EINPROGRESS
+ *	is returned. RW and MIUX can be set at anytime and will be passed in
+ *	subsequent CONNECT and CC messages.
+ *	If one of the passed parameters is wrong none is set and -EINVAL is
+ *	returned.
+ * @NFC_CMD_ENABLE_SE: Enable the physical link to a specific secure element.
+ *	Once enabled a secure element will handle card emulation mode, i.e.
+ *	starting a poll from a device which has a secure element enabled means
+ *	we want to do SE based card emulation.
+ * @NFC_CMD_DISABLE_SE: Disable the physical link to a specific secure element.
+ * @NFC_CMD_FW_DOWNLOAD: Request to Load/flash firmware, or event to inform
+ *	that some firmware was loaded
+ * @NFC_EVENT_SE_ADDED: Event emitted when a new secure element is discovered.
+ *	This typically will be sent whenever a new NFC controller with either
+ *	an embedded SE or an UICC one connected to it through SWP.
+ * @NFC_EVENT_SE_REMOVED: Event emitted when a secure element is removed from
+ *	the system, as a consequence of e.g. an NFC controller being unplugged.
+ * @NFC_EVENT_SE_CONNECTIVITY: This event is emitted whenever a secure element
+ *	is requesting connectivity access. For example a UICC SE may need to
+ *	talk with a sleeping modem and will notify this need by sending this
+ *	event. It is then up to userspace to decide if it will wake the modem
+ *	up or not.
+ * @NFC_EVENT_SE_TRANSACTION: This event is sent when an application running on
+ *	a specific SE notifies us about the end of a transaction. The parameter
+ *	for this event is the application ID (AID).
+ * @NFC_CMD_GET_SE: Dump all discovered secure elements from an NFC controller.
+ * @NFC_CMD_SE_IO: Send/Receive APDUs to/from the selected secure element.

+ * DOC: Station handling
+ *
+ * Stations are added per interface, but a special case exists with VLAN
+ * interfaces. When a station is bound to an AP interface, it may be moved
+ * into a VLAN identified by a VLAN interface index (%NL80211_ATTR_STA_VLAN).
+ * The station is still assumed to belong to the AP interface it was added
+ * to.
+ *
+ * Station handling varies per interface type and depending on the driver's
+ * capabilities.
+ *
+ * For drivers supporting TDLS with external setup (WIPHY_FLAG_SUPPORTS_TDLS
+ * and WIPHY_FLAG_TDLS_EXTERNAL_SETUP), the station lifetime is as follows:
+ *  - a setup station entry is added, not yet authorized, without any rate
+ *    or capability information, this just exists to avoid race conditions
+ *  - when the TDLS setup is done, a single NL80211_CMD_SET_STATION is valid
+ *    to add rate and capability information to the station and at the same
+ *    time mark it authorized.
+ *  - %NL80211_TDLS_ENABLE_LINK is then used
+ *  - after this, the only valid operation is to remove it by tearing down
+ *    the TDLS link (%NL80211_TDLS_DISABLE_LINK)
+ *
+ * TODO: need more info for other interface types

+/**
+ * DOC: Frame transmission/registration support
+ *
+ * Frame transmission and registration support exists to allow userspace
+ * management entities such as wpa_supplicant react to management frames
+ * that are not being handled by the kernel. This includes, for example,
+ * certain classes of action frames that cannot be handled in the kernel
+ * for various reasons.
+ *
+ * Frame registration is done on a per-interface basis and registrations
+ * cannot be removed other than by closing the socket. It is possible to
+ * specify a registration filter to register, for example, only for a
+ * certain type of action frame. In particular with action frames, those
+ * that userspace registers for will not be returned as unhandled by the
+ * driver, so that the registered application has to take responsibility
+ * for doing that.
+ *
+ * The type of frame that can be registered for is also dependent on the
+ * driver and interface type. The frame types are advertised in wiphy
+ * attributes so applications know what to expect.
+ *
+ * NOTE: When an interface changes type while registrations are active,
+ *       these registrations are ignored until the interface type is
+ *       changed again. This means that changing the interface type can
+ *       lead to a situation that couldn't otherwise be produced, but
+ *       any such registrations will be dormant in the sense that they
+ *       will not be serviced, i.e. they will not receive any frames.
+ *
+ * Frame transmission allows userspace to send for example the required
+ * responses to action frames. It is subject to some sanity checking,
+ * but many frames can be transmitted. When a frame was transmitted, its
+ * status is indicated to the sending socket.

+ * DOC: Virtual interface / concurrency capabilities
+ *
+ * Some devices are able to operate with virtual MACs, they can have
+ * more than one virtual interface. The capability handling for this
+ * is a bit complex though, as there may be a number of restrictions
+ * on the types of concurrency that are supported.
+ *
+ * To start with, each device supports the interface types listed in
+ * the %NL80211_ATTR_SUPPORTED_IFTYPES attribute, but by listing the
+ * types there no concurrency is implied.
+ *
+ * Once concurrency is desired, more attributes must be observed:
+ * To start with, since some interface types are purely managed in
+ * software, like the AP-VLAN type in mac80211 for example, there's
+ * an additional list of these, they can be added at any time and
+ * are only restricted by some semantic restrictions (e.g. AP-VLAN
+ * cannot be added without a corresponding AP interface). This list
+ * is exported in the %NL80211_ATTR_SOFTWARE_IFTYPES attribute.
+ *
+ * Further, the list of supported combinations is exported. This is
+ * in the %NL80211_ATTR_INTERFACE_COMBINATIONS attribute. Basically,
+ * it exports a list of "groups", and at any point in time the
+ * interfaces that are currently active must fall into any one of
+ * the advertised groups. Within each group, there are restrictions
+ * on the number of interfaces of different types that are supported
+ * and also the number of different channels, along with potentially
+ * some other restrictions. See &enum nl80211_if_combination_attrs.
+ *
+ * All together, these attributes define the concurrency of virtual
+ * interfaces that a given device supports.

+ * DOC: packet coalesce support
+ *
+ * In most cases, host that receives IPv4 and IPv6 multicast/broadcast
+ * packets does not do anything with these packets. Therefore the
+ * reception of these unwanted packets causes unnecessary processing
+ * and power consumption.
+ *
+ * Packet coalesce feature helps to reduce number of received interrupts
+ * to host by buffering these packets in firmware/hardware for some
+ * predefined time. Received interrupt will be generated when one of the
+ * following events occur.
+ * a) Expiration of hardware timer whose expiration time is set to maximum
+ * coalescing delay of matching coalesce rule.
+ * b) Coalescing buffer in hardware reaches it's limit.
+ * c) Packet doesn't match any of the configured coalesce rules.
+ *
+ * User needs to configure following parameters for creating a coalesce
+ * rule.
+ * a) Maximum coalescing delay
+ * b) List of packet patterns which needs to be matched
+ * c) Condition for coalescence. pattern 'match' or 'no match'
+ * Multiple such rules can be created.

+ *	%NL80211_ATTR_IFINDEX.
+ *
+ * @NL80211_CMD_GET_REG: ask the wireless core to send us its currently set
+ *	regulatory domain. If %NL80211_ATTR_WIPHY is specified and the device
+ *	has a private regulatory domain, it will be returned. Otherwise, the
+ *	global regdomain will be returned.
+ *	A device will have a private regulatory domain if it uses the
+ *	regulatory_hint() API. Even when a private regdomain is used the channel
+ *	information will still be mended according to further hints from
+ *	the regulatory core to help with compliance. A dump version of this API
+ *	is now available which will returns the global regdomain as well as

+ *	If a wiphy is self-managed (%NL80211_ATTR_WIPHY_SELF_MANAGED_REG), then
+ *	its private regdomain is the only valid one for it. The regulatory
+ *	core is not used to help with compliance in this case.
+ * @NL80211_CMD_SET_REG: Set current regulatory domain. CRDA sends this command
+ *	after being queried by the kernel. CRDA replies by sending a regulatory
+ *	domain structure which consists of %NL80211_ATTR_REG_ALPHA set to our
+ *	current alpha2 if it found a match. It also provides
+ * 	NL80211_ATTR_REG_RULE_FLAGS, and a set of regulatory rules. Each
+ * 	regulatory rule is a nested set of attributes  given by
+ * 	%NL80211_ATTR_REG_RULE_FREQ_[START|END] and
+ * 	%NL80211_ATTR_FREQ_RANGE_MAX_BW with an attached power rule given by

+ * 	%NL80211_ATTR_REG_RULE_POWER_MAX_EIRP.
+ * @NL80211_CMD_REQ_SET_REG: ask the wireless core to set the regulatory domain
+ * 	to the specified ISO/IEC 3166-1 alpha2 country code. The core will
+ * 	store this as a valid request and then query userspace for it.
+ *
+ * @NL80211_CMD_GET_MESH_CONFIG: Get mesh networking properties for the
+ *	interface identified by %NL80211_ATTR_IFINDEX
+ *
+ * @NL80211_CMD_SET_MESH_CONFIG: Set mesh networking properties for the
+ *      interface identified by %NL80211_ATTR_IFINDEX
+ *
+ * @NL80211_CMD_SET_MGMT_EXTRA_IE: Set extra IEs for management frames. The
+ *	interface is identified with %NL80211_ATTR_IFINDEX and the management
+ *	frame subtype with %NL80211_ATTR_MGMT_SUBTYPE. The extra IE data to be
+ *	added to the end of the specified management frame is specified with
+ *	%NL80211_ATTR_IE. If the command succeeds, the requested data will be
+ *	added to all specified management frames generated by
+ *	kernel/firmware/driver.
+ *	Note: This command has been removed and it is only reserved at this
+ *	point to avoid re-using existing command number. The functionality this
+ *	command was planned for has been provided with cleaner design with the
+ *	option to specify additional IEs in NL80211_CMD_TRIGGER_SCAN,
+ *	NL80211_CMD_AUTHENTICATE, NL80211_CMD_ASSOCIATE,
+ *	NL80211_CMD_DEAUTHENTICATE, and NL80211_CMD_DISASSOCIATE.
+ *
+ * @NL80211_CMD_GET_SCAN: get scan results
+ * @NL80211_CMD_TRIGGER_SCAN: trigger a new scan with the given parameters
+ *	%NL80211_ATTR_TX_NO_CCK_RATE is used to decide whether to send the
+ *	probe requests at CCK rate or not.
+ * @NL80211_CMD_NEW_SCAN_RESULTS: scan notification (as a reply to
+ *	NL80211_CMD_GET_SCAN and on the "scan" multicast group)
+ * @NL80211_CMD_SCAN_ABORTED: scan was aborted, for unspecified reasons,
+ *	partial scan results may be available
+ *
+ * @NL80211_CMD_START_SCHED_SCAN: start a scheduled scan at certain
+ *	intervals, as specified by %NL80211_ATTR_SCHED_SCAN_INTERVAL.
+ *	Like with normal scans, if SSIDs (%NL80211_ATTR_SCAN_SSIDS)
+ *	are passed, they are used in the probe requests.  For
+ *	broadcast, a broadcast SSID must be passed (ie. an empty
+ *	string).  If no SSID is passed, no probe requests are sent and
+ *	a passive scan is performed.  %NL80211_ATTR_SCAN_FREQUENCIES,
+ *	if passed, define which channels should be scanned; if not
+ *	passed, all channels allowed for the current regulatory domain
+ *	are used.  Extra IEs can also be passed from the userspace by
+ *	using the %NL80211_ATTR_IE attribute.  The first cycle of the
+ *	scheduled scan can be delayed by %NL80211_ATTR_SCHED_SCAN_DELAY
+ *	is supplied.
+ * @NL80211_CMD_STOP_SCHED_SCAN: stop a scheduled scan. Returns -ENOENT if
+ *	scheduled scan is not running. The caller may assume that as soon
+ *	as the call returns, it is safe to start a new scheduled scan again.
+ * @NL80211_CMD_SCHED_SCAN_RESULTS: indicates that there are scheduled scan
+ *	results available.
+ * @NL80211_CMD_SCHED_SCAN_STOPPED: indicates that the scheduled scan has
+ *	stopped.  The driver may issue this event at any time during a
+ *	scheduled scan.  One reason for stopping the scan is if the hardware
+ *	does not support starting an association or a normal scan while running
+ *	a scheduled scan.  This event is also sent when the
+ *	%NL80211_CMD_STOP_SCHED_SCAN command is received or when the interface
+ *	is brought down while a scheduled scan was running.
+ *
+ * @NL80211_CMD_GET_SURVEY: get survey resuls, e.g. channel occupation
+ *      or noise level
+ * @NL80211_CMD_NEW_SURVEY_RESULTS: survey data notification (as a reply to
+ *	NL80211_CMD_GET_SURVEY and on the "scan" multicast group)
+ *
+ * @NL80211_CMD_SET_PMKSA: Add a PMKSA cache entry, using %NL80211_ATTR_MAC
+ *	(for the BSSID) and %NL80211_ATTR_PMKID.
+ * @NL80211_CMD_DEL_PMKSA: Delete a PMKSA cache entry, using %NL80211_ATTR_MAC
+ *	(for the BSSID) and %NL80211_ATTR_PMKID.
+ * @NL80211_CMD_FLUSH_PMKSA: Flush all PMKSA cache entries.
+ *
+ * @NL80211_CMD_REG_CHANGE: indicates to userspace the regulatory domain
+ * 	has been changed and provides details of the request information
+ * 	that caused the change such as who initiated the regulatory request
+ * 	(%NL80211_ATTR_REG_INITIATOR), the wiphy_idx
+ * 	(%NL80211_ATTR_REG_ALPHA2) on which the request was made from if
+ * 	the initiator was %NL80211_REGDOM_SET_BY_COUNTRY_IE or
+ * 	%NL80211_REGDOM_SET_BY_DRIVER, the type of regulatory domain
+ * 	set (%NL80211_ATTR_REG_TYPE), if the type of regulatory domain is
+ * 	%NL80211_REG_TYPE_COUNTRY the alpha2 to which we have moved on
+ * 	to (%NL80211_ATTR_REG_ALPHA2).
+ * @NL80211_CMD_REG_BEACON_HINT: indicates to userspace that an AP beacon
+ * 	has been found while world roaming thus enabling active scan or
+ * 	any mode of operation that initiates TX (beacons) on a channel
+ * 	where we would not have been able to do either before. As an example
+ * 	if you are world roaming (regulatory domain set to world or if your
+ * 	driver is using a custom world roaming regulatory domain) and while
+ * 	doing a passive scan on the 5 GHz band you find an AP there (if not
+ * 	on a DFS channel) you will now be able to actively scan for that AP
+ * 	or use AP mode on your card on that same channel. Note that this will
+ * 	never be used for channels 1-11 on the 2 GHz band as they are always
+ * 	enabled world wide. This beacon hint is only sent if your device had
+ * 	either disabled active scanning or beaconing on a channel. We send to
+ * 	userspace the wiphy on which we removed a restriction from
+ * 	(%NL80211_ATTR_WIPHY) and the channel on which this occurred
+ * 	before (%NL80211_ATTR_FREQ_BEFORE) and after (%NL80211_ATTR_FREQ_AFTER)
+ * 	the beacon hint was processed.
+ *
+ * @NL80211_CMD_AUTHENTICATE: authentication request and notification.
+ *	This command is used both as a command (request to authenticate) and
+ *	as an event on the "mlme" multicast group indicating completion of the
+ *	authentication process.
+ *	When used as a command, %NL80211_ATTR_IFINDEX is used to identify the
+ *	interface. %NL80211_ATTR_MAC is used to specify PeerSTAAddress (and
+ *	BSSID in case of station mode). %NL80211_ATTR_SSID is used to specify
+ *	the SSID (mainly for association, but is included in authentication
+ *	request, too, to help BSS selection. %NL80211_ATTR_WIPHY_FREQ is used
+ *	to specify the frequence of the channel in MHz. %NL80211_ATTR_AUTH_TYPE
+ *	is used to specify the authentication type. %NL80211_ATTR_IE is used to
+ *	define IEs (VendorSpecificInfo, but also including RSN IE and FT IEs)
+ *	to be added to the frame.
+ *	When used as an event, this reports reception of an Authentication
+ *	frame in station and IBSS modes when the local MLME processed the
+ *	frame, i.e., it was for the local STA and was received in correct
+ *	state. This is similar to MLME-AUTHENTICATE.confirm primitive in the
+ *	MLME SAP interface (kernel providing MLME, userspace SME). The
+ *	included %NL80211_ATTR_FRAME attribute contains the management frame
+ *	(including both the header and frame body, but not FCS). This event is
+ *	also used to indicate if the authentication attempt timed out. In that
+ *	case the %NL80211_ATTR_FRAME attribute is replaced with a
+ *	%NL80211_ATTR_TIMED_OUT flag (and %NL80211_ATTR_MAC to indicate which
+ *	pending authentication timed out).
+ * @NL80211_CMD_ASSOCIATE: association request and notification; like
+ *	NL80211_CMD_AUTHENTICATE but for Association and Reassociation
+ *	(similar to MLME-ASSOCIATE.request, MLME-REASSOCIATE.request,
+ *	MLME-ASSOCIATE.confirm or MLME-REASSOCIATE.confirm primitives).
+ * @NL80211_CMD_DEAUTHENTICATE: deauthentication request and notification; like
+ *	NL80211_CMD_AUTHENTICATE but for Deauthentication frames (similar to
+ *	MLME-DEAUTHENTICATION.request and MLME-DEAUTHENTICATE.indication
+ *	primitives).
+ * @NL80211_CMD_DISASSOCIATE: disassociation request and notification; like
+ *	NL80211_CMD_AUTHENTICATE but for Disassociation frames (similar to
+ *	MLME-DISASSOCIATE.request and MLME-DISASSOCIATE.indication primitives).
+ *
+ * @NL80211_CMD_MICHAEL_MIC_FAILURE: notification of a locally detected Michael
+ *	MIC (part of TKIP) failure; sent on the "mlme" multicast group; the
+ *	event includes %NL80211_ATTR_MAC to describe the source MAC address of
+ *	the frame with invalid MIC, %NL80211_ATTR_KEY_TYPE to show the key
+ *	type, %NL80211_ATTR_KEY_IDX to indicate the key identifier, and
+ *	%NL80211_ATTR_KEY_SEQ to indicate the TSC value of the frame; this
+ *	event matches with MLME-MICHAELMICFAILURE.indication() primitive
+ *
+ * @NL80211_CMD_JOIN_IBSS: Join a new IBSS -- given at least an SSID and a
+ *	FREQ attribute (for the initial frequency if no peer can be found)
+ *	and optionally a MAC (as BSSID) and FREQ_FIXED attribute if those
+ *	should be fixed rather than automatically determined. Can only be
+ *	executed on a network interface that is UP, and fixed BSSID/FREQ
+ *	may be rejected. Another optional parameter is the beacon interval,
+ *	given in the %NL80211_ATTR_BEACON_INTERVAL attribute, which if not
+ *	given defaults to 100 TU (102.4ms).
+ * @NL80211_CMD_LEAVE_IBSS: Leave the IBSS -- no special arguments, the IBSS is
+ *	determined by the network interface.
+ *
+ * @NL80211_CMD_TESTMODE: testmode command, takes a wiphy (or ifindex) attribute
+ *	to identify the device, and the TESTDATA blob attribute to pass through
+ *	to the driver.
+ *
+ * @NL80211_CMD_CONNECT: connection request and notification; this command
+ *	requests to connect to a specified network but without separating
+ *	auth and assoc steps. For this, you need to specify the SSID in a
+ *	%NL80211_ATTR_SSID attribute, and can optionally specify the association
+ *	IEs in %NL80211_ATTR_IE, %NL80211_ATTR_AUTH_TYPE, %NL80211_ATTR_USE_MFP,
+ *	%NL80211_ATTR_MAC, %NL80211_ATTR_WIPHY_FREQ, %NL80211_ATTR_CONTROL_PORT,
+ *	%NL80211_ATTR_CONTROL_PORT_ETHERTYPE,
+ *	%NL80211_ATTR_CONTROL_PORT_NO_ENCRYPT, %NL80211_ATTR_MAC_HINT, and
+ *	%NL80211_ATTR_WIPHY_FREQ_HINT.
+ *	If included, %NL80211_ATTR_MAC and %NL80211_ATTR_WIPHY_FREQ are
+ *	restrictions on BSS selection, i.e., they effectively prevent roaming
+ *	within the ESS. %NL80211_ATTR_MAC_HINT and %NL80211_ATTR_WIPHY_FREQ_HINT
+ *	can be included to provide a recommendation of the initial BSS while
+ *	allowing the driver to roam to other BSSes within the ESS and also to
+ *	ignore this recommendation if the indicated BSS is not ideal. Only one
+ *	set of BSSID,frequency parameters is used (i.e., either the enforcing
+ *	%NL80211_ATTR_MAC,%NL80211_ATTR_WIPHY_FREQ or the less strict
+ *	%NL80211_ATTR_MAC_HINT and %NL80211_ATTR_WIPHY_FREQ_HINT).
+ *	Background scan period can optionally be
+ *	specified in %NL80211_ATTR_BG_SCAN_PERIOD,
+ *	if not specified default background scan configuration
+ *	in driver is used and if period value is 0, bg scan will be disabled.
+ *	This attribute is ignored if driver does not support roam scan.
+ *	It is also sent as an event, with the BSSID and response IEs when the
+ *	connection is established or failed to be established. This can be
+ *	determined by the STATUS_CODE attribute.
+ * @NL80211_CMD_ROAM: request that the card roam (currently not implemented),
+ *	sent as an event when the card/driver roamed by itself.
+ * @NL80211_CMD_DISCONNECT: drop a given connection; also used to notify
+ *	userspace that a connection was dropped by the AP or due to other
+ *	reasons, for this the %NL80211_ATTR_DISCONNECTED_BY_AP and
+ *	%NL80211_ATTR_REASON_CODE attributes are used.
+ *
+ * @NL80211_CMD_SET_WIPHY_NETNS: Set a wiphy's netns. Note that all devices
+ *	associated with this wiphy must be down and will follow.
+ *
+ * @NL80211_CMD_REMAIN_ON_CHANNEL: Request to remain awake on the specified
+ *	channel for the specified amount of time. This can be used to do
+ *	off-channel operations like transmit a Public Action frame and wait for
+ *	a response while being associated to an AP on another channel.
+ *	%NL80211_ATTR_IFINDEX is used to specify which interface (and thus
+ *	radio) is used. %NL80211_ATTR_WIPHY_FREQ is used to specify the
+ *	frequency for the operation.
+ *	%NL80211_ATTR_DURATION is used to specify the duration in milliseconds
+ *	to remain on the channel. This command is also used as an event to
+ *	notify when the requested duration starts (it may take a while for the
+ *	driver to schedule this time due to other concurrent needs for the
+ *	radio).
+ *	When called, this operation returns a cookie (%NL80211_ATTR_COOKIE)
+ *	that will be included with any events pertaining to this request;
+ *	the cookie is also used to cancel the request.
+ * @NL80211_CMD_CANCEL_REMAIN_ON_CHANNEL: This command can be used to cancel a
+ *	pending remain-on-channel duration if the desired operation has been
+ *	completed prior to expiration of the originally requested duration.
+ *	%NL80211_ATTR_WIPHY or %NL80211_ATTR_IFINDEX is used to specify the
+ *	radio. The %NL80211_ATTR_COOKIE attribute must be given as well to
+ *	uniquely identify the request.
+ *	This command is also used as an event to notify when a requested
+ *	remain-on-channel duration has expired.
+ *
+ * @NL80211_CMD_SET_TX_BITRATE_MASK: Set the mask of rates to be used in TX
+ *	rate selection. %NL80211_ATTR_IFINDEX is used to specify the interface
+ *	and @NL80211_ATTR_TX_RATES the set of allowed rates.
+ *
+ * @NL80211_CMD_REGISTER_FRAME: Register for receiving certain mgmt frames
+ *	(via @NL80211_CMD_FRAME) for processing in userspace. This command
+ *	requires an interface index, a frame type attribute (optional for
+ *	backward compatibility reasons, if not given assumes action frames)
+ *	and a match attribute containing the first few bytes of the frame
+ *	that should match, e.g. a single byte for only a category match or
+ *	four bytes for vendor frames including the OUI. The registration
+ *	cannot be dropped, but is removed automatically when the netlink
+ *	socket is closed. Multiple registrations can be made.
+ * @NL80211_CMD_REGISTER_ACTION: Alias for @NL80211_CMD_REGISTER_FRAME for
+ *	backward compatibility
+ * @NL80211_CMD_FRAME: Management frame TX request and RX notification. This
+ *	command is used both as a request to transmit a management frame and
+ *	as an event indicating reception of a frame that was not processed in
+ *	kernel code, but is for us (i.e., which may need to be processed in a
+ *	user space application). %NL80211_ATTR_FRAME is used to specify the
+ *	frame contents (including header). %NL80211_ATTR_WIPHY_FREQ is used
+ *	to indicate on which channel the frame is to be transmitted or was
+ *	received. If this channel is not the current channel (remain-on-channel
+ *	or the operational channel) the device will switch to the given channel
+ *	and transmit the frame, optionally waiting for a response for the time
+ *	specified using %NL80211_ATTR_DURATION. When called, this operation
+ *	returns a cookie (%NL80211_ATTR_COOKIE) that will be included with the
+ *	TX status event pertaining to the TX request.
+ *	%NL80211_ATTR_TX_NO_CCK_RATE is used to decide whether to send the
+ *	management frames at CCK rate or not in 2GHz band.
+ *	%NL80211_ATTR_CSA_C_OFFSETS_TX is an array of offsets to CSA
+ *	counters which will be updated to the current value. This attribute
+ *	is used during CSA period.
+ * @NL80211_CMD_FRAME_WAIT_CANCEL: When an off-channel TX was requested, this
+ *	command may be used with the corresponding cookie to cancel the wait
+ *	time if it is known that it is no longer necessary.
+ * @NL80211_CMD_ACTION: Alias for @NL80211_CMD_FRAME for backward compatibility.
+ * @NL80211_CMD_FRAME_TX_STATUS: Report TX status of a management frame
+ *	transmitted with %NL80211_CMD_FRAME. %NL80211_ATTR_COOKIE identifies
+ *	the TX command and %NL80211_ATTR_FRAME includes the contents of the
+ *	frame. %NL80211_ATTR_ACK flag is included if the recipient acknowledged
+ *	the frame.
+ * @NL80211_CMD_ACTION_TX_STATUS: Alias for @NL80211_CMD_FRAME_TX_STATUS for
+ *	backward compatibility.
+ *
+ * @NL80211_CMD_SET_POWER_SAVE: Set powersave, using %NL80211_ATTR_PS_STATE
+ * @NL80211_CMD_GET_POWER_SAVE: Get powersave status in %NL80211_ATTR_PS_STATE
+ *
+ * @NL80211_CMD_SET_CQM: Connection quality monitor configuration. This command
+ *	is used to configure connection quality monitoring notification trigger
+ *	levels.
+ * @NL80211_CMD_NOTIFY_CQM: Connection quality monitor notification. This
+ *	command is used as an event to indicate the that a trigger level was
+ *	reached.
+ * @NL80211_CMD_SET_CHANNEL: Set the channel (using %NL80211_ATTR_WIPHY_FREQ
+ *	and the attributes determining channel width) the given interface
+ *	(identifed by %NL80211_ATTR_IFINDEX) shall operate on.
+ *	In case multiple channels are supported by the device, the mechanism
+ *	with which it switches channels is implementation-defined.
+ *	When a monitor interface is given, it can only switch channel while
+ *	no other interfaces are operating to avoid disturbing the operation
+ *	of any other interfaces, and other interfaces will again take
+ *	precedence when they are used.
+ *
+ * @NL80211_CMD_SET_WDS_PEER: Set the MAC address of the peer on a WDS interface.
+ *
+ * @NL80211_CMD_JOIN_MESH: Join a mesh. The mesh ID must be given, and initial
+ *	mesh config parameters may be given.
+ * @NL80211_CMD_LEAVE_MESH: Leave the mesh network -- no special arguments, the
+ *	network is determined by the network interface.
+ *
+ * @NL80211_CMD_UNPROT_DEAUTHENTICATE: Unprotected deauthentication frame
+ *	notification. This event is used to indicate that an unprotected
+ *	deauthentication frame was dropped when MFP is in use.
+ * @NL80211_CMD_UNPROT_DISASSOCIATE: Unprotected disassociation frame
+ *	notification. This event is used to indicate that an unprotected
+ *	disassociation frame was dropped when MFP is in use.
+ *
+ * @NL80211_CMD_NEW_PEER_CANDIDATE: Notification on the reception of a
+ *      beacon or probe response from a compatible mesh peer.  This is only
+ *      sent while no station information (sta_info) exists for the new peer
+ *      candidate and when @NL80211_MESH_SETUP_USERSPACE_AUTH,
+ *      @NL80211_MESH_SETUP_USERSPACE_AMPE, or
+ *      @NL80211_MESH_SETUP_USERSPACE_MPM is set.  On reception of this
+ *      notification, userspace may decide to create a new station
+ *      (@NL80211_CMD_NEW_STATION).  To stop this notification from
+ *      reoccurring, the userspace authentication daemon may want to create the
+ *      new station with the AUTHENTICATED flag unset and maybe change it later
+ *      depending on the authentication result.
+ *
+ * @NL80211_CMD_GET_WOWLAN: get Wake-on-Wireless-LAN (WoWLAN) settings.
+ * @NL80211_CMD_SET_WOWLAN: set Wake-on-Wireless-LAN (WoWLAN) settings.
+ *	Since wireless is more complex than wired ethernet, it supports
+ *	various triggers. These triggers can be configured through this
+ *	command with the %NL80211_ATTR_WOWLAN_TRIGGERS attribute. For
+ *	more background information, see
+ *	http://wireless.kernel.org/en/users/Documentation/WoWLAN.
+ *	The @NL80211_CMD_SET_WOWLAN command can also be used as a notification
+ *	from the driver reporting the wakeup reason. In this case, the
+ *	@NL80211_ATTR_WOWLAN_TRIGGERS attribute will contain the reason
+ *	for the wakeup, if it was caused by wireless. If it is not present
+ *	in the wakeup notification, the wireless device didn't cause the
+ *	wakeup but reports that it was woken up.
+ *
+ * @NL80211_CMD_SET_REKEY_OFFLOAD: This command is used give the driver
+ *	the necessary information for supporting GTK rekey offload. This
+ *	feature is typically used during WoWLAN. The configuration data
+ *	is contained in %NL80211_ATTR_REKEY_DATA (which is nested and
+ *	contains the data in sub-attributes). After rekeying happened,
+ *	this command may also be sent by the driver as an MLME event to
+ *	inform userspace of the new replay counter.
+ *
+ * @NL80211_CMD_PMKSA_CANDIDATE: This is used as an event to inform userspace
+ *	of PMKSA caching dandidates.
+ *
+ * @NL80211_CMD_TDLS_OPER: Perform a high-level TDLS command (e.g. link setup).
+ *	In addition, this can be used as an event to request userspace to take
+ *	actions on TDLS links (set up a new link or tear down an existing one).
+ *	In such events, %NL80211_ATTR_TDLS_OPERATION indicates the requested
+ *	operation, %NL80211_ATTR_MAC contains the peer MAC address, and
+ *	%NL80211_ATTR_REASON_CODE the reason code to be used (only with
+ *	%NL80211_TDLS_TEARDOWN).
+ * @NL80211_CMD_TDLS_MGMT: Send a TDLS management frame. The
+ *	%NL80211_ATTR_TDLS_ACTION attribute determines the type of frame to be
+ *	sent. Public Action codes (802.11-2012 8.1.5.1) will be sent as
+ *	802.11 management frames, while TDLS action codes (802.11-2012
+ *	8.5.13.1) will be encapsulated and sent as data frames. The currently
+ *	supported Public Action code is %WLAN_PUB_ACTION_TDLS_DISCOVER_RES
+ *	and the currently supported TDLS actions codes are given in
+ *	&enum ieee80211_tdls_actioncode.
+ *
+ * @NL80211_CMD_UNEXPECTED_FRAME: Used by an application controlling an AP
+ *	(or GO) interface (i.e. hostapd) to ask for unexpected frames to
+ *	implement sending deauth to stations that send unexpected class 3
+ *	frames. Also used as the event sent by the kernel when such a frame
+ *	is received.
+ *	For the event, the %NL80211_ATTR_MAC attribute carries the TA and
+ *	other attributes like the interface index are present.
+ *	If used as the command it must have an interface index and you can
+ *	only unsubscribe from the event by closing the socket. Subscription
+ *	is also for %NL80211_CMD_UNEXPECTED_4ADDR_FRAME events.
+ *
+ * @NL80211_CMD_UNEXPECTED_4ADDR_FRAME: Sent as an event indicating that the
+ *	associated station identified by %NL80211_ATTR_MAC sent a 4addr frame
+ *	and wasn't already in a 4-addr VLAN. The event will be sent similarly
+ *	to the %NL80211_CMD_UNEXPECTED_FRAME event, to the same listener.
+ *
+ * @NL80211_CMD_PROBE_CLIENT: Probe an associated station on an AP interface
+ *	by sending a null data frame to it and reporting when the frame is
+ *	acknowleged. This is used to allow timing out inactive clients. Uses
+ *	%NL80211_ATTR_IFINDEX and %NL80211_ATTR_MAC. The command returns a
+ *	direct reply with an %NL80211_ATTR_COOKIE that is later used to match
+ *	up the event with the request. The event includes the same data and
+ *	has %NL80211_ATTR_ACK set if the frame was ACKed.
+ *
+ * @NL80211_CMD_REGISTER_BEACONS: Register this socket to receive beacons from
+ *	other BSSes when any interfaces are in AP mode. This helps implement
+ *	OLBC handling in hostapd. Beacons are reported in %NL80211_CMD_FRAME
+ *	messages. Note that per PHY only one application may register.
+ *
+ * @NL80211_CMD_SET_NOACK_MAP: sets a bitmap for the individual TIDs whether
+ *      No Acknowledgement Policy should be applied.
+ *
+ * @NL80211_CMD_CH_SWITCH_NOTIFY: An AP or GO may decide to switch channels
+ *	independently of the userspace SME, send this event indicating
+ *	%NL80211_ATTR_IFINDEX is now on %NL80211_ATTR_WIPHY_FREQ and the
+ *	attributes determining channel width.  This indication may also be
+ *	sent when a remotely-initiated switch (e.g., when a STA receives a CSA
+ *	from the remote AP) is completed;
+ *
+ * @NL80211_CMD_CH_SWITCH_STARTED_NOTIFY: Notify that a channel switch
+ *	has been started on an interface, regardless of the initiator
+ *	(ie. whether it was requested from a remote device or
+ *	initiated on our own).  It indicates that
+ *	%NL80211_ATTR_IFINDEX will be on %NL80211_ATTR_WIPHY_FREQ
+ *	after %NL80211_ATTR_CH_SWITCH_COUNT TBTT's.  The userspace may
+ *	decide to react to this indication by requesting other
+ *	interfaces to change channel as well.
+ *
+ * @NL80211_CMD_START_P2P_DEVICE: Start the given P2P Device, identified by
+ *	its %NL80211_ATTR_WDEV identifier. It must have been created with
+ *	%NL80211_CMD_NEW_INTERFACE previously. After it has been started, the
+ *	P2P Device can be used for P2P operations, e.g. remain-on-channel and
+ *	public action frame TX.
+ * @NL80211_CMD_STOP_P2P_DEVICE: Stop the given P2P Device, identified by
+ *	its %NL80211_ATTR_WDEV identifier.
+ *
+ * @NL80211_CMD_CONN_FAILED: connection request to an AP failed; used to
+ *	notify userspace that AP has rejected the connection request from a
+ *	station, due to particular reason. %NL80211_ATTR_CONN_FAILED_REASON
+ *	is used for this.
+ *
+ * @NL80211_CMD_SET_MCAST_RATE: Change the rate used to send multicast frames
+ *	for IBSS or MESH vif.
+ *
+ * @NL80211_CMD_SET_MAC_ACL: sets ACL for MAC address based access control.
+ *	This is to be used with the drivers advertising the support of MAC
+ *	address based access control. List of MAC addresses is passed in
+ *	%NL80211_ATTR_MAC_ADDRS and ACL policy is passed in
+ *	%NL80211_ATTR_ACL_POLICY. Driver will enable ACL with this list, if it
+ *	is not already done. The new list will replace any existing list. Driver
+ *	will clear its ACL when the list of MAC addresses passed is empty. This
+ *	command is used in AP/P2P GO mode. Driver has to make sure to clear its
+ *	ACL list during %NL80211_CMD_STOP_AP.
+ *
+ * @NL80211_CMD_RADAR_DETECT: Start a Channel availability check (CAC). Once
+ *	a radar is detected or the channel availability scan (CAC) has finished
+ *	or was aborted, or a radar was detected, usermode will be notified with
+ *	this event. This command is also used to notify userspace about radars
+ *	while operating on this channel.
+ *	%NL80211_ATTR_RADAR_EVENT is used to inform about the type of the
+ *	event.
+ *
+ * @NL80211_CMD_GET_PROTOCOL_FEATURES: Get global nl80211 protocol features,
+ *	i.e. features for the nl80211 protocol rather than device features.
+ *	Returns the features in the %NL80211_ATTR_PROTOCOL_FEATURES bitmap.
+ *
+ * @NL80211_CMD_UPDATE_FT_IES: Pass down the most up-to-date Fast Transition
+ *	Information Element to the WLAN driver
+ *
+ * @NL80211_CMD_FT_EVENT: Send a Fast transition event from the WLAN driver
+ *	to the supplicant. This will carry the target AP's MAC address along
+ *	with the relevant Information Elements. This event is used to report
+ *	received FT IEs (MDIE, FTIE, RSN IE, TIE, RICIE).
+ *
+ * @NL80211_CMD_CRIT_PROTOCOL_START: Indicates user-space will start running
+ *	a critical protocol that needs more reliability in the connection to
+ *	complete.
+ *
+ * @NL80211_CMD_CRIT_PROTOCOL_STOP: Indicates the connection reliability can
+ *	return back to normal.
+ *
+ * @NL80211_CMD_GET_COALESCE: Get currently supported coalesce rules.
+ * @NL80211_CMD_SET_COALESCE: Configure coalesce rules or clear existing rules.
+ *
+ * @NL80211_CMD_CHANNEL_SWITCH: Perform a channel switch by announcing the
+ *	the new channel information (Channel Switch Announcement - CSA)
+ *	in the beacon for some time (as defined in the
+ *	%NL80211_ATTR_CH_SWITCH_COUNT parameter) and then change to the
+ *	new channel. Userspace provides the new channel information (using
+ *	%NL80211_ATTR_WIPHY_FREQ and the attributes determining channel
+ *	width). %NL80211_ATTR_CH_SWITCH_BLOCK_TX may be supplied to inform
+ *	other station that transmission must be blocked until the channel
+ *	switch is complete.
+ *
+ * @NL80211_CMD_VENDOR: Vendor-specified command/event. The command is specified
+ *	by the %NL80211_ATTR_VENDOR_ID attribute and a sub-command in
+ *	%NL80211_ATTR_VENDOR_SUBCMD. Parameter(s) can be transported in
+ *	%NL80211_ATTR_VENDOR_DATA.
+ *	For feature advertisement, the %NL80211_ATTR_VENDOR_DATA attribute is
+ *	used in the wiphy data as a nested attribute containing descriptions
+ *	(&struct nl80211_vendor_cmd_info) of the supported vendor commands.
+ *	This may also be sent as an event with the same attributes.
+ *
+ * @NL80211_CMD_SET_QOS_MAP: Set Interworking QoS mapping for IP DSCP values.
+ *	The QoS mapping information is included in %NL80211_ATTR_QOS_MAP. If
+ *	that attribute is not included, QoS mapping is disabled. Since this
+ *	QoS mapping is relevant for IP packets, it is only valid during an
+ *	association. This is cleared on disassociation and AP restart.
+ *
+ * @NL80211_CMD_ADD_TX_TS: Ask the kernel to add a traffic stream for the given
+ *	%NL80211_ATTR_TSID and %NL80211_ATTR_MAC with %NL80211_ATTR_USER_PRIO
+ *	and %NL80211_ATTR_ADMITTED_TIME parameters.
+ *	Note that the action frame handshake with the AP shall be handled by
+ *	userspace via the normal management RX/TX framework, this only sets
+ *	up the TX TS in the driver/device.
+ *	If the admitted time attribute is not added then the request just checks
+ *	if a subsequent setup could be successful, the intent is to use this to
+ *	avoid setting up a session with the AP when local restrictions would
+ *	make that impossible. However, the subsequent "real" setup may still
+ *	fail even if the check was successful.
+ * @NL80211_CMD_DEL_TX_TS: Remove an existing TS with the %NL80211_ATTR_TSID
+ *	and %NL80211_ATTR_MAC parameters. It isn't necessary to call this
+ *	before removing a station entry entirely, or before disassociating
+ *	or similar, cleanup will happen in the driver/device in this case.
+ *
+ * @NL80211_CMD_GET_MPP: Get mesh path attributes for mesh proxy path to
+ *	destination %NL80211_ATTR_MAC on the interface identified by
+ *	%NL80211_ATTR_IFINDEX.
+ *
+ * @NL80211_CMD_JOIN_OCB: Join the OCB network. The center frequency and
+ *	bandwidth of a channel must be given.
+ * @NL80211_CMD_LEAVE_OCB: Leave the OCB network -- no special arguments, the
+ *	network is determined by the network interface.
+ *
+ * @NL80211_CMD_TDLS_CHANNEL_SWITCH: Start channel-switching with a TDLS peer,
+ *	identified by the %NL80211_ATTR_MAC parameter. A target channel is
+ *	provided via %NL80211_ATTR_WIPHY_FREQ and other attributes determining
+ *	channel width/type. The target operating class is given via
+ *	%NL80211_ATTR_OPER_CLASS.
+ *	The driver is responsible for continually initiating channel-switching
+ *	operations and returning to the base channel for communication with the
+ *	AP.
+ * @NL80211_CMD_TDLS_CANCEL_CHANNEL_SWITCH: Stop channel-switching with a TDLS
+ *	peer given by %NL80211_ATTR_MAC. Both peers must be on the base channel
+ *	when this command completes.
+ *
+ * @NL80211_CMD_WIPHY_REG_CHANGE: Similar to %NL80211_CMD_REG_CHANGE, but used
+ *	as an event to indicate changes for devices with wiphy-specific regdom
+ *	management.
+ *
+ * @NL80211_CMD_MAX: highest used command number
+ * @__NL80211_CMD_AFTER_LAST: internal use

+ *
+ * @NL80211_ATTR_OFFCHANNEL_TX_OK: For management frame TX, the frame may be

+ *
+ * @NL80211_ATTR_KEY_DEFAULT_TYPES: A nested attribute containing flags

+ *	able to ignore them by itself.
+ *	Thus, the implementation is somewhat hardware-dependent, but
+ *	this is only an optimization and the userspace application
+ *	needs to handle all the non-filtered results anyway.
+ *	If the match attributes don't make sense when combined with
+ *	the values passed in @NL80211_ATTR_SCAN_SSIDS (eg. if an SSID
+ *	is included in the probe request, but the match attributes
+ *	will never let it go through), -EINVAL may be returned.

+ * DOC: TCP connection wakeup
+ *
+ * Some devices can establish a TCP connection in order to be woken up by a
+ * packet coming in from outside their network segment, or behind NAT. If
+ * configured, the device will establish a TCP connection to the given
+ * service, and periodically send data to that service. The first data
+ * packet is usually transmitted after SYN/ACK, also ACKing the SYN/ACK.
+ * The data packets can optionally include a (little endian) sequence
+ * number (in the TCP payload!) that is generated by the device, and, also
+ * optionally, a token from a list of tokens. This serves as a keep-alive
+ * with the service, and for NATed connections, etc.
+ *
+ * During this keep-alive period, the server doesn't send any data to the
+ * client. When receiving data, it is compared against the wakeup pattern
+ * (and mask) and if it matches, the host is woken up. Similarly, if the
+ * connection breaks or cannot be established to start with, the host is
+ * also woken up.
+ *
+ * Developer's note: ARP offload is required for this, otherwise TCP
+ * response packets might not go through correctly.

+ * @NL80211_FEATURE_HT_IBSS: This driver supports IBSS with HT datarates.
+ * @NL80211_FEATURE_INACTIVITY_TIMER: This driver takes care of freeing up

+ * @NL80211_FEATURE_CELL_BASE_REG_HINTS: This driver has been tested
+ *	to work properly to suppport receiving regulatory hints from
+ *	cellular base stations.
+ * @NL80211_FEATURE_P2P_DEVICE_NEEDS_CHANNEL: (no longer available, only
+ *	here to reserve the value for API/ABI compatibility)
+ * @NL80211_FEATURE_SAE: This driver supports simultaneous authentication of
+ *	equals (SAE) with user space SME (NL80211_CMD_AUTHENTICATE) in station
+ *	mode
+ * @NL80211_FEATURE_LOW_PRIORITY_SCAN: This driver supports low priority scan
+ * @NL80211_FEATURE_SCAN_FLUSH: Scan flush is supported
+ * @NL80211_FEATURE_AP_SCAN: Support scanning using an AP vif
+ * @NL80211_FEATURE_VIF_TXPOWER: The driver supports per-vif TX power setting
+ * @NL80211_FEATURE_NEED_OBSS_SCAN: The driver expects userspace to perform
+ *	OBSS scans and generate 20/40 BSS coex reports. This flag is used only
+ *	for drivers implementing the CONNECT API, for AUTH/ASSOC it is implied.
+ * @NL80211_FEATURE_P2P_GO_CTWIN: P2P GO implementation supports CT Window
+ *	setting
+ * @NL80211_FEATURE_P2P_GO_OPPPS: P2P GO implementation supports opportunistic
+ *	powersave
+ * @NL80211_FEATURE_FULL_AP_CLIENT_STATE: The driver supports full state
+ *	transitions for AP clients. Without this flag (and if the driver
+ *	doesn't have the AP SME in the device) the driver supports adding
+ *	stations only when they're associated and adds them in associated
+ *	state (to later be transitioned into authorized), with this flag
+ *	they should be added before even sending the authentication reply
+ *	and then transitioned into authenticated, associated and authorized
+ *	states using station flags.
+ *	Note that even for drivers that support this, the default is to add
+ *	stations in authenticated/associated state, so to add unauthenticated
+ *	stations the authenticated/associated bits have to be set in the mask.
+ * @NL80211_FEATURE_ADVERTISE_CHAN_LIMITS: cfg80211 advertises channel limits
+ *	(HT40, VHT 80/160 MHz) if this flag is set
+ * @NL80211_FEATURE_USERSPACE_MPM: This driver supports a userspace Mesh
+ *	Peering Management entity which may be implemented by registering for
+ *	beacons or NL80211_CMD_NEW_PEER_CANDIDATE events. The mesh beacon is
+ *	still generated by the driver.
+ * @NL80211_FEATURE_ACTIVE_MONITOR: This driver supports an active monitor
+ *	interface. An active monitor interface behaves like a normal monitor
+ *	interface, but gets added to the driver. It ensures that incoming
+ *	unicast packets directed at the configured interface address get ACKed.
+ * @NL80211_FEATURE_AP_MODE_CHAN_WIDTH_CHANGE: This driver supports dynamic
+ *	channel bandwidth change (e.g., HT 20 <-> 40 MHz channel) during the
+ *	lifetime of a BSS.
+ * @NL80211_FEATURE_DS_PARAM_SET_IE_IN_PROBES: This device adds a DS Parameter
+ *	Set IE to probe requests.

+ *	to probe requests.
+ * @NL80211_FEATURE_QUIET: This device, in client mode, supports Quiet Period
+ *	requests sent to it by an AP.
+ * @NL80211_FEATURE_TX_POWER_INSERTION: This device is capable of inserting the
+ *	current tx power value into the TPC Report IE in the spectrum
+ *	management TPC Report action frame, and in the Radio Measurement Link
+ *	Measurement Report action frame.
+ * @NL80211_FEATURE_ACKTO_ESTIMATION: This driver supports dynamic ACK timeout
+ *	estimation (dynack). %NL80211_ATTR_WIPHY_DYN_ACK flag attribute is used
+ *	to enable dynack.
+ * @NL80211_FEATURE_STATIC_SMPS: Device supports static spatial
+ *	multiplexing powersave, ie. can turn off all but one chain
+ *	even on HT connections that should be using more chains.
+ * @NL80211_FEATURE_DYNAMIC_SMPS: Device supports dynamic spatial
+ *	multiplexing powersave, ie. can turn off all but one chain
+ *	and then wake the rest up as required after, for example,
+ *	rts/cts handshake.
+ * @NL80211_FEATURE_SUPPORTS_WMM_ADMISSION: the device supports setting up WMM
+ *	TSPEC sessions (TID aka TSID 0-7) with the %NL80211_CMD_ADD_TX_TS
+ *	command. Standard IEEE 802.11 TSPEC setup is not yet supported, it
+ *	needs to be able to handle Block-Ack agreements and other things.
+ * @NL80211_FEATURE_MAC_ON_CREATE: Device supports configuring
+ *	the vif's MAC address upon creation.
+ *	See 'macaddr' field in the vif_params (cfg80211.h).
+ * @NL80211_FEATURE_TDLS_CHANNEL_SWITCH: Driver supports channel switching when
+ *	operating as a TDLS peer.
+ * @NL80211_FEATURE_SCAN_RANDOM_MAC_ADDR: This device/driver supports using a

+/* 	pg.h (c) 1998  Grant R. Guenther <grant@torque.net>
+ 		       Under the terms of the GNU General Public License
+
+
+	pg.h defines the user interface to the generic ATAPI packet
+        command driver for parallel port ATAPI devices (pg). The
+	driver is loosely modelled after the generic SCSI driver, sg,
+	although the actual interface is different.
+
+	The pg driver provides a simple character device interface for
+        sending ATAPI commands to a device.  With the exception of the
+	ATAPI reset operation, all operations are performed by a pair
+        of read and write operations to the appropriate /dev/pgN device.
+	A write operation delivers a command and any outbound data in
+        a single buffer.  Normally, the write will succeed unless the
+        device is offline or malfunctioning, or there is already another
+	command pending.  If the write succeeds, it should be followed
+        immediately by a read operation, to obtain any returned data and
+        status information.  A read will fail if there is no operation
+        in progress.
+
+	As a special case, the device can be reset with a write operation,
+        and in this case, no following read is expected, or permitted.
+
+	There are no ioctl() operations.  Any single operation
+	may transfer at most PG_MAX_DATA bytes.  Note that the driver must
+        copy the data through an internal buffer.  In keeping with all
+	current ATAPI devices, command packets are assumed to be exactly
+	12 bytes in length.
+
+	To permit future changes to this interface, the headers in the
+	read and write buffers contain a single character "magic" flag.
+        Currently this flag must be the character "P".

+ * Ring Design
+ * -----------
+ *
+ * The mmaped area is divided into three parts:
+ * 1) The mailbox (struct tcmu_mailbox, below)
+ * 2) The command ring
+ * 3) Everything beyond the command ring (data)
+ *
+ * The mailbox tells userspace the offset of the command ring from the
+ * start of the shared memory region, and how big the command ring is.
+ *
+ * The kernel passes SCSI commands to userspace by putting a struct
+ * tcmu_cmd_entry in the ring, updating mailbox->cmd_head, and poking
+ * userspace via uio's interrupt mechanism.
+ *
+ * tcmu_cmd_entry contains a header. If the header type is PAD,
+ * userspace should skip hdr->length bytes (mod cmdr_size) to find the
+ * next cmd_entry.
+ *
+ * Otherwise, the entry will contain offsets into the mmaped area that
+ * contain the cdb and data buffers -- the latter accessible via the
+ * iov array. iov addresses are also offsets into the shared area.
+ *
+ * When userspace is completed handling the command, set
+ * entry->rsp.scsi_status, fill in rsp.sense_buffer if appropriate,
+ * and also set mailbox->cmd_tail equal to the old cmd_tail plus
+ * hdr->length, mod cmdr_size. If cmd_tail doesn't equal cmd_head, it
+ * should process the next packet the same way, and so on.

+ * enum wimax_st - The different states of a WiMAX device
+ * @__WIMAX_ST_NULL: The device structure has been allocated and zeroed,
+ *     but still wimax_dev_add() hasn't been called. There is no state.
+ *
+ * @WIMAX_ST_DOWN: The device has been registered with the WiMAX and
+ *     networking stacks, but it is not initialized (normally that is
+ *     done with 'ifconfig DEV up' [or equivalent], which can upload
+ *     firmware and enable communications with the device).
+ *     In this state, the device is powered down and using as less
+ *     power as possible.
+ *     This state is the default after a call to wimax_dev_add(). It
+ *     is ok to have drivers move directly to %WIMAX_ST_UNINITIALIZED
+ *     or %WIMAX_ST_RADIO_OFF in _probe() after the call to
+ *     wimax_dev_add().
+ *     It is recommended that the driver leaves this state when
+ *     calling 'ifconfig DEV up' and enters it back on 'ifconfig DEV
+ *     down'.
+ *
+ * @__WIMAX_ST_QUIESCING: The device is being torn down, so no API
+ *     operations are allowed to proceed except the ones needed to
+ *     complete the device clean up process.
+ *
+ * @WIMAX_ST_UNINITIALIZED: [optional] Communication with the device
+ *     is setup, but the device still requires some configuration
+ *     before being operational.
+ *     Some WiMAX API calls might work.
+ *
+ * @WIMAX_ST_RADIO_OFF: The device is fully up; radio is off (wether
+ *     by hardware or software switches).
+ *     It is recommended to always leave the device in this state
+ *     after initialization.
+ *
+ * @WIMAX_ST_READY: The device is fully up and radio is on.
+ *
+ * @WIMAX_ST_SCANNING: [optional] The device has been instructed to
+ *     scan. In this state, the device cannot be actively connected to
+ *     a network.
+ *
+ * @WIMAX_ST_CONNECTING: The device is connecting to a network. This
+ *     state exists because in some devices, the connect process can
+ *     include a number of negotiations between user space, kernel
+ *     space and the device. User space needs to know what the device
+ *     is doing. If the connect sequence in a device is atomic and
+ *     fast, the device can transition directly to CONNECTED
+ *
+ * @WIMAX_ST_CONNECTED: The device is connected to a network.
+ *
+ * @__WIMAX_ST_INVALID: This is an invalid state used to mark the
+ *     maximum numeric value of states.
+ *
+ * Description:
+ *
+ * Transitions from one state to another one are atomic and can only
+ * be caused in kernel space with wimax_state_change(). To read the
+ * state, use wimax_state_get().
+ *
+ * States starting with __ are internal and shall not be used or
+ * referred to by drivers or userspace. They look ugly, but that's the
+ * point -- if any use is made non-internal to the stack, it is easier
+ * to catch on review.
+ *
+ * All API operations [with well defined exceptions] will take the
+ * device mutex before starting and then check the state. If the state
+ * is %__WIMAX_ST_NULL, %WIMAX_ST_DOWN, %WIMAX_ST_UNINITIALIZED or
+ * %__WIMAX_ST_QUIESCING, it will drop the lock and quit with
+ * -%EINVAL, -%ENOMEDIUM, -%ENOTCONN or -%ESHUTDOWN.
+ *
+ * The order of the definitions is important, so we can do numerical
+ * comparisons (eg: < %WIMAX_ST_RADIO_OFF means the device is not ready
+ * to operate).
+ */
+/*

+ *  - Initial implementation
+ *
+ *
+ * This header defines the data structures and constants used to
+ * communicate with the device.
+ *
+ * BOOTMODE/BOOTROM/FIRMWARE UPLOAD PROTOCOL
+ *
+ * The firmware upload protocol is quite simple and only requires a
+ * handful of commands. See drivers/net/wimax/i2400m/fw.c for more
+ * details.
+ *
+ * The BCF data structure is for the firmware file header.
+ *
+ *
+ * THE DATA / CONTROL PROTOCOL
+ *
+ * This is the normal protocol spoken with the device once the
+ * firmware is uploaded. It transports data payloads and control
+ * messages back and forth.
+ *
+ * It consists 'messages' that pack one or more payloads each. The
+ * format is described in detail in drivers/net/wimax/i2400m/rx.c and
+ * tx.c.
+ *
+ *
+ * THE L3L4 PROTOCOL
+ *
+ * The term L3L4 refers to Layer 3 (the device), Layer 4 (the
+ * driver/host software).
+ *
+ * This is the control protocol used by the host to control the i2400m
+ * device (scan, connect, disconnect...). This is sent to / received
+ * as control frames. These frames consist of a header and zero or
+ * more TLVs with information. We call each control frame a "message".
+ *
+ * Each message is composed of:
+ *
+ * HEADER
+ * [TLV0 + PAYLOAD0]
+ * [TLV1 + PAYLOAD1]
+ * [...]
+ * [TLVN + PAYLOADN]
+ *
+ * The HEADER is defined by 'struct i2400m_l3l4_hdr'. The payloads are
+ * defined by a TLV structure (Type Length Value) which is a 'header'
+ * (struct i2400m_tlv_hdr) and then the payload.
+ *
+ * All integers are represented as Little Endian.
+ *
+ * - REQUESTS AND EVENTS
+ *
+ * The requests can be clasified as follows:
+ *
+ *   COMMAND:  implies a request from the host to the device requesting
+ *             an action being performed. The device will reply with a
+ *             message (with the same type as the command), status and
+ *             no (TLV) payload. Execution of a command might cause
+ *             events (of different type) to be sent later on as
+ *             device's state changes.
+ *
+ *   GET/SET:  similar to COMMAND, but will not cause other
+ *             EVENTs. The reply, in the case of GET, will contain
+ *             TLVs with the requested information.
+ *
+ *   EVENT:    asynchronous messages sent from the device, maybe as a
+ *             consequence of previous COMMANDs but disassociated from
+ *             them.
+ *
+ * Only one request might be pending at the same time (ie: don't
+ * parallelize nor post another GET request before the previous
+ * COMMAND has been acknowledged with it's corresponding reply by the
+ * device).
+ *
+ * The different requests and their formats are described below:
+ *
+ *  I2400M_MT_*   Message types
+ *  I2400M_MS_*   Message status (for replies, events)
+ *  i2400m_tlv_*  TLVs
+ *
+ * data types are named 'struct i2400m_msg_OPNAME', OPNAME matching the
+ * operation.

+/************************** DOCUMENTATION **************************/
+/*
+ * Initial APIs (1996 -> onward) :
+ * -----------------------------
+ * Basically, the wireless extensions are for now a set of standard ioctl
+ * call + /proc/net/wireless
+ *
+ * The entry /proc/net/wireless give statistics and information on the
+ * driver.
+ * This is better than having each driver having its entry because
+ * its centralised and we may remove the driver module safely.
+ *
+ * Ioctl are used to configure the driver and issue commands.  This is
+ * better than command line options of insmod because we may want to
+ * change dynamically (while the driver is running) some parameters.
+ *
+ * The ioctl mechanimsm are copied from standard devices ioctl.
+ * We have the list of command plus a structure descibing the
+ * data exchanged...
+ * Note that to add these ioctl, I was obliged to modify :
+ *	# net/core/dev.c (two place + add include)
+ *	# net/ipv4/af_inet.c (one place + add include)
+ *
+ * /proc/net/wireless is a copy of /proc/net/dev.
+ * We have a structure for data passed from the driver to /proc/net/wireless
+ * Too add this, I've modified :
+ *	# net/core/dev.c (two other places)
+ *	# include/linux/netdevice.h (one place)
+ *	# include/linux/proc_fs.h (one place)
+ *
+ * New driver API (2002 -> onward) :
+ * -------------------------------
+ * This file is only concerned with the user space API and common definitions.
+ * The new driver API is defined and documented in :
+ *	# include/net/iw_handler.h
+ *
+ * Note as well that /proc/net/wireless implementation has now moved in :
+ *	# net/core/wireless.c
+ *
+ * Wireless Events (2002 -> onward) :
+ * --------------------------------
+ * Events are defined at the end of this file, and implemented in :
+ *	# net/core/wireless.c
+ *
+ * Other comments :
+ * --------------
+ * Do not add here things that are redundant with other mechanisms
+ * (drivers init, ifconfig, /proc/net/dev, ...) and with are not
+ * wireless specific.
+ *
+ * These wireless extensions are not magic : each driver has to provide
+ * support for them...
+ *
+ * IMPORTANT NOTE : As everything in the kernel, this is very much a
+ * work in progress. Contact me if you have ideas of improvements...

+ * MTD devices may be attached using %UBI_IOCATT ioctl command of the UBI
+ * control device. The caller has to properly fill and pass
+ * &struct ubi_attach_req object - UBI will attach the MTD device specified in
+ * the request and return the newly created UBI device number as the ioctl
+ * return value.
+ *
+ * UBI device deletion (the same as MTD device detachment)
+ * ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+ *
+ * An UBI device maybe deleted with %UBI_IOCDET ioctl command of the UBI
+ * control device.
+ *
+ * UBI volume creation
+ * ~~~~~~~~~~~~~~~~~~~
+ *
+ * UBI volumes are created via the %UBI_IOCMKVOL ioctl command of UBI character
+ * device. A &struct ubi_mkvol_req object has to be properly filled and a
+ * pointer to it has to be passed to the ioctl.
+ *
+ * UBI volume deletion
+ * ~~~~~~~~~~~~~~~~~~~
+ *
+ * To delete a volume, the %UBI_IOCRMVOL ioctl command of the UBI character
+ * device should be used. A pointer to the 32-bit volume ID hast to be passed
+ * to the ioctl.
+ *
+ * UBI volume re-size
+ * ~~~~~~~~~~~~~~~~~~
+ *
+ * To re-size a volume, the %UBI_IOCRSVOL ioctl command of the UBI character
+ * device should be used. A &struct ubi_rsvol_req object has to be properly
+ * filled and a pointer to it has to be passed to the ioctl.
+ *
+ * UBI volumes re-name
+ * ~~~~~~~~~~~~~~~~~~~
+ *
+ * To re-name several volumes atomically at one go, the %UBI_IOCRNVOL command
+ * of the UBI character device should be used. A &struct ubi_rnvol_req object
+ * has to be properly filled and a pointer to it has to be passed to the ioctl.
+ *
+ * UBI volume update
+ * ~~~~~~~~~~~~~~~~~
+ *
+ * Volume update should be done via the %UBI_IOCVOLUP ioctl command of the
+ * corresponding UBI volume character device. A pointer to a 64-bit update
+ * size should be passed to the ioctl. After this, UBI expects user to write
+ * this number of bytes to the volume character device. The update is finished
+ * when the claimed number of bytes is passed. So, the volume update sequence
+ * is something like:
+ *
+ * fd = open("/dev/my_volume");
+ * ioctl(fd, UBI_IOCVOLUP, &image_size);
+ * write(fd, buf, image_size);
+ * close(fd);
+ *
+ * Logical eraseblock erase
+ * ~~~~~~~~~~~~~~~~~~~~~~~~
+ *
+ * To erase a logical eraseblock, the %UBI_IOCEBER ioctl command of the
+ * corresponding UBI volume character device should be used. This command
+ * unmaps the requested logical eraseblock, makes sure the corresponding
+ * physical eraseblock is successfully erased, and returns.
+ *
+ * Atomic logical eraseblock change
+ * ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+ *
+ * Atomic logical eraseblock change operation is called using the %UBI_IOCEBCH
+ * ioctl command of the corresponding UBI volume character device. A pointer to
+ * a &struct ubi_leb_change_req object has to be passed to the ioctl. Then the
+ * user is expected to write the requested amount of bytes (similarly to what
+ * should be done in case of the "volume update" ioctl).
+ *
+ * Logical eraseblock map
+ * ~~~~~~~~~~~~~~~~~~~~~
+ *
+ * To map a logical eraseblock to a physical eraseblock, the %UBI_IOCEBMAP
+ * ioctl command should be used. A pointer to a &struct ubi_map_req object is
+ * expected to be passed. The ioctl maps the requested logical eraseblock to
+ * a physical eraseblock and returns.  Only non-mapped logical eraseblocks can
+ * be mapped. If the logical eraseblock specified in the request is already
+ * mapped to a physical eraseblock, the ioctl fails and returns error.
+ *
+ * Logical eraseblock unmap
+ * ~~~~~~~~~~~~~~~~~~~~~~~~
+ *
+ * To unmap a logical eraseblock to a physical eraseblock, the %UBI_IOCEBUNMAP
+ * ioctl command should be used. The ioctl unmaps the logical eraseblocks,
+ * schedules corresponding physical eraseblock for erasure, and returns. Unlike
+ * the "LEB erase" command, it does not wait for the physical eraseblock being
+ * erased. Note, the side effect of this is that if an unclean reboot happens
+ * after the unmap ioctl returns, you may find the LEB mapped again to the same
+ * physical eraseblock after the UBI is run again.
+ *
+ * Check if logical eraseblock is mapped
+ * ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+ *
+ * To check if a logical eraseblock is mapped to a physical eraseblock, the
+ * %UBI_IOCEBISMAP ioctl command should be used. It returns %0 if the LEB is
+ * not mapped, and %1 if it is mapped.
+ *
+ * Set an UBI volume property
+ * ~~~~~~~~~~~~~~~~~~~~~~~~~
+ *
+ * To set an UBI volume property the %UBI_IOCSETPROP ioctl command should be
+ * used. A pointer to a &struct ubi_set_vol_prop_req object is expected to be
+ * passed. The object describes which property should be set, and to which value
+ * it should be set.
+ *
+ * Block devices on UBI volumes
+ * ~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+ *
+ * To create a R/O block device on top of an UBI volume the %UBI_IOCVOLCRBLK
+ * should be used. A pointer to a &struct ubi_blkcreate_req object is expected
+ * to be passed, which is not used and reserved for future usage.
+ *
+ * Conversely, to remove a block device the %UBI_IOCVOLRMBLK should be used,
+ * which takes no arguments.

+ * @max_beb_per1024: maximum expected number of bad PEB per 1024 PEBs
+ * @padding: reserved for future, not used, has to be zeroed
+ *
+ * This data structure is used to specify MTD device UBI has to attach and the
+ * parameters it has to use. The number which should be assigned to the new UBI
+ * device is passed in @ubi_num. UBI may automatically assign the number if
+ * @UBI_DEV_NUM_AUTO is passed. In this case, the device number is returned in
+ * @ubi_num.
+ *
+ * Most applications should pass %0 in @vid_hdr_offset to make UBI use default
+ * offset of the VID header within physical eraseblocks. The default offset is
+ * the next min. I/O unit after the EC header. For example, it will be offset
+ * 512 in case of a 512 bytes page NAND flash with no sub-page support. Or
+ * it will be 512 in case of a 2KiB page NAND flash with 4 512-byte sub-pages.
+ *
+ * But in rare cases, if this optimizes things, the VID header may be placed to
+ * a different offset. For example, the boot-loader might do things faster if
+ * the VID header sits at the end of the first 2KiB NAND page with 4 sub-pages.
+ * As the boot-loader would not normally need to read EC headers (unless it
+ * needs UBI in RW mode), it might be faster to calculate ECC. This is weird
+ * example, but it real-life example. So, in this example, @vid_hdr_offer would
+ * be 2KiB-64 bytes = 1984. Note, that this position is not even 512-bytes
+ * aligned, which is OK, as UBI is clever enough to realize this is 4th
+ * sub-page of the first page and add needed padding.
+ *
+ * The @max_beb_per1024 is the maximum amount of bad PEBs UBI expects on the
+ * UBI device per 1024 eraseblocks.  This value is often given in an other form
+ * in the NAND datasheet (min NVB i.e. minimal number of valid blocks). The
+ * maximum expected bad eraseblocks per 1024 is then:
+ *    1024 * (1 - MinNVB / MaxNVB)
+ * Which gives 20 for most NAND devices.  This limit is used in order to derive
+ * amount of eraseblock UBI reserves for handling new bad blocks. If the device
+ * has more bad eraseblocks than this limit, UBI does not reserve any physical
+ * eraseblocks for new bad eraseblocks, but attempts to use available
+ * eraseblocks (if any). The accepted range is 0-768. If 0 is given, the
+ * default kernel value of %CONFIG_MTD_UBI_BEB_LIMIT will be used.

+ *	read packet(or write "set_tear_on" command) and BTA request.
+ *	after transmitting read packet or write "set_tear_on" command,

+
+/* Some rough guidelines on accessing and updating grant-table entries
+ * in a concurrency-safe manner. For more information, Linux contains a
+ * reference implementation for guest OSes (arch/xen/kernel/grant_table.c).
+ *
+ * NB. WMB is a no-op on current-generation x86 processors. However, a
+ *     compiler barrier will still be required.
+ *
+ * Introducing a valid entry into the grant table:
+ *  1. Write ent->domid.
+ *  2. Write ent->frame:
+ *      GTF_permit_access:   Frame to which access is permitted.
+ *      GTF_accept_transfer: Pseudo-phys frame slot being filled by new
+ *                           frame, or zero if none.
+ *  3. Write memory barrier (WMB).
+ *  4. Write ent->flags, inc. valid type.
+ *
+ * Invalidating an unused GTF_permit_access entry:
+ *  1. flags = ent->flags.
+ *  2. Observe that !(flags & (GTF_reading|GTF_writing)).
+ *  3. Check result of SMP-safe CMPXCHG(&ent->flags, flags, 0).
+ *  NB. No need for WMB as reuse of entry is control-dependent on success of
+ *      step 3, and all architectures guarantee ordering of ctrl-dep writes.
+ *
+ * Invalidating an in-use GTF_permit_access entry:
+ *  This cannot be done directly. Request assistance from the domain controller
+ *  which can set a timeout on the use of a grant entry and take necessary
+ *  action. (NB. This is not yet implemented!).
+ *
+ * Invalidating an unused GTF_accept_transfer entry:
+ *  1. flags = ent->flags.
+ *  2. Observe that !(flags & GTF_transfer_committed). [*]
+ *  3. Check result of SMP-safe CMPXCHG(&ent->flags, flags, 0).
+ *  NB. No need for WMB as reuse of entry is control-dependent on success of
+ *      step 3, and all architectures guarantee ordering of ctrl-dep writes.
+ *  [*] If GTF_transfer_committed is set then the grant entry is 'committed'.
+ *      The guest must /not/ modify the grant entry until the address of the
+ *      transferred frame is written. It is safe for the guest to spin waiting
+ *      for this to occur (detect by observing GTF_transfer_completed in
+ *      ent->flags).
+ *
+ * Invalidating a committed GTF_accept_transfer entry:
+ *  1. Wait for (ent->flags & GTF_transfer_completed).
+ *
+ * Changing a GTF_permit_access from writable to read-only:
+ *  Use SMP-safe CMPXCHG to set GTF_readonly, while checking !GTF_writing.
+ *
+ * Changing a GTF_permit_access from read-only to writable:

+ * 'discard-alignment' - Devices that support discard functionality may

+ * logical block size. The discard-alignment parameter indicates how many bytes
+ * the beginning of the partition is offset from the internal allocation unit's
+ * natural alignment.
+ * 'discard-granularity'  - Devices that support discard functionality may
+ * internally allocate space using units that are bigger than the logical block
+ * size. The discard-granularity parameter indicates the size of the internal
+ * allocation unit in bytes if reported by the device. Otherwise the
+ * discard-granularity will be set to match the device's physical block size.
+ * 'discard-secure' - All copies of the discarded sectors (potentially created
+ * by garbage collection) must also be erased.  To use this feature, the flag

+ * To make use of this feature, frontend should allocate two event
+ * channels for TX and RX, advertise them to backend as
+ * "event-channel-tx" and "event-channel-rx" respectively. If frontend
+ * doesn't want to use this feature, it just writes "event-channel"
+ * node as before.
+ */
+
+/*
+ * Multiple transmit and receive queues:
+ * If supported, the backend will write the key "multi-queue-max-queues" to
+ * the directory for that vif, and set its value to the maximum supported
+ * number of queues.
+ * Frontends that are aware of this feature and wish to use it can write the
+ * key "multi-queue-num-queues", set to the number they wish to use, which
+ * must be greater than zero, and no more than the value reported by the backend
+ * in "multi-queue-max-queues".
+ *
+ * Queues replicate the shared rings and event channels.
+ * "feature-split-event-channels" may optionally be used when using
+ * multiple queues, but is not mandatory.
+ *
+ * Each queue consists of one shared ring pair, i.e. there must be the same
+ * number of tx and rx rings.
+ *
+ * For frontends requesting just one queue, the usual event-channel and
+ * ring-ref keys are written as before, simplifying the backend processing
+ * to avoid distinguishing between a frontend that doesn't understand the
+ * multi-queue feature, and one that does, but requested only one queue.
+ *
+ * Frontends requesting two or more queues must not write the toplevel
+ * event-channel (or event-channel-{tx,rx}) and {tx,rx}-ring-ref keys,
+ * instead writing those keys under sub-keys having the name "queue-N" where
+ * N is the integer ID of the queue for which those keys belong. Queues
+ * are indexed from zero. For example, a frontend with two queues and split
+ * event channels must write the following set of queue-related keys:
+ *
+ * /local/domain/1/device/vif/0/multi-queue-num-queues = "2"
+ * /local/domain/1/device/vif/0/queue-0 = ""
+ * /local/domain/1/device/vif/0/queue-0/tx-ring-ref = "<ring-ref-tx0>"
+ * /local/domain/1/device/vif/0/queue-0/rx-ring-ref = "<ring-ref-rx0>"
+ * /local/domain/1/device/vif/0/queue-0/event-channel-tx = "<evtchn-tx0>"
+ * /local/domain/1/device/vif/0/queue-0/event-channel-rx = "<evtchn-rx0>"
+ * /local/domain/1/device/vif/0/queue-1 = ""
+ * /local/domain/1/device/vif/0/queue-1/tx-ring-ref = "<ring-ref-tx1>"
+ * /local/domain/1/device/vif/0/queue-1/rx-ring-ref = "<ring-ref-rx1"
+ * /local/domain/1/device/vif/0/queue-1/event-channel-tx = "<evtchn-tx1>"
+ * /local/domain/1/device/vif/0/queue-1/event-channel-rx = "<evtchn-rx1>"
+ *
+ * If there is any inconsistency in the XenStore data, the backend may
+ * choose not to connect any queues, instead treating the request as an
+ * error. This includes scenarios where more (or fewer) queues were
+ * requested than the frontend provided details for.
+ *
+ * Mapping of packets to queues is considered to be a function of the
+ * transmitting system (backend or frontend) and is not negotiated
+ * between the two. Guests are free to transmit packets on any queue

+ * Any specified default value is in effect if the corresponding XenBus node
+ * is not present in the XenStore.

+ *                                         unsigned foreigndom)
+ * @reqs is an array of mmu_update_t structures ((ptr, val) pairs).
+ * @count is the length of the above array.
+ * @pdone is an output parameter indicating number of completed operations
+ * @foreigndom[15:0]: FD, the expected owner of data pages referenced in this
+ *                    hypercall invocation. Can be DOMID_SELF.
+ * @foreigndom[31:16]: PFD, the expected owner of pagetable pages referenced
+ *                     in this hypercall invocation. The value of this field
+ *                     (x) encodes the PFD as follows:
+ *                     x == 0 => PFD == DOMID_SELF
+ *                     x != 0 => PFD == x - 1
+ *
+ * Sub-commands: ptr[1:0] specifies the appropriate MMU_* command.
+ * -------------
+ * ptr[1:0] == MMU_NORMAL_PT_UPDATE:
+ * Updates an entry in a page table belonging to PFD. If updating an L1 table,
+ * and the new table entry is valid/present, the mapped frame must belong to
+ * FD. If attempting to map an I/O page then the caller assumes the privilege
+ * of the FD.
+ * FD == DOMID_IO: Permit /only/ I/O mappings, at the priv level of the caller.
+ * FD == DOMID_XEN: Map restricted areas of Xen's heap space.
+ * ptr[:2]  -- Machine address of the page-table entry to modify.
+ * val      -- Value to write.
+ *
+ * There also certain implicit requirements when using this hypercall. The
+ * pages that make up a pagetable must be mapped read-only in the guest.
+ * This prevents uncontrolled guest updates to the pagetable. Xen strictly
+ * enforces this, and will disallow any pagetable update which will end up
+ * mapping pagetable page RW, and will disallow using any writable page as a
+ * pagetable. In practice it means that when constructing a page table for a
+ * process, thread, etc, we MUST be very dilligient in following these rules:
+ *  1). Start with top-level page (PGD or in Xen language: L4). Fill out
+ *      the entries.
+ *  2). Keep on going, filling out the upper (PUD or L3), and middle (PMD
+ *      or L2).
+ *  3). Start filling out the PTE table (L1) with the PTE entries. Once
+ *      done, make sure to set each of those entries to RO (so writeable bit
+ *      is unset). Once that has been completed, set the PMD (L2) for this
+ *      PTE table as RO.
+ *  4). When completed with all of the PMD (L2) entries, and all of them have
+ *      been set to RO, make sure to set RO the PUD (L3). Do the same
+ *      operation on PGD (L4) pagetable entries that have a PUD (L3) entry.
+ *  5). Now before you can use those pages (so setting the cr3), you MUST also
+ *      pin them so that the hypervisor can verify the entries. This is done
+ *      via the HYPERVISOR_mmuext_op(MMUEXT_PIN_L4_TABLE, guest physical frame
+ *      number of the PGD (L4)). And this point the HYPERVISOR_mmuext_op(
+ *      MMUEXT_NEW_BASEPTR, guest physical frame number of the PGD (L4)) can be
+ *      issued.
+ * For 32-bit guests, the L4 is not used (as there is less pagetables), so
+ * instead use L3.
+ * At this point the pagetables can be modified using the MMU_NORMAL_PT_UPDATE
+ * hypercall. Also if so desired the OS can also try to write to the PTE
+ * and be trapped by the hypervisor (as the PTE entry is RO).
+ *
+ * To deallocate the pages, the operations are the reverse of the steps
+ * mentioned above. The argument is MMUEXT_UNPIN_TABLE for all levels and the
+ * pagetable MUST not be in use (meaning that the cr3 is not set to it).
+ *
+ * ptr[1:0] == MMU_MACHPHYS_UPDATE:
+ * Updates an entry in the machine->pseudo-physical mapping table.
+ * ptr[:2]  -- Machine address within the frame whose mapping to modify.
+ *             The frame must belong to the FD, if one is specified.
+ * val      -- Value to write into the mapping entry.
+ *
+ * ptr[1:0] == MMU_PT_UPDATE_PRESERVE_AD:
+ * As MMU_NORMAL_PT_UPDATE above, but A/D bits currently in the PTE are ORed
+ * with those in @val.
+ *
+ * @val is usually the machine frame number along with some attributes.
+ * The attributes by default follow the architecture defined bits. Meaning that
+ * if this is a X86_64 machine and four page table layout is used, the layout
+ * of val is:
+ *  - 63 if set means No execute (NX)
+ *  - 46-13 the machine frame number
+ *  - 12 available for guest
+ *  - 11 available for guest
+ *  - 10 available for guest
+ *  - 9 available for guest
+ *  - 8 global
+ *  - 7 PAT (PSE is disabled, must use hypercall to make 4MB or 2MB pages)
+ *  - 6 dirty
+ *  - 5 accessed
+ *  - 4 page cached disabled
+ *  - 3 page write through
+ *  - 2 userspace accessible
+ *  - 1 writeable
+ *  - 0 present
+ *
+ *  The one bits that does not fit with the default layout is the PAGE_PSE
+ *  also called PAGE_PAT). The MMUEXT_[UN]MARK_SUPER arguments to the
+ *  HYPERVISOR_mmuext_op serve as mechanism to set a pagetable to be 4MB
+ *  (or 2MB) instead of using the PAGE_PSE bit.
+ *
+ *  The reason that the PAGE_PSE (bit 7) is not being utilized is due to Xen
+ *  using it as the Page Attribute Table (PAT) bit - for details on it please
+ *  refer to Intel SDM 10.12. The PAT allows to set the caching attributes of
+ *  pages instead of using MTRRs.
+ *
+ *  The PAT MSR is as follows (it is a 64-bit value, each entry is 8 bits):
+ *                    PAT4                 PAT0
+ *  +-----+-----+----+----+----+-----+----+----+
+ *  | UC  | UC- | WC | WB | UC | UC- | WC | WB |  <= Linux
+ *  +-----+-----+----+----+----+-----+----+----+
+ *  | UC  | UC- | WT | WB | UC | UC- | WT | WB |  <= BIOS (default when machine boots)
+ *  +-----+-----+----+----+----+-----+----+----+
+ *  | rsv | rsv | WP | WC | UC | UC- | WT | WB |  <= Xen
+ *  +-----+-----+----+----+----+-----+----+----+
+ *
+ *  The lookup of this index table translates to looking up
+ *  Bit 7, Bit 4, and Bit 3 of val entry:
+ *
+ *  PAT/PSE (bit 7) ... PCD (bit 4) .. PWT (bit 3).
+ *
+ *  If all bits are off, then we are using PAT0. If bit 3 turned on,
+ *  then we are using PAT1, if bit 3 and bit 4, then PAT2..
+ *
+ *  As you can see, the Linux PAT1 translates to PAT4 under Xen. Which means
+ *  that if a guest that follows Linux's PAT setup and would like to set Write
+ *  Combined on pages it MUST use PAT4 entry. Meaning that Bit 7 (PAGE_PAT) is
+ *  set. For example, under Linux it only uses PAT0, PAT1, and PAT2 for the
+ *  caching as:
+ *
+ *   WB = none (so PAT0)
+ *   WC = PWT (bit 3 on)
+ *   UC = PWT | PCD (bit 3 and 4 are on).
+ *
+ * To make it work with Xen, it needs to translate the WC bit as so:
+ *
+ *  PWT (so bit 3 on) --> PAT (so bit 7 is on) and clear bit 3
+ *
+ * And to translate back it would:
+ *
+ * PAT (bit 7 on) --> PWT (bit 3 on) and clear bit 7.

+	 *  2. The main purpose of the per-VCPU mask is therefore to restrict
+	 *     reentrant execution: whether for concurrency control, or to
+	 *     prevent unbounded stack usage. Whatever the purpose, we expect
+	 *     that the mask will be asserted only for short periods at a time,
+	 *     and so the likelihood of a 'spurious' IPI is suitably small.
+	 * The mask is read before making an event upcall to the guest: a
+	 * non-zero mask therefore guarantees that the VCPU will not receive
+	 * an upcall activation. The mask is cleared when the VCPU requests
+	 * to block: this avoids wakeup-waiting races.

+	 *     arrange out-of-band to set up a connection (usually by allocating
+	 *     an unbound 'listener' port and avertising that via a storage service
+	 *     such as xenstore).
+	 *  2. Physical interrupts. A domain with suitable hardware-access
+	 *     privileges can bind an event-channel port to a physical interrupt
+	 *     source.
+	 *  3. Virtual interrupts ('events'). A domain can bind an event-channel
+	 *     port to a virtual interrupt source, such as the virtual-timer
+	 *     device or the emergency console.
+	 *
+	 * Event channels are addressed by a "port index". Each channel is
+	 * associated with two bits of information:
+	 *  1. PENDING -- notifies the domain that there is a pending notification
+	 *     to be processed. This bit is cleared by the guest.
+	 *  2. MASK -- if this bit is clear then a 0->1 transition of PENDING
+	 *     will cause an asynchronous upcall to be scheduled. This bit is only
+	 *     updated by the guest. It is read-only within Xen. If a channel
+	 *     becomes pending while the channel is masked then the 'edge' is lost
+	 *     (i.e., when the channel is unmasked, the guest must manually handle
+	 *     pending notifications as no upcall will be scheduled by Xen).
+	 *
+	 * To expedite scanning of pending notifications, any 0->1 pending
+	 * transition on an unmasked channel causes a corresponding bit in a
+	 * per-vcpu selector word to be set. Each bit in the selector covers a
+	 * 'C long' in the PENDING bitfield array.

+ *  8. All bootstrap elements are mapped read-writable for the guest OS. The
+ *     only exception is the bootstrap page table, which is mapped read-only.
