mbuf size was setup to achieve the best performance i.e.
using the smallest mbuf and not segmenting packets.
However this resulted in complex code, much dependent of the way
the pmd are working e.g. a change(fix) in recent dpdk i40e
implementation caused a 1782 (=1518+8+256) bytes mbuf to be too
small to hold a 1518 bytes packets.
Hence this change simplifies the mbuf size selection at the price
of a potential decreases in performance - as more memory is now used.
Except if jumbo frames are used, the mbuf size will now be the same
for all modes. The packets will not be segmented except if jumbo
frames are enabled.
If jumbo frames are enabled, packets are by default segmented, except
if the mbuf size is configured big enough in the config file.

When configuring a port, prox configures queue flags.
For historitical reasons, offloads had to be disabled on
some pmds.
There is now an API to query the ports and gets their
capabilities. This fix sets now the flags based on the capabilities,
and not the driver name.

Add support for pkt_inline of jumbo frames.
Dump the whole packet, and not a truncated packet. This might
have a small impact on performance as the memory footprint
is increased (by ~640K * number of tasks), resulting in potential
higher DTLB misses.

In the [core] definition we were able to use one variable
such as $core1 in [core $core1] but not [core ${core1}].
The second syntax is used when we want multiple
variables such as in [core ${first_core}-${last_core}].
This second syntax is now supported.

When link is down at startup, the link_speed returned by DPDK
is 0. This results in un-optimized latency estimates in gen and lat.
With this fix, lat and gen do nothing until link_speed is
properly initialized, and use the right link speed in the fast path.

Jumbo frames are now supported through the addition of a "mtu"
parameter of the port in the config file.
Setting the mtu to a value higher than 1500 bytes will enable
the reception of jumbo frames.
In addition, the rte_eth_dev_set_mtu is now set for all pmds.
Finally, setting mbuf_size does not set MEMPOOL_F_NO_SPREAD
anymore. This option was only used for pure debugging.
Big packets can be received using two ways
- Using multiple "small" mbufs, i.e. around 2K. This is the default.
- Using one big mbuf holding the whole packet. This can be enabled
by setting a parameter mbuf_size in the receiving core configuration

This file describes flavors, flavor meta data and boot info.
All this info can be defined in the [Default] section and will then be
used by to create all VMs. This data can also be specified in individual
VM sections to overule the deault values per VM.

Revert back part of commit 9fa316261d7d9
The function abs_diff was erroneously changed to diff_or_zero.
This function was supposed to measure the difference between rx and
tx time; when rx time overflowed and tx time not yet (i.e.
rx time ~= 0 and tx_time ~=UINT32_MAX, this function added UINT32_MAX
to rx_time. The name of the function was confusing and caused the
previous commit. Net effect of previous commit was that every four seconds
the minimum latency was 0
This commit reverse back to the original behavior, with a function name
diff_time.

Link_speed could be null when prox started with the ports down.
This was potentially causing a crash.
Another task will need to update link speed when the port come
up. Failing to do this results in less accurate latencies
(no extrapolation)

* Calculation of aboslute and relative dropped packets was wrong and is
now fixed.
* ./createrapid.py has now an extra option to select custom availability
zones for the different VMs.
* Fixed a typo to create the flavor: hw:cpu_thread_policy
* The generator config files have now the packet id & signature fields.
See PROX for more details on this.
* ./runrapid has now a new option --configonly. Default is False. If set
to True, all configuration files will be copied to the VMS, but the
tests are not started. This allows you to go to the VMs and manually
start PROX.
* In addition to the average latency, maximum latency is now also
displayed.

- Also changed lat_info.tx_packet_index to uint64_t,
so also did it for task_lat.prev_tx_packet_index and n_loss.
- Adjusted format strings accordingly, and fixed some other formats.
- Adjusted overflow increment to 2^32 (i.e. UINT32_MAX + 1).
- Replaced hard-coded 64 with ACCURACY_BUFFER_SIZE (still hard-coded
in handle_gen.c).

This feature will enable the possibility to have many cores
configured in a prox config file, and enable/disable them
through variables.
For instance, a [core $var1] section in a config file will
result in [core 1] if $var1 = 1; the whole section and section
content will be ignored if $var1=#
Before this implementation, [#core 1] or [core #] was already
treated as a commented out section (the whole section was
commented). But there was no way to define a variable $var = #
to comment a section through a variable.
Note that in today's implementation any non numerical
(except s, h, t, -) characteter in the [core] section header
(and not only #) will cause the section to be ignored.
It would probably be better to consider # (as maybe N/A and none)
as comments, and everything else as error. This is however not
supported by the change request.

Using l2 testing, where no ARP messages are being used, you can now run
a zero packet loss test. The binary search will continue to find the
speed where absolutely no packets have been lost during the test.
On top of that, the output has been reformatted to also show the
absolute and relative packet loss.
The *.test files have now 2 new parameters: drop_rate_treshold and accuracy.
When drop_rate_treshold is set to 0, this test will conclude successfull
when no packet has been lost whatsoever. If this is set to any other
number, the test will be successfull when the relative packet loss is
lower than drop_rate_treshold.
The new accuray parameter defines when the binary search will stop:
when the relative difference between the min and max of the search
window is lower than accuracy.
The irq testing is slightly modified to print the total number of
interrupts in a certain time bucket, not only as the number per second,
but when there is no interrupt whatsowever, we print '0' in stead of
'0.0'

When doing latency measurements PROX takes into account the
generation or reception of a bulk of packets. For instance, if
PROX receives at time T 4 packets, it knows that the first
packet was received by te NIC before T (the time to receive the other
3 packets, as they were received at maximum link speed).
So the latency data is decreased by the minimum time to receive those
3 packets.
For this PROX was using a default link speed of 10Gbps. This is wrong
for 1Gbps and 40Gbps networks, and was causing for instance issues
on 40 Gbps networks as extrapolating too much, resulting in either
too low latencies or negative numbers (visible as very high latencies).

irq mode can be used to show how a core is interrupted by other tasks.
This mode does not handle packets. It only loops reading tsc.
When the difference between two consecutive calls to rdtsc() is high
then it means the core was interrupted.
This task implementes the display, so that we can see a histogram of
interrupts as well as the maximum, per core.
Command line is also supported, through "show irq buckets" (too show
the intervals of each buckets, in micrcoseconds), and the stats
command line (showing the number of items in each buckets and the max)..

There were two issues identified in dump receive packets
- when the receive packets was going to be dropped (and not transmitted),
it was also printed as TX[255].
- a potential crash when using the dump function with modes like
lat which can receive more than MAX_RING_BURST.
Those issues have been fixed.
