In some (rare) modes, more than 64 packets can be received through
one rx function. This is for instance the case of the lat mode.

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'

Fixed issues with pkt_size. For a 64 byte packet, we need to issue
pkt_size <core> <task> 60
4 extra bytes will be calculated and added automatically by PROX
Also added the missing irq.test and irq.cfg files
Added support for OpenStack systems not using floating IP addresses

Cores can now be specified in the test files. An irq test has been
added to verify if the VMs are not suffering from long interrupts.

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.

When doing latency measurements the generator can add a
32 bits signature in the packet at a specific location,
so that the receiver only uses the packets generated by the
generator and ignores packets generated for instance by a switch
The is particuly important for latency measurements as we use
data in the packets as timestamps, and packets generated elsewhere
would result in random latency for those packets.

PROX can stack different RX functions, so that they are executed
after each other.
This feature is for instance used to dump packets or to print
distribution of receive packets, without influencing the performance
of the rx functions when no dump or print is needed.
The previous implementation was wrong and causing some of the stacked
functions not to be executed. This was causing for instance issues
in latency measurement after enabling dumping packets.

L2fwd and swap has many options to set src mac. swap was supposed
to support the ability to use port mac, but config file parsing was
wrong. L2fwd was using port mac if a port was available and if
src mac=packet or if there was no src mac in the config.
Now l2fwd supports the following options
- "src mac=xx:xx:xx:xx:xx:xx" => this mac address is used as src mac.
- "src mac=packet" => the src mac is taken from the dst mac of the
received packet.
- "src mac=hw" => the src mac is taken from the mac address of the port,
if there is a physical port. Error otherwise.
- "src mac=no" => src mac kept untouched
- No "src mac" => same as "src mac=hw" if there is a physical port
and same as "src mac=packet" otherwise.
Default is (no "src mac") hence the mac is taken from the tx port if there
is one tx port and from the packet otherwise.
swap support is similar, except that it does not support "src mac=no".

When multiple tasks generate to the same ip in l3 mode (i.e. with arp
support), all those tasks generate arp requests. we need to make sure
that they all receive a arp-reply i.e. that the master broadcast
the reply to all those cores.

This adds support for tasks in l3 submode receiving from ports but
transmitting to rings.
ARP related information is exchanged between tasks through master core.
Tasks transmitting to physical ports are responsible to transmit arp
related packets. Tasks not transmitting to physical ports (and using
rings) should not try to transmit arp packets. Transmitting arp
packets through ring would be more complex, as we would need extra information
(within the mbuf) to distinguish for instance an arp reply comoing from the
network and an arp reply coming from a core (as a reply to an arp request).

Different checks were done when setting the generator pkt_size.
In case of wrong pkt_size (e.g. too big) an error was printed but
the pkt_size was still set causing a potential corruption.
In addition, in case of a packet size incompatible with some
of the packet fields (e.g. latency data) PROX was panicing
while this should not happen runtime for such an error.

The l3 submode was not supported in nop mode, as the nop mode uses some
specific nop thread (and not generic). When L3 is specified, the nop mode
must use the generic thread. In addition the l3 submode is implemented
differently than other submodes. It is not supported through task_init
structures (i.e. each task does not have to explicitely tell that it
supports l3 submode). But this prevented to run both a nop with no submode
and a nop with a l3 submode. Note that nop with l3 is usually not very useful
- it handles arp (requests and response) but as nop, it does not swap IP
addresses. So with a real switch, the packets transmitted will be received
back... and l3 mode is usually mainly usefull when using a switch.
However, there is at least one nop mode where l3 submode makes sense:
when the nop does not transmit. In such cases, for instace used in
conjunction with a gen l3, the nop receives all packets and forward
the arp requests and responses to the master for handling.

In lwAFTR (ipv6 de-encapsulate) the generated ipv4 packet requires an IP
checksum, otherwise this packet is dropped in Openstack. (Openstack is
much stricter than baremetal) Some fields in the header need to be
initialized.
Add flag in Makefile which when enabled will build to include the generate
the IP checksum in the build. FLAG = GEN_DECAP_IPV6_TO_IPV4_CKSUM=y
Not include in default build.

- Adjust handle functions to PROX-v035+ prototype, returning 0 when all
packets have been handled.
- Because cryptodev API was modified in DPDK 17.08, many changes would
be necessary to support it. For the moment, just exclude handle_esp.c
from PROX build when using DPDK 17.08+, which will be supported later.
- Cleanup:
- consistent use of PROX_PANIC to cleanly fail on errors
- consistent use of OUT_DISCARD to drop unhandled packets
- remove "__attribute__((unused))" when parameter is actually used
- remove unused defines, fields and variables
