The "dp core stats" command supported, as other commands, multiple cores
but not multiple tasks. It now supports both (e.g. dp core stats 1-2 0-1).
This is necessary so that users can collect all statistics from PROX in one
command line.
It will return similar information on the screen or through the socket:
- if the syntax is wrong (e.g. missing task, too many cores or tasks, ...)
=> an error message is printed on the screen, and the single error line
"error: invalid syntax" is returned through the socket
- if the syntax is correct
=> one line is printed or returned for each core/task pair
=> if the core/task pair is invalid, the line reports an error
=> otherwise, the line provides dataplane statistics for the core/task pair,
with the core_id and task_id added, either at the end of the line returned
through the socket, or at the beginning of the line printed on the screen.
This means a change in behaviour when using the socket: before, when an error
happened (e.g. bad task), then nothing was returned which made it difficult for
the script to catch the syntax error.
Similar behaviour could/should be implemented for other commands.
However, care must be taken as some scripts like NSB might count the number
of lines within the output, or the number of items within the line.
This should not be an issue for dp core stats as NSB does not use it, and other
PROX scripts do not count the number of items and will be adjusted to count the
number of lines.

Warning:
This change breaks backward-compatibility of PROX socket scripting API,
because the "total TX fail" count is reported before the "last TSC"
field.
As a result, PROX scripts that make use of the "dp core stats" command,
such as the core_stats() method in helper-scripts/openstackrapid/prox_ctrl.py,
MUST be reworked to correctly parse the returned set of fields.

When performing some zero packet loss performance testing on dataplane, it
is important (not) to count non dataplane packets. For instance, one might
receive uexpected packets from a switch, or ARP packets. Or one might need
to transmit ARP packets. Such packets should not be counted as dataplane
packets as for thse packets there is no 1:1 mapping between transmitted
packets and received packets.
To support this, the counters reporting numbers of transmitted and received
packets remain unchanged but two new counters have been added to PROX,
counting respectively number of received and number of transmitted
non-dataplane packets.
On RX side, packets are counsidered as non-dataplane if being ARP or if
they do not countain the proper signature
On TX side, ARP packets are not considered as dataplane packets.
This feature requires configuration of signature.
"dp core stats" command has been added

JIRA: YARDSTICK-1220
Implemented new "multi port stats <port list>" command, which returns a
semi-colon-separated list of comma-separated values:
- port id
- total (at last_tsc) for rx_pkts, tx_pkts, no_mbufs, ierrors + imissed
- last_tsc

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)..

Command parser could have been crashing if a wrong core/task was
used in pkt_size command. For some other commands both an error
and a warning were printed in case of errors.

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.

JIRA: SAMPLEVNF-55
PROX is a DPDK-based application implementing Telco use-cases such as
a simplified BRAS/BNG, light-weight AFTR... It also allows configuring
finer grained network functions like QoS, Routing, load-balancing...
(We are moving PROX version v039 to sampleVNF
