SSO GGRPs i.e. queue uses DRAM & SRAM buffers to hold in-flight
events. By default the buffers are assigned to the SSO GGRPs to
satisfy minimum HW requirements. SSO is free to assign the remaining
buffers to GGRPs based on a preconfigured threshold.
We can control the QoS of SSO GGRP by modifying the above mentioned
thresholds. GGRPs that have higher importance can be assigned higher
thresholds than the rest.
Example:
--dev "0002:0e:00.0,qos=[1-50-50-50]" // [Qx-XAQ-TAQ-IAQ]
Qx -> Event queue Aka SSO GGRP.
XAQ -> DRAM In-flights.
TAQ & IAQ -> SRAM In-flights.

Replace the mbuf pointer array in the event eth Rx adapter
callback with an event array. Using an event array allows
the application to change attributes of the events enqueued
by the SW adapter.
The callback can drop packets and populate a callback
argument with the number of dropped packets. Add a Rx adapter
stats field to keep track of the total number of dropped packets.
This commit removes the experimental tags from
the callback and stats APIs, the experimental tag from eventdev
is also removed and eventdev functions become part of the

This patch enables need_wakeup flag for Tx and fill rings, when this
flag is set by the driver, it means that the userspace application has
to explicitly wake up the kernel Rx or kernel Tx processing by issuing
a syscall. Poll() can wake up both and sendto() or its alternatives
will wake up Tx processing only.
This feature is to provide efficient support for case that application
and driver executing on the same core.

It can be useful to use pcap files for some rudimental performance
testing. This patch enables this functionality in the pcap driver.
At a high level, this works by creating a ring of sufficient size to
store the packets in the pcap file passed to the application. When the
rx function for this mode is called, packets are dequeued from the ring
for use by the application and also enqueued back on to the ring to be
"received" again.
A tx_drop mode is also added since transmitting to a tx_pcap file isn't
desirable at a high traffic rate.
Jumbo frames are not supported in this mode. When filling the ring at rx
queue setup time, the presence of multi segment mbufs is checked for.
The PMD will exit on detection of these multi segment mbufs.

This commit replaces rte_rand()'s use of lrand48() with a DPDK-native
combined Linear Feedback Shift Register (LFSR) (also known as
Tausworthe) pseudo-random number generator.
This generator is faster and produces better-quality random numbers
than the linear congruential generator (LCG) of lib's lrand48(). The
implementation, as opposed to lrand48(), is multi-thread safe in
regards to concurrent rte_rand() calls from different lcore threads.
A LCG is still used, but only to seed the five per-lcore LFSR
sequences.
In addition, this patch also addresses the issue of the legacy
implementation only producing 62 bits of pseudo randomness, while the
API requires all 64 bits to be random.
This pseudo-random number generator is not cryptographically secure -
just like lrand48().

The busy percentage is calculated by recording the poll_count
and when the count reaches a defined value the total
cycles it took is measured and compared with minimum and maximum
reference cycles and busy rate is set according to either 0% or
50% or 100%.
