There are two selftest scenarios for ARRAY BIST(Board Integrated System

1. Perform IFS ARRAY BIST tests once on each CPU.
2. Perform IFS ARRAY BIST tests on a random CPU with 3 rounds.
These are not meant to be exhaustive, but are some minimal tests for

Two selftests are added to verify IFS scan test feature:

This patch creates two sets of sock_ops that call out to the SYSCALL

According to the test environment, the mount point of the test's working
directory may be shared or not, which changes the visibility of the
nested "tmp" mount point for the test's parent process calling
umount("tmp").

points are

Add support for (yet again) more RVA23U64 missing extensions. Add
support for Zcmop, Zca, Zcf, Zcd and Zcb extensions isa string parsing,
hwprobe and kvm support. Zce, Zcmt and Zcmp extensions have been left
out since they target microcontrollers/embedded CPUs and are not needed
by RVA23U64.

Bugs in memory allocation failure paths are quite common.
Add a test exercising those paths based on qstat and page pool
failure hook.
Running on bnxt:
# ./drivers/net/hw/pp_alloc_fail.py
KTAP version 1
1..1
# ethtool -G change retval: success
ok 1 pp_alloc_fail.test_pp_alloc
# Totals
While we are not very interested in testing performance
it's useful to be able to generate a lot of traffic.
iperf is the simplest way of getting relatively high PPS.

Because of caching / recycling using the general page allocation
failures to induce errors in page pool allocation is very hard.
