Make require_cmd() calls explicit about whether commands are needed
locally, remotely, or both.
Since require_cmd() defaults to local=True, tests should explicitly set
local=False when commands are only needed remotely.
- socat: Set local=False since it's only needed on remote hosts.
- iperf3: Use single call with both local=True and remote=True since
it's needed on both hosts.
This avoids unnecessary test failures when commands are missing locally
but available remotely where actually needed, and consolidates a
duplicate require_cmd() call into single call that checks both hosts.

A few packets may still be sent out during the termination of iperf
processes. These late packets cause failures in rss_ctx.py when they
arrive on queues expected to be empty.
Example failure observed:
Check failed 2 != 0 traffic on inactive queues (context 1):
[0, 0, 1, 1, 386385, 397196, 0, 0, 0, 0, ...]
Check failed 4 != 0 traffic on inactive queues (context 2):
[0, 0, 0, 0, 2, 2, 247152, 253013, 0, 0, ...]
Check failed 2 != 0 traffic on inactive queues (context 3):
[0, 0, 0, 0, 0, 0, 1, 1, 282434, 283070, ...]
To avoid such failures, wait until all client sockets for the requested
port are either closed or in the TIME_WAIT state.

These tests don't clean up after themselves, don't use the disruptive
annotations, don't get included in make install etc. etc. The tests
were added before we have any "HW" runner, so the issues were missed.
Our CI doesn't have any way of excluding broken tests, remove these
for now to stop the random pollution of results due to broken env.
We can always add them back once / if fixed.

Add selftest case to check the send and receive throughput.
Supported link modes between local NIC driver and partner
are varied. Then send and receive throughput is captured
and verified. Test uses iperf3 tool.
Add iperf3 server/client function in GenerateTraffic class.

Add tests focusing on indirection table configuration and
creating extra RSS contexts in drivers which support it.
$ export NETIF=eth0 REMOTE_...
$ ./drivers/net/hw/rss_ctx.py
KTAP version 1

ok 1 rss_ctx.test_rss_key_indir
ok 2 rss_ctx.test_rss_context
ok 3 rss_ctx.test_rss_context4
# Increasing queue count 44 -> 66
# Failed to create context 32, trying to test what we got
ok 4 rss_ctx.test_rss_context32 # SKIP Tested only 31 contexts, wanted 32
ok 5 rss_ctx.test_rss_context_overlap

# .. sprays traffic like a headless chicken ..

ok 8 rss_ctx.test_rss_context4_create_with_cfg
# Totals: pass:6 fail:1 xfail:0 xpass:0 skip:1 error:0
Note that rss_ctx.test_rss_context_out_of_order fails with the device
I tested with, but it seems to be a device / driver bug.

Teach the load generator how to wait for at least given number
of packets to be received. This will be useful for filtering
where we'll want to send a non-trivial number of packets and
make sure they landed in right queues.

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.
