Subject: [PATCH net-next 0/4] selftests: drv-net: rss_ctx: add tests for RSS contexts

Add a few tests exercising RSS context API.
In addition to basic sanity checks, tests add RSS contexts,
n-tuple rule to direct traffic to them (based on dst port),
and qstats to make sure traffic landed where we expected.

  $ ./drivers/net/hw/rss_ctx.py
  KTAP version 1
  1..6
  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
  ok 6 rss_ctx.test_rss_context_overlap2
  # Totals: pass:5 fail:0 xfail:0 xpass:0 skip:1 error:0
