Merge branch 'eth-fbnic-support-basic-rss-config-and-setting-channel-count'

Jakub Kicinski says:

====================
eth: fbnic: support basic RSS config and setting channel count

Add support for basic RSS config (indirection table, key get and set),
and changing the number of channels.

  # ./ksft-net-drv/run_kselftest.sh -t drivers/net/hw:rss_ctx.py
  TAP version 13
  1..1
  # timeout set to 0
  # selftests: drivers/net/hw: rss_ctx.py
  # KTAP version 1
  # 1..15
  # ok 1 rss_ctx.test_rss_key_indir
  # ok 2 rss_ctx.test_rss_queue_reconfigure
  # ok 3 rss_ctx.test_rss_resize
  # ok 4 rss_ctx.test_hitless_key_update

  .. the rest of the tests are for additional contexts so they
  get skipped..

The slicing of the patches (and bugs) are mine, but I'm keeping
Alex as the author on the patches where he wrote 100% of the code.
