Subject: [PATCH net-next v1 0/3] io_uring/zcrx: fix selftests and add new test for rss ctx

Update io_uring zero copy receive selftest. Patch 1 does a requested
cleanup to use defer() for undoing ethtool actions during the test and
restoring the NIC under test back to its original state.

Patch 2 adds a required call to set hds_thresh to 0. This is needed for
the queue API.

Patch 3 adds a new test case for steering into RSS contexts. A real
application using io_uring zero copy receive relies on this working to
shard work across multiple queues. There seems to be some
differences/bugs with steering into RSS contexts and individual queues.

David Wei (3):
  io_uring/zcrx: selftests: switch to using defer() for cleanup
  io_uring/zcrx: selftests: set hds_thresh to 0
  io_uring/zcrx: selftests: add test case for rss ctx
