Subject: [PATCH net-next v2 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.
v2 adds a test for removing contexts out of order. When testing
bnxt - either the new test or running more tests after the overlap
test makes the device act strangely. To the point where it may start
giving out ntuple IDs of 0 for all rules :S
Ed, could you try the tests with your device?
