Merge branch 'net-make-rss-rxnfc-semantics-more-explicit'
Edward Cree says:
====================
net: make RSS+RXNFC semantics more explicit
The original semantics of ntuple filters with FLOW_RSS were not
fully understood by all drivers, some ignoring the ring_cookie from
the flow rule. Require this support to be explicitly declared by
the driver for filters relying on it to be inserted, and add self-
test coverage for this functionality.
Also teach ethtool_check_max_channel() about this.
