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.
