From: Edward Cree <ecree.xilinx@gmail.com>

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.

Edward Cree (5):
  net: ethtool: only allow set_rxnfc with rss + ring_cookie if driver
    opts in
  net: ethtool: account for RSS+RXNFC add semantics when checking
    channel count
  selftest: include dst-ip in ethtool ntuple rules
  selftest: validate RSS+ntuple filters with nonzero ring_cookie
  selftest: extend test_rss_context_queue_reconfigure for action
    addition
