From: Edward Cree <[email protected]>
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
