From: Edward Cree <ecree.xilinx(a)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

[ Upstream commit 3e360ef0c0a1fb6ce9a302e40b8057c41ba8a9d2 ]
When building for streaming SVE the irritator for SVE skips updates of both
P0 and FFR. While FFR is skipped since it might not be present there is no
reason to skip corrupting P0 so switch to an instruction valid in streaming
mode and move the ifdef.
