Subject: [Intel-wired-lan] [PATCH iwl-next] igb: flower: validate control flags
Date: Tue, 16 Apr 2024 14:43:35 +0000 [thread overview]
Message-ID: <20240416144335.15353-1-ast@fiberby.net> (raw)
This driver currently doesn't support any control flags.
Use flow_rule_match_has_control_flags() to check for control flags,
such as can be set through `tc flower ... ip_flags frag`.
In case any control flags are masked, flow_rule_match_has_control_flags()
sets a NL extended error message, and we return -EOPNOTSUPP.
Only compile-tested.
