Subject: [iwl-net v1] ice: tc: do default match on all profiles
Date: Tue, 12 Mar 2024 11:52:59 +0100 [thread overview]
Message-ID: <20240312105259.2450-1-michal.swiatkowski@linux.intel.com> (raw)
A simple non-tunnel rule (e.g. matching only on destination MAC) in
hardware will be hit only if the packet isn't a tunnel. In software
execution of the same command, the rule will match both tunnel and
non-tunnel packets.
Change the hardware behaviour to match tunnel and non-tunnel packets in
this case. Do this by considering all profiles when adding non-tunnel rule
(rule not added on tunnel, or not redirecting to tunnel).
Example command:
tc filter add dev pf0 ingress protocol ip flower skip_sw action mirred \
egress redirect dev pr0
It should match also tunneled packets, the same as command with skip_hw
will do in software.
Fixes: 9e300987d4a8 ("ice: VXLAN and Geneve TC support")
