[net-next,v3,2/2] octeontx2-pf: TC flower offload support for mirror
Commit Message
This patch extends TC flower offload support for mirroring
ingress/egress traffic to a different PF/VF. Below is an example
command,
'tc filter add dev eth1 ingress protocol ip flower src_ip <ip-addr>
skip_sw action mirred ingress mirror dev eth2'

Thank you for your review!
Please, additionally try to trim away the irrelevant part of the patch
when replying (in this case almost everything). That helps a lot
following the discussion, especially on long patches, thanks!
@Suman: please retain Wojciech's tag on next revision of this series.
Cheers,
Paolo
