Subject: [PATCH net-next] octeontx2-pf: TC flower offload support for rxqueue mapping
Date: Mon, 19 Jun 2023 11:36:38 +0530 [thread overview]
Message-ID: <20230619060638.1032304-1-rkannoth@marvell.com> (raw)
TC rule support to offload rx queue mapping rules.
Eg:
tc filter add dev eth2 ingress protocol ip flower \
dst_ip 192.168.8.100 \
action skbedit queue_mapping 4 skip_sw
action mirred ingress redirect dev eth5
Packets destined to 192.168.8.100 will be forwarded to rx
queue 4 of eth5 interface.

queue 4 of eth2 interface.
