net: sched: add ingress mirred action to hardware IR (48e584ac) · Commits · 戴 / test

TC mirred actions (redirect and mirred) can send to egress or ingress of a device. Currently only egress is used for hw offload rules. Modify the intermediate representation for hw offload to include mirred actions that go to ingress. This gives drivers access to such rules and can decide whether or not to offload them.
