Currently established connections are not offloaded if the filter has a "ct commit" action. This behavior will not offload connections of the following scenario: $ tc_filter add dev $DEV ingress protocol ip prio 1 flower \ ct_state -trk \ action ct commit action goto chain 1 $ tc_filter add dev $DEV ingress protocol ip chain 1 prio 1 flower \ action mirred egress redirect dev $DEV2 $ tc_filter add dev $DEV2 ingress protocol ip prio 1 flower \ action ct commit action goto chain 1 $ tc_filter add dev $DEV2 ingress protocol ip prio 1 chain 1 flower \ ct_state +trk+est \ action mirred egress redirect dev $DEV Offload established connections, regardless of the commit flag.
