Only 1 egress and 1 ingress rule each can be offloaded on the underlying port. Patch 1 adds support for TC-MATCHALL classifier offload on the egress side. TC-POLICE is the only action that can be offloaded on the egress side and is used to rate limit all outgoing traffic to specified max rate. Patch 2 adds support for TC-MATCHALL classifier offload on the ingress side. The same set of actions supported by existing TC-FLOWER classifier offload can be applied on all the incoming traffic. Thanks, Rahul --- v2: - Added check to reject flow block sharing for policers in patch 1. - Removed logic to fetch free index from end of TCAM in patch 2. Must maintain the same ordering as in kernel.
