Subject: [PATCH net-next 0/2] cxgb4: add TC-MATCHALL classifier offload

This series of patches add support to offload TC-MATCHALL classifier
to hardware to classify all outgoing and incoming traffic on the
underlying port. 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
