Subject: [PATCH net-next 0/4] cxgb4: add support to offload tc flower

This series of patches add support to offload tc flower onto Chelsio
NICs.

Patch 1 adds basic skeleton to prepare for offloading tc flower flows.

Patch 2 adds support to add/remove flows for offload.  Flows can have
accompanying masks.  Following match and action are currently supported
for offload:
Match:  ether-protocol, IPv4/IPv6 addresses, L4 ports (TCP/UDP)
Action: drop, redirect to another port on the device.

Patch 3 adds support to offload tc-flower flows having
vlan actions: pop, push, and modify.

Patch 4 adds support to fetch stats for the offloaded tc flower flows
from hardware.

Support for offloading more match and action types are to be followed
in subsequent series.

Thanks,
Rahul
