cxgb4: add basic tc flower offload support
Add support to add/remove flows for offload. Following match
and action are supported for offloading a flow:
Match: ether-protocol, IPv4/IPv6 addresses, L4 ports (TCP/UDP)
Action: drop, redirect to another port on the device.
The qualifying flows can have accompanying mask information.
