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.
