3) Restrict flow matching on hardware based on input device.

4) Add nf_flow_offload_work_alloc() helper function.

5) Remove the last client of the FLOW_OFFLOAD_DYING flag, use teardown
   instead.

6) Use atomic bitwise operation to operate with flow flags.

7) Add nf_flowtable_hw_offload() helper function to check for the
   NF_FLOWTABLE_HW_OFFLOAD flag.

8) Add NF_FLOW_HW_REFRESH to retry hardware offload from the flowtable
   software datapath.
