The following patchset contains Netfilter updates for net-next, they are:

1) Incorrect uapi header comment in bitwise, from Jeremy Sowden.

2) Fetch flow statistics if flow is still active.

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.

9) Remove indirect calls in xt_hashlimit, from Florian Westphal.

10) Add nf_flow_offload_tuple() helper to consolidate code.

11) Add nf_flow_table_offload_cmd() helper function.

12) A few whitespace cleanups in nf_tables in bitwise and the bitmap/hash
    set types, from Jeremy Sowden.

13) Cleanup netlink attribute checks in bitwise, from Jeremy Sowden.

14) Replace goto by return in error path of nft_bitwise_dump(), from
    Jeremy Sowden.

15) Add bitwise operation netlink attribute, also from Jeremy.

16) Add nft_bitwise_init_bool(), from Jeremy Sowden.

17) Add nft_bitwise_eval_bool(), also from Jeremy.

18) Add nft_bitwise_dump_bool(), from Jeremy Sowden.
