[net-next,00/11] Netfilter updates for net-next

Hi,

The following patchset contains Netfilter updates for net-next:

1) Replace unnecessary list_for_each_entry_continue() in nf_tables,
   from Jakob Koschel.

2) Add struct nf_conntrack_net_ecache to conntrack event cache and
   use it, from Florian Westphal.

3) Refactor ctnetlink_dump_list(), also from Florian.

4) Bump module reference counter on cttimeout object addition/removal,
   from Florian.

5) Consolidate nf_log MAC printer, from Phil Sutter.

6) Add basic logging support for unknown ethertype, from Phil Sutter.

7) Consolidate check for sysctl nf_log_all_netns toggle, also from Phil.

8) Replace hardcode value in nft_bitwise, from Jeremy Sowden.

9) Rename BASIC-like goto tags in nft_bitwise to more meaningful names,
   also from Jeremy.

10) nft_fib support for reverse path filtering with policy-based routing
    on iif. Extend selftests to cover for this new usecase, from Florian.

Please, pull these changes from:

Thanks.
