Netfilter/IPVS updates for net-next

Hi David,

The following patchset contains Netfilter/IPVS updates for your net-next tree. A couple of new features for nf_tables, and unsorted cleanups and incremental updates for the Netfilter tree. More specifically, they are:

1) Allow to check for TCP option presence via nft_exthdr, patch from Phil Sutter.

2) Add symmetric hash support to nft_hash, from Laura Garcia Liebana.

3) Use pr_cont() in ebt_log, from Joe Perches.

4) Remove some dead code in arp_tables reported via static analysis tool, from Colin Ian King.

5) Consolidate nf_tables expression validation, from Liping Zhang.

6) Consolidate set lookup via nft_set_lookup().

7) Remove unnecessary rcu read lock side in bridge netfilter, from Florian Westphal.

8) Remove unused variable in nf_reject_ipv4, from Tahee Yoo.

9) Pass nft_ctx struct to object initialization indirections, from Florian Westphal.

10) Add code to integrate conntrack helper into nf_tables, also from Florian.

11) Allow to check if interface index or name exists via NFTA_FIB_F_PRESENT, from Phil Sutter.

12) Simplify resolve_normal_ct(), from Florian.

13) Use per-limit spinlock in nft_limit and xt_limit, from Liping Zhang.

14) Use rwlock in nft_set_rbtree set, also from Liping Zhang.

15) One patch to remove a useless printk at netns init path in ipvs, and several patches to document IPVS knobs.

16) Use refcount_t for reference counter in the Netfilter/IPVS code, from Elena Reshetova.
