====================
netfilter: updates for net-next

The following patchset contains Netfilter updates for *net-next*,
including changes to IPv6 stack and updates to IPVS from Julian Anastasov.

1) ipv6: export fib6_lookup for nft_fib_ipv6 module
2) factor out ipv6_anycast_destination logic so its usable without
   dst_entry.  These are dependencies for patch 3.
3) switch nft_fib_ipv6 module to no longer need temporary dst_entry
   object allocations by using fib6_lookup() + RCU.
   This gets us ~13% higher packet rate in my tests.

Patches 4 to 8, from Eric Dumazet, zap sk_callback_lock usage in
netfilter.  Patch 9 removes another sk_callback_lock instance.

Remaining patches, from Julian Anastasov, improve IPVS, Quoting Julian:
* Add infrastructure for resizable hash tables based on hlist_bl.
* Change the 256-bucket service hash table to be resizable.
* Change the global connection table to be per-net and resizable.
* Make connection hashing more secure for setups with multiple services.
