====================
Netfilter updates for net-next

The following batch contains Netfilter/IPVS updates for your net-next tree:

1) Simplify log infrastructure modularity: Merge ipv4, ipv6, bridge,
   netdev and ARP families to nf_log_syslog.c. Add module softdeps.
   This fixes a rare deadlock condition that might occur when log
   module autoload is required. From Florian Westphal.

2) Moves part of netfilter related pernet data from struct net to
   net_generic() infrastructure. All of these users can be modules,
   so if they are not loaded there is no need to waste space. Size
   reduction is 7 cachelines on x86_64, also from Florian.

2) Update nftables audit support to report events once per table,
   to get it aligned with iptables. From Richard Guy Briggs.

3) Check for stale routes from the flowtable garbage collector path.
   This is fixing IPv6 which breaks due missing check for the dst_cookie.

4) Add a nfnl_fill_hdr() function to simplify netlink + nfnetlink
   headers setup.

5) Remove documentation on several statified functions.

6) Remove printk on netns creation for the FTP IPVS tracker,
   from Florian Westphal.

7) Remove unnecessary nf_tables_destroy_list_lock spinlock
   initialization, from Yang Yingliang.

7) Remove a duplicated forward declaration in ipset,
   from Wan Jiabing.
