====================
netfilter/ipvs fixes for net

The following patchset contains netfilter/ipvs fixes, they are:

1) Small fix for the FTP helper in IPVS, a diff variable may be left
   unset when CONFIG_IP_VS_IPV6 is set. Patch from Dan Carpenter.

2) Fix nf_tables port NAT in little endian archs, patch from leroy
   christophe.

3) Fix race condition between conntrack confirmation and flush from
   userspace. This is the second reincarnation to resolve this problem.

4) Make sure inner messages in the batch come with the nfnetlink header.

5) Relax strict check from nfnetlink_bind() that may break old userspace
   applications using all 1s group mask.

6) Schedule removal of chains once no sets and rules refer to them in
   the new nf_tables ruleset flush command. Reported by Asbjoern Sloth
   Toennesen.

Note that this batch comes later than usual because of the short
winter holidays.
