====================
Netfilter fixes for net

Patch #1 restores NFPROTO_INET with nft_compat, from Ignat Korchagin.

Patch #2 fixes an issue with bridge netfilter and broadcast/multicast
packets.

There is a day 0 bug in br_netfilter when used with connection tracking.

Conntrack assumes that an nf_conn structure that is not yet added to
hash table ("unconfirmed"), is only visible by the current cpu that is
processing the sk_buff.

For bridge this isn't true, sk_buff can get cloned in between, and
clones can be processed in parallel on different cpu.

This patch disables NAT and conntrack helpers for multicast packets.

Patch #3 adds a selftest to cover for the br_netfilter bug.
