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

1) TCP conntrack now only evaluates window negotiation for packets in
   the REPLY direction, from Ryan Schaefer. Otherwise SYN retransmissions
   trigger incorrect window scale negotiation. From Ryan Schaefer.

2) Restrict tunnel objects to NFPROTO_NETDEV which is where it makes sense
   to use this object type.

3) Fix conntrack pick up from the middle of SCTP_CID_SHUTDOWN_ACK packets.
   From Xin Long.

4) Another attempt from Jozsef Kadlecsik to address the slow down of the
   swap command in ipset.

5) Replace a BUG_ON by WARN_ON_ONCE in nf_log, and consolidate check for
   the case that the logger is NULL from the read side lock section.

6) Address lack of sanitization for custom expectations. Restrict layer 3
   and 4 families to what it is supported by userspace.
