Pull networking fixes from David Miller:

1) TCP can chop up SACK'd SKBs below below the unacked send sequence and
   that breaks lots of stuff.  Fix from Neal Cardwell.

2) There is code in ipv6 to properly join and leave the all-routers
   multicast code when the forwarding setting is changed, but once
   forwarding is turned on, we don't do the join for newly registered
   devices.  Fix from Li Wei.

3) Netfilter's NAT module autoload in ctnetlink drops a spinlock around
   a sleeping call, problem is this code path doesn't actually hold that
   lock.  Fix from Pablo Neira Ayuso.

4) TG3 uses the wrong interfaces to hook into the new byte queue limit
   support.  It uses the device level interfaces, which is fine for
   single queue devices, but on more recent chips this driver supports
   multiqueue so we have to use the multiqueue BQL APIs.  Fix from Tom
   Herbert.

5) r8169 resume fix from Francois Romieu.

6) Add some cxgb4 device IDs, from Vipul Pandya.

* git://git.kernel.org/pub/scm/linux/kernel/git/davem/net:
  IPv6: Fix not join all-router mcast group when forwarding set.
  caif-hsi: Set default MTU to 4096
  cxgb4vf: Add support for Chelsio's T480-CR and T440-LP-CR adapters
  cxgb4: Add support for Chelsio's T480-CR and T440-LP-CR adapters
  mlx4_core: remove buggy sched_queue masking
  netfilter: nf_conntrack: fix early_drop with reliable event delivery
  bridge: netfilter: don't call iptables on vlan packets if sysctl is off
  netfilter: bridge: fix wrong pointer dereference
  netfilter: ctnetlink: remove incorrect spin_[un]lock_bh on NAT module autoload
  netfilter: ebtables: fix wrong name length while copying to user-space
  r8169: runtime resume before shutdown.
  tcp: fix tcp_shift_skb_data() to not shift SACKed data below snd_una
  tg3: Fix to use multi queue BQL interfaces
