Pull networking updates from David Miller:
 "Much more accumulated than I would have liked due to an unexpected
  bout with a nasty flu:

   1) AH and ESP input don't set ECN field correctly because the
      transport head of the SKB isn't set correctly, fix from Li
      RongQing.

   2) If netfilter conntrack zones are disabled, we can return an
      uninitialized variable instead of the proper error code.  Fix from
      Borislav Petkov.

   3) Fix double SKB free in ath9k driver beacon handling, from Felix
      Feitkau.

   4) Remove bogus assumption about netns cleanup ordering in
      nf_conntrack, from Pablo Neira Ayuso.

   5) Remove a bogus BUG_ON in the new TCP fastopen code, from Eric
      Dumazet.  It uses spin_is_locked() in it's test and is therefore
      unsuitable for UP.

   6) Fix SELINUX labelling regressions added by the tuntap multiqueue
      changes, from Paul Moore.

   7) Fix CRC errors with jumbo frame receive in tg3 driver, from Nithin
      Nayak Sujir.

   8) CXGB4 driver sets interrupt coalescing parameters only on first
      queue, rather than all of them.  Fix from Thadeu Lima de Souza
      Cascardo.

   9) Fix regression in the dispatch of read/write registers in dm9601
      driver, from Tushar Behera.

  10) ipv6_append_data miscalculates header length, from Romain KUNTZ.

  11) Fix PMTU handling regressions on ipv4 routes, from Steffen
      Klassert, Timo Teräs, and Julian Anastasov.

  12) In 3c574_cs driver, add necessary parenthesis to "x << y & z"
      expression.  From Nickolai Zeldovich.

  13) macvlan_get_size() causes underallocation netlink message space,
      fix from Eric Dumazet.

  14) Avoid division by zero in xfrm_replay_advance_bmp(), from Nickolai
      Zeldovich.  Amusingly the zero check was already there, we were
      just performing it after the modulus :-)

  15) Some more splice bug fixes from Eric Dumazet, which fix things
      mostly eminating from how we now more aggressively use high-order
      pages in SKBs.

  16) Fix size calculation bug when freeing hash tables in the IPSEC
      xfrm code, from Michal Kubecek.

  17) Fix PMTU event propagation into socket cached routes, from Steffen
      Klassert.

  18) Fix off by one in TX buffer release in netxen driver, from Eric
      Dumazet.

  19) Fix rediculous memory allocation requirements introduced by the
      tuntap multiqueue changes, from Jason Wang.

  20) Remove bogus AMD platform workaround in r8169 driver that causes
      major problems in normal operation, from Timo Teräs.

  21) virtio-net set affinity and select queue don't handle
      discontiguous cpu numbers properly, fix from Wanlong Gao.

  22) Fix a route refcounting issue in loopback driver, from Eric
      Dumazet.  There's a similar fix coming that we might add to the
      macvlan driver as well.

  23) Fix SKB leaks in batman-adv's distributed arp table code, from
      Matthias Schiffer.

  24) r8169 driver gives descriptor ownership back the hardware before
      we're done reading the VLAN tag out of it, fix from Francois
      Romieu.

  25) Checksums not calculated properly in GRE tunnel driver fix from
      Pravin B Shelar.

26) Fix SCTP memory leak on namespace exit."
