Pull networking fixes from David Miller:
 "I'm hoping this is the very last batch of networking fixes for 3.13,
  here goes nothing:

   1) Fix crashes in VLAN's header_ops passthru.

   2) Bridge multicast code needs to use BH spinlocks to prevent
      deadlocks with timers.  From Curt Brune.

   3) ipv6 tunnels lack proper synchornization when updating percpu
      statistics.  From Li RongQing.

   4) Fixes to bnx2x driver from Yaniv Rosner, Dmitry Kravkov and Michal
      Kalderon.

   5) Avoid undefined operator evaluation order in llc code, from Daniel
      Borkmann.

   6) Error paths in various GSO offload paths do not unwind properly,
      in particular they must undo any modifications they have made to
      the SKB.  From Wei-Chun Chao.

   7) Fix RX refill races during restore in virtio-net, from Jason Wang.

   8) Fix SKB use after free in LLC code, from Daniel Borkmann.

   9) Missing unlock and OOPS in netpoll code when VLAN tag handling
      fails.

  10) Fix vxlan device attachment wrt ipv6, from Fan Du.

  11) Don't allow creating infiniband links to non-infiniband devices,
      from Hangbin Liu.

  12) Revert FEC phy reset active low change, it breaks things.  From
      Fabio Estevam.

  13) Fix header pointer handling in 6lowpan header building code, from
      Daniel Borkmann.

  14) Fix RSS handling in be2net driver, from Vasundhara Volam.

  15) Fix modem port indexing in HSO driver, from Dan Williams"
