Pull networking fixes from David Miller:
 "Some holiday bug fixes for 3.13...  There is still one bug I'd like to
  get fixed before 3.13-final.

  The vlan code erroneously assignes the header ops of the underlying
  real device to the VLAN device above it when the real device can
  hardware offload VLAN handling.  That's completely bogus because
  header ops are tied to the device type, so they only expect to see a
  'dev' argument compatible with their ops.

  The fix is the have the VLAN code use a special set of header ops that
  does the pass-thru correctly, by calling the underlying real device's
  header ops but _also_ passing in the real device instead of the VLAN
  device.

  That fix is currently waiting some testing.

  Anyways, of note here:

   1) Fix bitmap edge case in radiotap, from Johannes Berg.

   2) Fix oops on driver unload in rtlwifi, from Larry Finger.

   3) Bonding doesn't do locking correctly during speed/duplex/link
      changes, from Ding Tianhong.

   4) Fix header parsing in GRE code, this bug has been around for a few
      releases.  From Timo Teräs.

   5) SIT tunnel driver MTU check needs to take GSO into account, from
      Eric Dumazet.

   6) Minor info leak in inet_diag, from Daniel Borkmann.

   7) Info leak in YAM hamradio driver, from Salva Peiró.

   8) Fix route expiration state handling in ipv6 routing code, from Li
      RongQing.

   9) DCCP probe module does not check request_module()'s return value,
      from Wang Weidong.

  10) cpsw driver passes NULL device names to request_irq(), from
      Mugunthan V N.

  11) Prevent a NULL splat in RDS binding code, from Sasha Levin.

  12) Fix 4G overflow test in tg3 driver, from Nithin Sujir.

  13) Cure use after free in arc_emac and fec driver's software
      timestamp handling, from Eric Dumazet.

  14) SIT driver can fail to release the route when
      iptunnel_handle_offloads() throws an error.  From Li RongQing.

  15) Several batman-adv fixes from Simon Wunderlich and Antonio
      Quartulli.

  16) Fix deadlock during TIPC socket release, from Ying Xue.

  17) Fix regression in ROSE protocol recvmsg() msg_name handling, from
      Florian Westphal.

  18) stmmac PTP support releases wrong spinlock, from Vince Bridgers"
