Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net 

Pull networking fixes from David Miller:
 "This is primarily to get those r8169 reverts sorted, but other fixes
  have accumulated meanwhile.

   1) Revert two r8169 changes to fix suspend/resume for some users,
      from Francois Romieu.

   2) PCI dma mapping errors in atl1c are not checked for and this cause
      hard crashes for some users, from Xiong Huang.

   3) In 3.8.x we merged the removal of the EXPERIMENTAL dependency for
      'dlm' but the same patch for 'sctp' got lost somewhere, resulting
      in the potential for build errors since there are cross
      dependencies.  From Kees Cook.

   4) SCTP's ipv6 socket route validation makes boolean tests
      incorrectly, fix from Daniel Borkmann.

   5) mac80211 does sizeof(ptr) instead of (sizeof(ptr) * nelem), from
      Cong Ding.

   6) arp_rcv() can crash on shared non-linear packets, from Eric
      Dumazet.

   7) Avoid crashes in macvtap by setting ->gso_type consistently in
      ixgbe, qlcnic, and bnx2x drivers.  From Michael S Tsirkin and
      Alexander Duyck.

   8) Trinity fuzzer spots infinite loop in __skb_recv_datagram(), fix
      from Eric Dumazet.

   9) STP protocol frames should use high packet priority, otherwise an
      overloaded bridge can get stuck.  From Stephen Hemminger.

  10) The HTB packet scheduler was converted some time ago to store
      internal timestamps in nanoseconds, but we don't convert back into
      psched ticks for the user during dumps.  Fix from Jiri Pirko.

  11) mwl8k channel table doesn't set the .band field properly,
      resulting in NULL pointer derefs.  Fix from Jonas Gorski.

  12) mac80211 doesn't accumulate channels properly during a scan so we
      can downgrade heavily to a much less desirable connection speed.
      Fix from Johannes Berg.

  13) PHY probe failure in stmmac can result in resource leaks and
      double MDIO registery later, from Giuseppe CAVALLARO.

  14) Correct ipv6 checksumming in ip6t_NPT netfilter module, also fix
      address prefix mangling, from YOSHIFUJI Hideaki."
