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

Pull networking fixes from David Miller:
 "A pile of fixes in response to yesterday's big merge.  The SCTP HMAC
  thing hasn't been addressed yet, I'll take care of that myself if Neil
  and Vlad don't show signs of life by tomorrow.

   1) Use after free of SKB in tuntap code.  Fix by Eric Dumazet,
      reported by Dave Jones.

   2) NFC LLCP code emits annoying kernel log message, triggerable by
      the user.  From Dave Jones.

   3) Fix several endianness bugs noticed by sparse in the bridging
      code, from Stephen Hemminger.

   4) Ipv6 NDISC code doesn't take padding into account properly, fix
      from YOSHIFUJI Hideaki.

   5) Add missing docs to ethtool_flow_ext struct, from Yan Burman."

* git://git.kernel.org/pub/scm/linux/kernel/git/davem/net:
  bridge: fix icmpv6 endian bug and other sparse warnings
  net: ethool: Document struct ethtool_flow_ext
  ndisc: Fix padding error in link-layer address option.
  tuntap: dont use skb after netif_rx_ni(skb)
  nfc: remove noisy message from llcp_sock_sendmsg
