Pull networking fixes from David Miller:
 "I'm sending this out, in particular, to get the iwlwifi fix
  propagated:

   1) Fix build due to missing include in i40e driver, from Lucas
      Tanure.

   2) Memory leak in openvswitch port allocation, from Chirstoph Jaeger.

   3) Check DMA mapping errors in myri10ge, from Stanislaw Gruszka.

   4) Fix various deadlock scenerios in sunvnet driver, from Sowmini
      Varadhan.

   5) Fix cxgb4i build failures with incompatible Kconfig settings of
      the driver vs ipv6, from Anish Bhatt.

   6) Fix generation of ACK packet timestamps in the presence of TSO
      which will be split up, from Willem de Bruijn.

   7) Don't enable sched scan in iwlwifi driver, it causes firmware
      crashes in some revisions.  From Emmanuel Grumbach.

   8) Revert a macvlan simplification that causes crashes.

   9) Handle RTT calculations properly in the presence of repair'd SKBs,
      from Andrey Vagin.

  10) SIT tunnel lookup uses wrong device index in compares, from
      Shmulik Ladkani.

  11) Handle MTU reductions in TCP properly for ipv4 mapped ipv6
      sockets, from Neal Cardwell.

  12) Add missing annotations in rhashtable code, from Thomas Graf.

  13) Fix false interpretation of two RTOs as being from the same TCP
      loss event in the FRTO code, from Neal Cardwell"
