Pull networking fixes from David Miller:
 "Famouse last words: "final pull request" :-)

  I'm sending this because Jason Wang's fixes are pretty important

   1) Add missing per-cpu stats initialization to ip6_vti.  Otherwise
      lockdep spits out a call trace.  From Li RongQing.

   2) Fix NULL oops in wireless hwsim, from Javier Lopez

   3) TIPC deferred packet queue unlink must NULL out skb->next to avoid
      crashes.  From Erik Hugne

   4) Fix access to uninitialized buffer in nf_nat netfilter code, from
      Daniel Borkmann

   5) Fix lifetime of ipv6 loopback and SIT tunnel addresses, otherwise
      they basically timeout immediately.  From Hannes Frederic Sowa

   6) Fix DMA unmapping of TSO packets in bnx2x driver, from Michal
      Schmidt

   7) Do not allow L2 forwarding offload via macvtap device, the way
      things are now it will not end up being forwaded at all.  From
      Jason Wang

   8) Fix transmit queue selection via ndo_dfwd_start_xmit(), fixing
      things like applying NETIF_F_LLTX to the wrong device (!!) and
      eliding the proper transmit watchdog handling

   9) qlcnic driver was not updating tx statistics at all, from Manish
      Chopra"

* git://git.kernel.org/pub/scm/linux/kernel/git/davem/net:
  qlcnic: Fix ethtool statistics length calculation

  net: core: explicitly select a txq before doing l2 forwarding
  macvlan: forbid L2 fowarding offload for macvtap
  bnx2x: fix DMA unmapping of TSO split BDs
  ipv6: add link-local, sit and loopback address with INFINITY_LIFE_TIME
  bnx2x: prevent WARN during driver unload
  tipc: correctly unlink packets from deferred packet queue
  ipv6: pcpu_tstats.syncp should be initialised in ip6_vti.c
  netfilter: only warn once on wrong seqadj usage
  netfilter: nf_nat: fix access to uninitialized buffer in IRC NAT helper
  NFC: Fix target mode p2p link establishment
  iwlwifi: add new devices for 7265 series
  mac80211: move "bufferable MMPDU" check to fix AP mode scan
  mac80211_hwsim: Fix NULL pointer dereference
