    Pull networking updates from David Miller:
     "This is a re-do of the net-next pull request for the current merge
      window.  The only difference from the one I made the other day is that
      this has Eliezer's interface renames and the timeout handling changes
      made based upon your feedback, as well as a few bug fixes that have
      trickeled in.
       1) Low latency device polling, eliminating the cost of interrupt
          handling and context switches.  Allows direct polling of a network
          device from socket operations, such as recvmsg() and poll().
          Currently ixgbe, mlx4, and bnx2x support this feature.
          Full high level description, performance numbers, and design in
          commit 0a4db187 ("Merge branch 'll_poll'")
          From Eliezer Tamir.
       2) With the routing cache removed, ip_check_mc_rcu() gets exercised
          more than ever before in the case where we have lots of multicast
          addresses.  Use a hash table instead of a simple linked list, from
          Eric Dumazet.
       3) Add driver for Atheros CQA98xx 802.11ac wireless devices, from
          Bartosz Markowski, Janusz Dziedzic, Kalle Valo, Marek Kwaczynski,
          Marek Puzyniak, Michal Kazior, and Sujith Manoharan.
       4) Support reporting the TUN device persist flag to userspace, from
          Pavel Emelyanov.
       5) Allow controlling network device VF link state using netlink, from
          Rony Efraim.
       6) Support GRE tunneling in openvswitch, from Pravin B Shelar.
       7) Adjust SOCK_MIN_RCVBUF and SOCK_MIN_SNDBUF for modern times, from
          Daniel Borkmann and Eric Dumazet.
       8) Allow controlling of TCP quickack behavior on a per-route basis,
          from Cong Wang.
       9) Several bug fixes and improvements to vxlan from Stephen
          Hemminger, Pravin B Shelar, and Mike Rapoport.  In particular,
          support receiving on multiple UDP ports.
      10) Major cleanups, particular in the area of debugging and cookie
          lifetime handline, to the SCTP protocol code.  From Daniel
      11) Allow packets to cross network namespaces when traversing tunnel
          devices.  From Nicolas Dichtel.
      12) Allow monitoring netlink traffic via AF_PACKET sockets, in a
          manner akin to how we monitor real network traffic via ptype_all.
          From Daniel Borkmann.
      13) Several bug fixes and improvements for the new alx device driver,
          from Johannes Berg.
      14) Fix scalability issues in the netem packet scheduler's time queue,
          by using an rbtree.  From Eric Dumazet.
      15) Several bug fixes in TCP loss recovery handling, from Yuchung
      16) Add support for GSO segmentation of MPLS packets, from Simon
      17) Make network notifiers have a real data type for the opaque
          pointer that's passed into them.  Use this to properly handle
          network device flag changes in arp_netdev_event().  From Jiri
          Pirko and Timo Teräs.
      18) Convert several drivers over to module_pci_driver(), from Peter
      19) tcp_fixup_rcvbuf() can loop 500 times over loopback, just use a
          O(1) calculation instead.  From Eric Dumazet.
      20) Support setting of explicit tunnel peer addresses in ipv6, just
          like ipv4.  From Nicolas Dichtel.
      21) Protect x86 BPF JIT against spraying attacks, from Eric Dumazet.
      22) Prevent a single high rate flow from overruning an individual cpu
          during RX packet processing via selective flow shedding.  From
          Willem de Bruijn.
      23) Don't use spinlocks in TCP md5 signing fast paths, from Eric
      24) Don't just drop GSO packets which are above the TBF scheduler's
          burst limit, chop them up so they are in-bounds instead.  Also
          from Eric Dumazet.
      25) VLAN offloads are missed when configured on top of a bridge, fix
          from Vlad Yasevich.
      26) Support IPV6 in ping sockets.  From Lorenzo Colitti.
      27) Receive flow steering targets should be updated at poll() time
          too, from David Majnemer.
      28) Fix several corner case regressions in PMTU/redirect handling due
          to the routing cache removal, from Timo Teräs.
      29) We have to be mindful of ipv4 mapped ipv6 sockets in
          upd_v6_push_pending_frames().  From Hannes Frederic Sowa.
      30) Fix L2TP sequence number handling bugs, from James Chapman."
