    Pull networking updates from David Miller:
     "Most notable changes in here:
    
       1) By far the biggest accomplishment, thanks to a large range of
          contributors, is the addition of multi-send for transmit.  This is
          the result of discussions back in Chicago, and the hard work of
          several individuals.
    
          Now, when the ->ndo_start_xmit() method of a driver sees
          skb->xmit_more as true, it can choose to defer the doorbell
          telling the driver to start processing the new TX queue entires.
    
          skb->xmit_more means that the generic networking is guaranteed to
          call the driver immediately with another SKB to send.
    
          There is logic added to the qdisc layer to dequeue multiple
          packets at a time, and the handling mis-predicted offloads in
          software is now done with no locks held.
    
          Finally, pktgen is extended to have a "burst" parameter that can
          be used to test a multi-send implementation.
    
          Several drivers have xmit_more support: i40e, igb, ixgbe, mlx4,
          virtio_net
    
          Adding support is almost trivial, so export more drivers to
          support this optimization soon.
    
          I want to thank, in no particular or implied order, Jesper
          Dangaard Brouer, Eric Dumazet, Alexander Duyck, Tom Herbert, Jamal
          Hadi Salim, John Fastabend, Florian Westphal, Daniel Borkmann,
          David Tat, Hannes Frederic Sowa, and Rusty Russell.
    
       2) PTP and timestamping support in bnx2x, from Michal Kalderon.
    
       3) Allow adjusting the rx_copybreak threshold for a driver via
          ethtool, and add rx_copybreak support to enic driver.  From
          Govindarajulu Varadarajan.
    
       4) Significant enhancements to the generic PHY layer and the bcm7xxx
          driver in particular (EEE support, auto power down, etc.) from
          Florian Fainelli.
    
       5) Allow raw buffers to be used for flow dissection, allowing drivers
          to determine the optimal "linear pull" size for devices that DMA
          into pools of pages.  The objective is to get exactly the
          necessary amount of headers into the linear SKB area pre-pulled,
          but no more.  The new interface drivers use is eth_get_headlen().
          From WANG Cong, with driver conversions (several had their own
          by-hand duplicated implementations) by Alexander Duyck and Eric
          Dumazet.
    
       6) Support checksumming more smoothly and efficiently for
          encapsulations, and add "foo over UDP" facility.  From Tom
          Herbert.
    
       7) Add Broadcom SF2 switch driver to DSA layer, from Florian
          Fainelli.
    
       8) eBPF now can load programs via a system call and has an extensive
          testsuite.  Alexei Starovoitov and Daniel Borkmann.
    
       9) Major overhaul of the packet scheduler to use RCU in several major
          areas such as the classifiers and rate estimators.  From John
          Fastabend.
    
      10) Add driver for Intel FM10000 Ethernet Switch, from Alexander
          Duyck.
    
      11) Rearrange TCP_SKB_CB() to reduce cache line misses, from Eric
          Dumazet.
    
      12) Add Datacenter TCP congestion control algorithm support, From
          Florian Westphal.
    
      13) Reorganize sk_buff so that __copy_skb_header() is significantly
          faster.  From Eric Dumazet"
