    Pull networking updates from David Miller:
     "Highlights:
    
       1) Support more Realtek wireless chips, from Jes Sorenson.
    
       2) New BPF types for per-cpu hash and arrap maps, from Alexei
          Starovoitov.
    
       3) Make several TCP sysctls per-namespace, from Nikolay Borisov.
    
       4) Allow the use of SO_REUSEPORT in order to do per-thread processing
       of incoming TCP/UDP connections.  The muxing can be done using a
       BPF program which hashes the incoming packet.  From Craig Gallek.
    
       5) Add a multiplexer for TCP streams, to provide a messaged based
          interface.  BPF programs can be used to determine the message
          boundaries.  From Tom Herbert.
    
       6) Add 802.1AE MACSEC support, from Sabrina Dubroca.
    
       7) Avoid factorial complexity when taking down an inetdev interface
          with lots of configured addresses.  We were doing things like
          traversing the entire address less for each address removed, and
          flushing the entire netfilter conntrack table for every address as
          well.
    
       8) Add and use SKB bulk free infrastructure, from Jesper Brouer.
    
       9) Allow offloading u32 classifiers to hardware, and implement for
          ixgbe, from John Fastabend.
    
      10) Allow configuring IRQ coalescing parameters on a per-queue basis,
          from Kan Liang.
    
      11) Extend ethtool so that larger link mode masks can be supported.
          From David Decotigny.
    
      12) Introduce devlink, which can be used to configure port link types
          (ethernet vs Infiniband, etc.), port splitting, and switch device
          level attributes as a whole.  From Jiri Pirko.
    
      13) Hardware offload support for flower classifiers, from Amir Vadai.
    
      14) Add "Local Checksum Offload".  Basically, for a tunneled packet
          the checksum of the outer header is 'constant' (because with the
          checksum field filled into the inner protocol header, the payload
          of the outer frame checksums to 'zero'), and we can take advantage
          of that in various ways.  From Edward Cree"
