Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net

Pull networking fixes from David Miller:
 "A bit has accumulated, but it's been a week or so since my last batch
  of post-merge-window fixes, so...

   1) Missing module license in netfilter reject module, from Pablo.
      Lots of people ran into this.

   2) Off by one in mac80211 baserate calculation, from Karl Beldan.

   3) Fix incorrect return value from ax88179_178a driver's set_mac_addr
      op, which broke use of it with bonding.  From Ian Morgan.

   4) Checking of skb_gso_segment()'s return value was not all
      encompassing, it can return an SKB pointer, a pointer error, or
      NULL.  Fix from Florian Westphal.

      This is crummy, and longer term will be fixed to just return error
      pointers or a real SKB.

   6) Encapsulation offloads not being handled by
      skb_gso_transport_seglen().  From Florian Westphal.

   7) Fix deadlock in TIPC stack, from Ying Xue.

   8) Fix performance regression from using rhashtable for netlink
      sockets.  The problem was the synchronize_net() invoked for every
      socket destroy.  From Thomas Graf.

   9) Fix bug in eBPF verifier, and remove the strong dependency of BPF
      on NET.  From Alexei Starovoitov.

  10) In qdisc_create(), use the correct interface to allocate
      ->cpu_bstats, otherwise the u64_stats_sync member isn't
      initialized properly.  From Sabrina Dubroca.

  11) Off by one in ip_set_nfnl_get_byindex(), from Dan Carpenter.

  12) nf_tables_newchain() was erroneously expecting error pointers from
      netdev_alloc_pcpu_stats().  It only returna a valid pointer or
      NULL.  From Sabrina Dubroca.

  13) Fix use-after-free in _decode_session6(), from Li RongQing.

  14) When we set the TX flow hash on a socket, we mistakenly do so
      before we've nailed down the final source port.  Move the setting
      deeper to fix this.  From Sathya Perla.

  15) NAPI budget accounting in amd-xgbe driver was counting descriptors
      instead of full packets, fix from Thomas Lendacky.

  16) Fix total_data_buflen calculation in hyperv driver, from Haiyang
      Zhang.

  17) Fix bcma driver build with OF_ADDRESS disabled, from Hauke
      Mehrtens.

  18) Fix mis-use of per-cpu memory in TCP md5 code.  The problem is
      that something that ends up being vmalloc memory can't be passed
      to the crypto hash routines via scatter-gather lists.  From Eric
      Dumazet.

  19) Fix regression in promiscuous mode enabling in cdc-ether, from
      Olivier Blin.

  20) Bucket eviction and frag entry killing can race with eachother,
      causing an unlink of the object from the wrong list.  Fix from
      Nikolay Aleksandrov.

  21) Missing initialization of spinlock in cxgb4 driver, from Anish
      Bhatt.

  22) Do not cache ipv4 routing failures, otherwise if the sysctl for
      forwarding is subsequently enabled this won't be seen.  From
      Nicolas Cavallari"
