Pull networking fixes from David Miller:
 "I've been traveling so this accumulates more than week or so of bug
  fixing.  It perhaps looks a little worse than it really is.

   1) Fix deadlock in ath10k driver, from Ben Greear.

   2) Increase scan timeout in iwlwifi, from Luca Coelho.

   3) Unbreak STP by properly reinjecting STP packets back into the
      stack.  Regression fix from Ido Schimmel.

   4) Mediatek driver fixes (missing malloc failure checks, leaking of
      scratch memory, wrong indexing when mapping TX buffers, etc.) from
      John Crispin.

   5) Fix endianness bug in icmpv6_err() handler, from Hannes Frederic
      Sowa.

   6) Fix hashing of flows in UDP in the ruseport case, from Xuemin Su.

   7) Fix netlink notifications in ovs for tunnels, delete link messages
      are never emitted because of how the device registry state is
      handled.  From Nicolas Dichtel.

   8) Conntrack module leaks kmemcache on unload, from Florian Westphal.

   9) Prevent endless jump loops in nft rules, from Liping Zhang and
      Pablo Neira Ayuso.

  10) Not early enough spinlock initialization in mlx4, from Eric
      Dumazet.

  11) Bind refcount leak in act_ipt, from Cong WANG.

  12) Missing RCU locking in HTB scheduler, from Florian Westphal.

  13) Several small MACSEC bug fixes from Sabrina Dubroca (missing RCU
      barrier, using heap for SG and IV, and erroneous use of async flag
      when allocating AEAD conext.)

  14) RCU handling fix in TIPC, from Ying Xue.

  15) Pass correct protocol down into ipv4_{update_pmtu,redirect}() in
      SIT driver, from Simon Horman.

  16) Socket timer deadlock fix in TIPC from Jon Paul Maloy.

  17) Fix potential deadlock in team enslave, from Ido Schimmel.

  18) Memory leak in KCM procfs handling, from Jiri Slaby.

  19) ESN generation fix in ipv4 ESP, from Herbert Xu.

  20) Fix GFP_KERNEL allocations with locks held in act_ife, from Cong
      WANG.

  21) Use after free in netem, from Eric Dumazet.

  22) Uninitialized last assert time in multicast router code, from Tom
      Goff.

  23) Skip raw sockets in sock_diag destruction broadcast, from Willem
      de Bruijn.

  24) Fix link status reporting in thunderx, from Sunil Goutham.

  25) Limit resegmentation of retransmit queue so that we do not
      retransmit too large GSO frames.  From Eric Dumazet.

  26) Delay bpf program release after grace period, from Daniel
      Borkmann"
