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

Pull networking fixes from David Miller:
 "The pull requests are getting smaller, that's progress I suppose :-)

   1) Fix infinite loop in CIPSO option parsing, from Yujuan Qi.

   2) Fix remote checksum handling in VXLAN and GUE tunneling drivers,
      from Koichiro Den.

   3) Missing u64_stats_init() calls in several drivers, from Florian
      Fainelli.

   4) TCP can set the congestion window to an invalid ssthresh value
      after congestion window reductions, from Yuchung Cheng.

   5) Fix BPF jit branch generation on s390, from Daniel Borkmann.

   6) Correct MIPS ebpf JIT merge, from David Daney.

   7) Correct byte order test in BPF test_verifier.c, from Daniel
      Borkmann.

   8) Fix various crashes and leaks in ASIX driver, from Dean Jenkins.

   9) Handle SCTP checksums properly in mlx4 driver, from Davide
      Caratti.

  10) We can potentially enter tcp_connect() with a cached route
      already, due to fastopen, so we have to explicitly invalidate it.

  11) skb_warn_bad_offload() can bark in legitimate situations, fix from
      Willem de Bruijn"
