Pull more networking updates from David Miller:

 1) If a VXLAN interface is created with no groups, we can crash on
    reception of packets.  Fix from Mike Rapoport.

 2) Missing includes in CPTS driver, from Alexei Starovoitov.

 3) Fix string validations in isdnloop driver, from YOSHIFUJI Hideaki
    and Dan Carpenter.

 4) Missing irq.h include in bnxw2x, enic, and qlcnic drivers.  From
    Josh Boyer.

 5) AF_PACKET transmit doesn't statistically count TX drops, from Daniel
    Borkmann.

 6) Byte-Queue-Limit enabled drivers aren't handled properly in
    AF_PACKET transmit path, also from Daniel Borkmann.

    Same problem exists in pktgen, and Daniel fixed it there too.

 7) Fix resource leaks in driver probe error paths of new sxgbe driver,
    from Francois Romieu.

 8) Truesize of SKBs can gradually get more and more corrupted in NAPI
    packet recycling path, fix from Eric Dumazet.

 9) Fix uniprocessor netfilter build, from Florian Westphal.  In the
    longer term we should perhaps try to find a way for ARRAY_SIZE() to
    work even with zero sized array elements.

10) Fix crash in netfilter conntrack extensions due to mis-estimation of
    required extension space.  From Andrey Vagin.

11) Since we commit table rule updates before trying to copy the
    counters back to userspace (it's the last action we perform), we
    really can't signal the user copy with an error as we are beyond the
    point from which we can unwind everything.  This causes all kinds of
    use after free crashes and other mysterious behavior.

    From Thomas Graf.

12) Restore previous behvaior of div/mod by zero in BPF filter
    processing.  From Daniel Borkmann.

* git://git.kernel.org/pub/scm/linux/kernel/git/davem/net: (38 commits)
  net: sctp: wake up all assocs if sndbuf policy is per socket
