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

Pull networking fixes from David Miller:

 1) The bnx2x can hang if you give it a GSO packet with a segment size
    which is too big for the hardware, detect and drop in this case.
    From Daniel Axtens.

 2) Fix some overflows and pointer leaks in xtables, from Dmitry Vyukov.

 3) Missing RCU locking in igmp, from Eric Dumazet.

 4) Fix RX checksum handling on r8152, it can only checksum UDP and TCP
    packets. From Hayes Wang.

 5) Minor pacing tweak to TCP BBR congestion control, from Neal
    Cardwell.

 6) Missing RCU annotations in cls_u32, from Paolo Abeni.
