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

Pull networking fixes from David Miller:

 1) Fix handling of initial STATE message in TIPC, from Jon Paul Maloy.

 2) Fix stats handling in bcm_sysport_get_stats(), from Florian
    Fainelli.

 3) Reject 16777215 VNI value in geneve_validate(), from Girish
    Moodalbail.

 4) Fix initial IGMP sysctl setting regression, from Nikolay Borisov.

 5) Once a UFO fragmented frame is treated as UFO, we should continue
    doing so. Likewise once a frame has been segmented, we should
    continue doing that and not try to convert it to a UFO frame. From
    Willem de Bruijn.

 6) Test the AF_PACKET RX/TX ring pg_vec state under the socket lock to
    prevent races. From Willem de Bruijn.

  packet: fix tp_reserve race in packet_set_ring
