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

Pull networking fixes from David Miller:

 1) nft_compat accidently truncates ethernet protocol to 8-bits, from
    Arturo Borrero.

 2) Memory leak in ip_vs_proc_conn(), from Julian Anastasov.

 3) Don't allow the space required for nftables rules to exceed the
    maximum value representable in the dlen field.  From Patrick
    McHardy.

 4) bcm63xx_enet can accidently leave interrupts permanently disabled
    due to errors in the NAPI polling exit logic.  Fix from Nicolas
    Schichan.

 5) Fix OOPSes triggerable by the ping protocol module, due to missing
    address family validations etc.  From Lorenzo Colitti.

 6) Don't use RCU locking in sleepable context in team driver, from Jiri
    Pirko.

 7) xen-netback miscalculates statistic offset pointers when reporting
    the stats to userspace.  From David Vrabel.

 8) Fix a leak of up to 256 pages per VIF destroy in xen-netaback, also
    from David Vrabel.

 9) ip_check_defrag() cannot assume that skb_network_offset(),
    particularly when it is used by the AF_PACKET fanout defrag code.
    From Alexander Drozdov.

10) gianfar driver doesn't query OF node names properly when trying to
    determine the number of hw queues available.  Fix it to explicitly
    check for OF nodes named queue-group.  From Tobias Waldekranz.

11) MID field in macb driver should be 12 bits, not 16.  From Punnaiah
    Choudary Kalluri.

12) Fix unintentional regression in traceroute due to timestamp socket
    option changes.  Empty ICMP payloads should be allowed in
    non-timestamp cases.  From Willem de Bruijn.

13) When devices are unregistered, we have to get rid of AF_PACKET
    multicast list entries that point to it via ifindex.  Fix from
    Francesco Ruggeri.
