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

Pull networking fixes from David Miller:

 1) Fix SKB leak in 8139cp, from Dave Jones.

 2) Fix use of *_PAGES interfaces with mlx5 firmware, from Moshe Lazar.

 3) RCU conversion of macvtap introduced two races, fixes by Eric
    Dumazet

 4) Synchronize statistic flows in bnx2x driver to prevent corruption,
    from Dmitry Kravkov

 5) Undo optimization in IP tunneling, we were using the inner IP header
    in some cases to inherit the IP ID, but that isn't correct in some
    circumstances.  From Pravin B Shelar

 6) Use correct struct size when parsing netlink attributes in
    rtnl_bridge_getlink().  From Asbjoern Sloth Toennesen

 7) Length verifications in tun_get_user() are bogus, from Weiping Pan
    and Dan Carpenter

 8) Fix bad merge resolution during 3.11 networking development in
    openvswitch, albeit a harmless one which added some unreachable
    code.  From Jesse Gross

 9) Wrong size used in flexible array allocation in openvswitch, from
    Pravin B Shelar

10) Clear out firmware capability flags the be2net driver isn't ready to
    handle yet, from Sarveshwar Bandi

11) Revert DMA mapping error checking addition to cxgb3 driver, it's
    buggy.  From Alexey Kardashevskiy

12) Fix regression in packet scheduler rate limiting when working with a
    link layer of ATM.  From Jesper Dangaard Brouer

13) Fix several errors in TCP Cubic congestion control, in particular
    overflow errors in timestamp calculations.  From Eric Dumazet and
    Van Jacobson

14) In ipv6 routing lookups, we need to backtrack if subtree traversal
    don't result in a match.  From Hannes Frederic Sowa

15) ipgre_header() returns incorrect packet offset.  Fix from Timo Teräs

16) Get "low latency" out of the new MIB counter names.  From Eliezer
    Tamir

17) State check in ndo_dflt_fdb_del() is inverted, from Sridhar
    Samudrala

18) Handle TCP Fast Open properly in netfilter conntrack, from Yuchung
    Cheng

19) Wrong memcpy length in pcan_usb driver, from Stephane Grosjean

20) Fix dealock in TIPC, from Wang Weidong and Ding Tianhong

21) call_rcu() call to destroy SCTP transport is done too early and
    might result in an oops.  From Daniel Borkmann

22) Fix races in genetlink family dumps, from Johannes Berg

23) Flags passed into macvlan by the user need to be validated properly,
    from Michael S Tsirkin

24) Fix skge build on 32-bit, from Stephen Hemminger

25) Handle malformed TCP headers properly in xt_TCPMSS, from Pablo Neira
    Ayuso

26) Fix handling of stacked vlans in vlan_dev_real_dev(), from Nikolay
    Aleksandrov

27) Eliminate MTU calculation overflows in esp{4,6}, from Daniel
    Borkmann

28) neigh_parms need to be setup before calling the ->ndo_neigh_setup()
    method.  From Veaceslav Falico

29) Kill out-of-bounds prefetch in fib_trie, from Eric Dumazet

30) Don't dereference MLD query message if the length isn't value in the
    bridge multicast code, from Linus Lüssing

31) Fix VXLAN IGMP join regression due to an inverted check, from Cong
    Wang
