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

Pull networking fixes from David Miller:

 1) Fix refcounting wrt timers which hold onto inet6 address objects,
    from Xin Long.

 2) Fix an ancient bug in wireless wext ioctls, from Johannes Berg.

 3) Firmware handling fixes in brcm80211 driver, from Arend Van Spriel.

 4) Several mlx5 driver fixes (firmware readiness, timestamp cap
    reporting, devlink command validity checking, tc offloading, etc.)
    From Eli Cohen, Maor Dickman, Chris Mi, and Or Gerlitz.

 5) Fix dst leak in IP/IP6 tunnels, from Haishuang Yan.

 6) Fix dst refcount bug in decnet, from Wei Wang.

 7) Netdev can be double freed in register_vlan_device(). Fix from Gao
    Feng.

 8) Don't allow object to be destroyed while it is being dumped in SCTP,
    from Xin Long.

 9) Fix dpaa_eth build when modular, from Madalin Bucur.

10) Fix throw route leaks, from Serhey Popovych.

11) IFLA_GROUP missing from if_nlmsg_size() and ifla_policy[] table,
    also from Serhey Popovych.

12) Fix premature TX SKB free in stmmac, from Niklas Cassel.
