Pull networking fixes from David Miller:

 1) Bluetooth pairing fixes from Johan Hedberg.

 2) ieee80211_send_auth() doesn't allocate enough tail room for the SKB,
    from Max Stepanov.

 3) New iwlwifi chip IDs, from Oren Givon.

 4) bnx2x driver reads wrong PCI config space MSI register, from Yijing
    Wang.

 5) IPV6 MLD Query validation isn't strong enough, from Hangbin Liu.

 6) Fix double SKB free in openvswitch, from Andy Zhou.

 7) Fix sk_dst_set() being racey with UDP sockets, leading to strange
    crashes, from Eric Dumazet.

 8) Interpret the NAPI budget correctly in the new systemport driver,
    from Florian Fainelli.

 9) VLAN code frees percpu stats in the wrong place, leading to crashes
    in the get stats handler.  From Eric Dumazet.

10) TCP sockets doing a repair can crash with a divide by zero, because
    we invoke tcp_push() with an MSS value of zero.  Just skip that part
    of the sendmsg paths in repair mode.  From Christoph Paasch.

11) IRQ affinity bug fixes in mlx4 driver from Amir Vadai.

12) Don't ignore path MTU icmp messages with a zero mtu, machines out
    there still spit them out, and all of our per-protocol handlers for
    PMTU can cope with it just fine.  From Edward Allcutt.

13) Some NETDEV_CHANGE notifier invocations were not passing in the
    correct kind of cookie as the argument, from Loic Prylli.

14) Fix crashes in long multicast/broadcast reassembly, from Jon Paul
    Maloy.

15) ip_tunnel_lookup() doesn't interpret wildcard keys correctly, fix
    from Dmitry Popov.

16) Fix skb->sk assigned without taking a reference to 'sk' in
    appletalk, from Andrey Utkin.

17) Fix some info leaks in ULP event signalling to userspace in SCTP,
    from Daniel Borkmann.

18) Fix deadlocks in HSO driver, from Olivier Sobrie.
