Pull networking fixes from David Miller:

 1) Fix RCU locking in xfrm_local_error(), from Taehee Yoo.

 2) Fix return value assignments and thus error checking in
    iwl_mvm_start_ap_ibss(), from Johannes Berg.

 3) Don't count header length twice in vti4, from Stefano Brivio.

 4) Fix deadlock in rt6_age_examine_exception, from Eric Dumazet.

 5) Fix out-of-bounds access in nf_sk_lookup_slow{v4,v6}() from Subash
    Abhinov.

 6) Check nladdr size in netlink_connect(), from Alexander Potapenko.

 7) VF representor SQ numbers are 32 not 16 bits, in mlx5 driver, from
    Or Gerlitz.

 8) Out of bounds read in skb_network_protocol(), from Eric Dumazet.

 9) r8169 driver sets driver data pointer after register_netdev() which
    is too late. Fix from Heiner Kallweit.

10) Fix memory leak in mlx4 driver, from Moshe Shemesh.

11) The multi-VLAN decap fix added a regression when dealing with device
    that lack a MAC header, such as tun. Fix from Toshiaki Makita.

12) Fix integer overflow in dynamic interrupt coalescing code. From Tal
    Gilboa.

13) Use after free in vrf code, from David Ahern.

14) IPV6 route leak between VRFs fix, also from David Ahern.
