Pull networking fixes from David Miller:

 1) Fix BPF handling of branch offset adjustmnets on backjumps, from
    Daniel Borkmann.

 2) Make sure selinux knows about SOCK_DESTROY netlink messages, from
    Lorenzo Colitti.

 3) Fix openvswitch tunnel mtu regression, from David Wragg.

 4) Fix ICMP handling of TCP sockets in syn_recv state, from Eric
    Dumazet.

 5) Fix SCTP user hmacid byte ordering bug, from Xin Long.

 6) Fix recursive locking in ipv6 addrconf, from Subash Abhinov
    Kasiviswanathan.
