Pull networking fixes from David Miller:

 1) If the timing is wrong we can indefinitely stop generating new ipv6
    temporary addresses, from Marcus Huewe.

 2) Don't double free per-cpu stats in ipv6 SIT tunnel driver, from Cong
    Wang.

 3) Put protections in place so that AF_PACKET is not able to submit
    packets which don't even have a link level header to drivers. From
    Willem de Bruijn.

 4) Fix memory leaks in ipv4 and ipv6 multicast code, from Hangbin Liu.

 5) Don't use udp_ioctl() in l2tp code, UDP version expects a UDP socket
    and that doesn't go over very well when it is passed an L2TP one.
    Fix from Eric Dumazet.

 6) Don't crash on NULL pointer in phy_attach_direct(), from Florian
    Fainelli.
