Pull networking fixes from David Miller:

 1) Don't corrupt xfrm_interface parms before validation, from Nicolas
    Dichtel.

 2) Revert use of usb-wakeup in btusb, from Mario Limonciello.

 3) Block ipv6 packets in bridge netfilter if ipv6 is disabled, from
    Leonardo Bras.

 4) IPS_OFFLOAD not honored in ctnetlink, from Pablo Neira Ayuso.
