====================
pull request (net): ipsec 2017-03-06

1) Fix lockdep splat on xfrm policy subsystem initialization.
   From Florian Westphal.

2) When using socket policies on IPv4-mapped IPv6 addresses,
   we access the flow informations of the wrong address family
   what leads to an out of bounds access. Fix this by using
   the family we get with the dst_entry, like we do it for the
   standard policy lookup.

3) vti6 can report a PMTU below IPV6_MIN_MTU. Fix this by
   adding a check for that before sending a ICMPV6_PKT_TOOBIG
   message.

Please pull or let me know if there are problems.
