Subject: Problematic commits in the ipsec tree

Hannes,

I have two problematic commits from you in the ipsec tree. The first one is:

commit 0ea9d5e3e (xfrm: introduce helper for safe determination of mtu)

This breakes pmtu discovery for IPv4 because now we use the device mtu
instead of the reduced IPsec mtu in xfrm4_tunnel_check_size() if a IPv4
socket is at the skb.

The second is:

commit 844d48746 (xfrm: choose protocol family by skb protocol)

This breaks pmtu discovery for IPv6 too because skb->protocol can be null
in __xfrm6_output().

We need a solution soon, or I have to revert or remove these commits from
the ipsec tree.
