Thanks for the patch guys, this is really interesting.

Although the document only talks about ESP, as far as I can see
the encapsulation can be applied to AH/IPComp just as well.
So how about moving this stuff to the generic xfrm_input/xfrm_output
functions?
Also, if you're going to do cross-family transforms, it should be
done for both BEET and plain tunnel-mode.
Cheers,
