XFRM wants to work with protocol stacking at the protocol level (ie. things
within ipv4, or ipv6).

We could tweak it to do this, but I advise against this initially because
this way we can stick the MPLS stack more simply into 2.4.x if we wanted
to (and I certainly might want to do that).

After we're done, and did a 2.4.x backport if desired, we can look into
using XFRM.  But I don't advise this now.
