Since I re-read Pascal's answer (in the light of my "day"), I now see why it
can not go into to the outer IP header, because we didn't not plan for it.
I thought that in 8138, that if we didn't need an outer IPIP, that we just
used 6loHC (rfc6282... https://tools.ietf.org/html/rfc6282#section-3.2.1)
If we can agree that this is the way, then I think we also need to agree that
certain AFxx would be assigned to available bandwidth, and not cause 6top to
allocate any additional bandwidth. This does not really fit "AF" Diffserv in
some ways (which in some ways to buffer/delay rather than drop...).
