Has anybody discussed adding a header with just the 3 bytes you need
*before* the IP header?
We've discussed using forms of tag switching from the beginning of the
WG but there must be an IP based reference model before we start doing
the tricks.
You can have a reference model which uses IP-in-IP plus a destination
options to carry the 3 bytes, and then have an optimization for low
speed networks like 6lowpan that sticks those bytes somewhere else as
Carsten suggested.
Architecturally, in both cases, we'd end up with the 3 bytes before the
(inner) IP header.
