Thank you for this answer.
Alex is trying to make the lowpan code for the Linux kernel more flexible,
and the question of whether we need to include a way to use different MTUs on
a per-destination basis has come up, and we had no clear answer.
We now know that this is physically possible; we don't know if chipsets will
implement this, or whether it SHOULD be possible.
This is now a technical policy question for 6lo, in my opinion.
