- For further reflection: Have you considered the case where the rate table has already been considered on some link speed in user space and then somewhere post-config the physical link speed changes? This would happen in the case where ethernet AN is involved and the partner makes some changes (use ethtool).

I've thought about this a couple of times, scaling the virtual clock rate should be enough for "simple" qdiscs like TBF or HTB, which have a linear relation between time and bandwidth. I haven't really thought about the effects on HFSC yet, on a small scale the relation is non-linear.
Does HFSC not depend on bandwith? How is rate control achieved?
But this is a different problem from trying to accomodate for link-layer overhead.
Yes it is different issue. cheers, jamal
