Hmm, so if I understand you correctly you're saying that the QUANTUM
in each SFQ should be proportional to the bandwidth allocated to that
pool.  As per the documents I've read, this must also be >= the
maximum packet size.

I /could/ do that but that'd mean that I have to scan all the pools
beforehand and figure out the weights for each pool, since the weights
are relative.  I was hoping that htb.init would do that for me
automatically :)

Another question: wouldn't the QUANTUM only affect the sharing within
a specific pool?  Or would it have an impact at the global level
(inter-pool) bandwidth allocation too?
