It would be nice to have support for HFSC as well, which unfortunately
needs to be done in the kernel since it doesn't use rate tables.
What about qdiscs like SFQ (which uses the packet size in quantum
calculations)? I guess it would make sense to use the wire-length
there as well.

Didnt even think of that ;-> 
Is it getting too complicated? 

The code wouldn't be very complicated, it just adds some overhead. If
you do something like I described in my previous mail the overhead for
people not using it would be an additional pointer test before reading
skb->len. I guess we could also make it a compile time option.
I personally think this is something that really improves our quality
of implementation, after all, its "wire" resources qdiscs are meant
to manage.

BTW, I forgot to mention one thing on the bandwidth issue is we could do
is send netlink events on link speed changes too; some listener
somewhere would then do the adjustment.

See the mail I just wrote :)
