I understand, this schema will probably work perfectly
Sorry, I read my emails in a LIFO manner - typically that works well
with last email in thread covering all the previous, but occasionally
something is left over.

If its about outgoing traffic, shouldn't a prio-qdisc as root qdisc do
just fine? skb->priority can be used to select a queue. Incoming traffic

Agreed. The ipw2200 card provides 4 hardware queues for QoS. But current
network stack only supports one Tx queue.
This is actually difficult to implement support for.
Well, not difficult, but rath
