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 rather I mean that it is costly.
We would need to change the 'qdisc' member of struct netdev
into an array of qdiscs. How to do that efficiently so that
other devices do not eat the space cost assosciated with
this is unclear.
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
with pre-classification by the NIC would require multiple input queues
though ..
