I was wondering if there was any support for handling ethernet devices that support multiple RX/TX queues to provide QoS. If so any pointers would be great. thanks - kumar

The question was very ambigous. What is it that Kumar is looking for? Is it 802.1p, IP level etc? cheers, jamal

I guess, Kumar is asking for support for several Tx queues with different priorities. One need to start/stop these queues separately. This is dictated by presense of different priorities on physical

Yes, I do. So far, I have hardware related parts working. I rely on skb->priority to determine traffic class and select proper queue. All this worth nothing if one can't do separate queues. qdisc ass

Who marks the skb->priority? Is that the default mark as per TOS? I think the VLAN code marks it as well. I dont think we should put intelligence at the driver level. We can have drivers configured v

I don't care. It should not be driver's business. Actually, it is TOS. AFAIK, application supposed to do setsockoption(SO_PRIORITY) on its socket so set priority. Agree about intelligence. Driver sho

FWIW the madwifi net80211 layer parses TOS to calculate priority and sticks it in the skb. It also calculates the WME AC to form the QoS frame matter. This is then handed to drivers below. The Athero

Sam, I think, to use skb->priority is more proper then parse TOS. Several points for this: 1. by default, IP code do it for you - it sets skb->priority equal to TOS; 2. stack may have better idea of

If you have several MAC-layer queues, then do you have another set of MAC-layer scheduling? If so, how do you select the algorithm? I suggest this can of worms requires further thought before we end

A mapping is being suggested. Qdiscs handle the queueing. Send it to the driver/MAC layer with instructions of which queue it goes on. Refer to the thread earlier; i think the mapping is pretty much

this is not very important. From one side, it seems like bug in routing code. - From another side, 802.11 was supposed for link ends only. It is not supposed to appear in the middle of routers chain.

Problem is, I don't know how driver can dictate what qdiscs should be attached to it. AFAIK, it is under 'tc' control. What I suggest, is to provide some API for driver to configure its qdiscs. There
