Any smart queuing/scheduling etc. made by driver, will render useless while network stack provides single Tx queue. The packet schedulers already have multiple queues, why isn't the packet scheduling framework sufficient? Who cares if there is a single TX "delivery point" to the driver, as long as the driver knows how to differentiate queues.
