- You can set skb->priority to values between 0 and 15 (see include/linux/pkt_sched.h) What actually happens depends on the queueing discipline that is set for the interface. The default one uses a 3 w

- This is one of the reasons for drivers to keep their Tx queues to a reasonable length. Two years ago an almost-always-sufficient Tx queue length was between 6 and 10, so most of my bus-master drivers

- Keep thinking about loud... I was thinking that a linked list would be more flexible and potentially more optimal, but checking that out is 2.5.x material for me :)

- Actually, this is not re-ordering per-se. This would be done _per-flow_ and not with packets within the same flow. i.e certain flows are more important than others and would skip FIFO queue rules. B
