I think you got me wrong, the whole point of this qdisc
is to prioritize which means that we cannot dequeue from
prio 1 as long as the queue in prio 0 is not empty. 

If you have no traffic at all for prio=0 and prio=1 then
the best solution is to replace the qdisc on the device
with a simple fifo.
