Note that queue's weight do not implement priorities. The rule is
quite simple : sum up all weight of all queues connected to one pipe
and then each queue will be assigned the following bandwidth :
queuebw = totalbw * queueweight / totalweight
ALTQ does prioritize the traffic. This means that packets with high
priority are placed before lower prioritized packets in the device
output FIFO.
