Almost - by using a mask specifier, you are creating dynamic queues.  A
new queue will be instantiated for each matching flow, with the same
parameters as the original queue.  Yes, this is a way of ensuring that
each flow will fairly share the bandwidth with the other flows in the
same queue.  You could still have different queues on the same pipe
with different weights.

The FreeBSD man page for ipfw is useful, if too long.
