Dummynet dynamically assigned bandwidth

[Martes Wigglesworth]

I have had a problem getting dynamic bandwidth assigned while hosts are
still online. I thought that when a dynamic queue has no packets, hence
the pipe show displays 0 0 in between used and the last column, the
queue should disappear, allowing for that segment of bandwidth to be
utilized fully again. I have not seen this type of functionality, and
would like help to get a better understanding of it.

Example:

pipe 1 config bw 128Kbit/s
queue 1 config pipe 1 config mask dst-ip 0xffffffff
queue 1 ip from any to ${int_net} in recv ${ext_dev}

Result:
if ext_net={ 192.168.1.0/24}, and 8 hosts are online, then the queues
remain even when there is no traffic on that queue.  Aren't the unused
queues supposed to disappear so that the other hosts may use the
difference?

Please help. I have been struggling with this for a while.
