Dummynet queue reconfiguration

[Martin Petraschek]

Hi!

We are planning to use dummynet for bandwidth control and are 
very happy with the abilities of dummynet so far, but recently we ran 
into a problem we cannot solve:

The man page of ipfw says, that the "ipfw queue" command can be 
used to create OR MODIFY an existing queue. But when I issue a 
command like

ipfw queue 6 config weight 50 pipe 5

the weight of the queue is not changed. Only if I first delete the 
queue with "ipfw queue delete" and then recreate it with the above 
command, the weight is changed as expected. 

Is it not possibly to reconfigure the queue dynamically or am I 
missing something?

Thank you very much,

Martin
