[altq 132] New bug in CBQ code

[Fulvio Risso <F.Risso@cs.ucl.ac.uk>]

Hello.
I'm experimenting the same bug as pointed out by George Uhl.
I have a lot of traffic that exceeds the rate allocated to a UDP class, and a certain point that class is not able to send anything.
The queue size is constantly 30 packets and all incoming packets are dropped.

Interestingly:
- all the other classes are able to send
- this class has average idle to a negative value, that never changes (so it becomes never > 0).

Any idea?
Suspension time wrong (i.e. the clas is suspended for some hours)?

Cheers,
