WFQ queue limit

[Luca Liberti <xliberti@tin.it>]

Hello everibody
   someone knows how to set queue limit of packet scheduler in links?

I tryed with method, 
          Simulator queue-limit 
it sets the variable limit_ in class Queue. Unfortunately it doesn't  work. 

This function works well with DropTail queue, but hasn't  any effect on
other queues like: SFQ, FQ.

Thanks in advance
   Luca
