avpkt is one of the parameters used to evaluate the maxidle parameter 
for a cbq class.
maxidle can be seen as the maximum credit that a class can reach when 
being underlimit for a period of time
So the higher maxidle is, the more packets in burst the class may send 
when switching  from underlimit to overlimit.
