If you use the command wrr-queue bandwidth 1 2 3 4 its not 25% for each
queue.
Queue 1 would be 1/(1+2+3+4) = 1/10 = 10%
Queue 2 would be 2/(1+2+3+4) = 2/10 = 20%
Queue 3 would be 3/(1+2+3+4) = 3/10 = 30%
Queue 4 would be 4/(1+2+3+4) = 4/10 = 40%
The default if you dont use this command is 25% for each queue, and of
course this will change if you activate the priority queue.
