[ns] how to get ifqueue length

[Usman Ashraf]

Dear all,
I am simulating a wired-cum-wireless scenario. To get the queue lengths at any mobile node, I can simply call the ifqueue->PriQ->DropTail->length from any place in the routing layer and it works. However when I do the same for the gateway node, I get a Zero Queue length. Can anyone kindly explain how to get the queue length for gaetway nodes a the routing layer.
 
regards.
