[c-nsp] Interface Queues

[Rodney Dunn]

The tx-queue-limit I always saw was for the 75xx
due to the QA asic forwarding. It set the memd txacc
queues.

For the traditional boxes it's hold-queue out or tx ring.
The tx ring is the fifo queue to the device driver.

The hold-queue is where we back packets up when the tx
ring is congested. That's if there isn't a QOS policy
applied at which point you have queue-limit under the
individual classes.

ATM is a bit more complex with per VC queues. I'm not sure
if they have a tx-queue-limit concept.
