[j-nsp] QoS when there is no congestion

[Tim St. Pierre]

If you have some lower bandwidth links, you may still see a latency 
improvement if you implement QoS.

The important thing here is in your output queues, as strict priority 
will see voice traffic serviced first.  Even if nothing is ever dropped, 
going out the queue first keeps latency low.
