[c-nsp] CBWFQ/PQ Support on 6500/SUP720-3BXL

[Zahid Hassan]

Many thanks for this David.

Yes, the "priority" and as well as the "bandwidth" command doesn't
seems to be supported in either ingress or egress direction.

I am thinking of configuring "wrr-queues" and I don't know 
if I can at all match on EXP bits. 

Does anyone know how to match on EXP bits within a wrr-queue ?


Thanks in advance.
