Re: MQC priority inside class-default

The shape peak is for the class-default class dictated by the task. Nothing
to do with VoIP class. The confusion was whether to give priority out of
interface bandwidth or out of shaped bandwdith.

For eg: If Interface BW = 512K,

1st solution says, give 64kbps priority to VoIP and the remaining 448kbps to
be shaped to 256kbps peak.
2nd solution says, shape all traffic to peak value of 256kbps first and then
reserve 64kbps to VoIP traffic.

In both cases, VoIP was given priority but 1st solution gave (64 + 256) =
320kbps of total BW for data traffic; whereas 2nd solution gave 256kbps of
total BW for data traffic. If no other clues are given in the task, I would
go with second solution.
