The weighted values control relative bandwidth for each queue of the
four queues. Each byte represents the proportional weight out
of 100 for a queue. The sum of these bytes must equal to 100.
For example, if 2 queues are used, and the relative
weights (or priorities) are 90 and 10, then acQosQueueWeights should be
set to '\0x5A\0x0A\0x00\0x00'.
