Determines the weight factor W of the queue at the WFQ
multiplexer input to which it is connected. It is identical to the WFQ
factor ’n’ in "Programming of the Peak Rate Limiter / PCR
Shaper" on page 4-58. 1/n = W is the weight factor. The value
WFQ factor = 0 connects the queue directly to the priority
multiplexor bypassing the WFQ Multiplexer (see Figure 3-3). (If
more then one queue is connected to the priority multiplexer, then
scheduled queues are served with LIFO bahavior).
