Programmable Registers
29.9.31 ENET SWI Queue weights for each queue.
Defines the weight for the corresponding queue for all ports. A higher weight gives more
priority to the queue. Valid values are between 0 and 30 for each queue setting. Setting all
weights to 0 implements a strict priority scheme. Queue 3 is the highest priority queue.
