Priority 3 Transmit Percentage - This percentage value is sent from
FIFO priority 3 (maximum) when the p1_pri3_shape_en is set
(queue shaping enabled).
This is the percentage of the wire that packets from priority 3 receive
(which includes interpacket gap and preamble bytes).
If shaping is enabled on this queue then this value must be between
zero and 0d100 (not inclusive).
