Bit Field Type Reset Description
22-16 PRI3_SEND_PERCENT R/W 0h 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).
14-8 PRI2_SEND_PERCENT R/W 0h Priority 2 Transmit Percentage - This percentage value is sent from
FIFO priority 2 (maximum) when the p1_pri2_shape_en is set
(queue shaping enabled).
This is the percentage of the wire that packets from priority 2 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).
6-0 PRI1_SEND_PERCENT R/W 0h Priority 1 Transmit Percentage - This percentage value is sent from
FIFO priority 1 (maximum) when the p1_pri1_shape_en is set
(queue shaping enabled).
This is the percentage of the wire that packets from priority 1 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).
