R/W 0 Register 177 (0xB1): Port 1 Control 13 Register 193 (0xC1): Port 2 Control 13 Register 209 (0xD1): Port 3 Control 13 Register 225 (0xE1): Port 4 Control 13 Register 241 (0xF1): Port 5 Control 13 7 - 2 Reserved — RO 000000 1 4 Queue Split Enable This bit, in combination with Register16/32/48/64/ 80 Bit[0], will select the split of 1, 2, and 4 queues: {Register 177 Bit[1], Register 16 Bit[0] = }: 11 = Reserved. 10 = The port output queue is split into four priority queues or if map 802.1p to priority 0-3 mode. 01 = The port output queue is split into two priority queues or if map 802.1p to priority 0-3 mode. 00 = Single output queue on the port. There is no priority differentiation even though packets are classified into high and low priority. R/W 0 0 Enable Drop- ping Tag 0 = Disable tagged packets drop 1 = Enable tagged packets drop R/W 0 Register 178 (0xB2): Port 1 Control 14 Register 194 (0xC2): Port 2 Control 14 Register 210 (0xD2): Port 3 Control 14 Register 226 (0xE2): Port 4 Control 14 Register 242 (0xF2): Port 5 Control 14 7 Enable Port Transmit Queue 3 Ratio 0 = Strict priority, will transmit all the packets from this priority queue 3 before transmit lower priority queue. 1 = Bits[6:0] reflect the packet number allow to transmit from this priority queue 3 within a certain time. R/W 1 6 - 0 Port Trans- mit Queue 3 Ratio[6:0] Packet number for Transmit Queue 3 for highest priority packets in four queues mode.
