This bit in combination with Register16/32/48/64/80
bit 0 will select the split of 1/2/4 queues:
{Register177 bit 1, Register16 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
0 = disable tag drop
1 = enable tag drop
0, strict priority, will transmit all the packets from
this priority queue 3 before transmit lower priority
queue.
1, bit[6:0] reflect the packet number allow to
transmit from this priority queue 3 within a certain
time
Packet number for Transmit Queue 3 for highest
priority packets in four queues mode
