Bit [2]: Select Queue 2
Bit [3]: Select Queue 3
Note:
Strip priority applies between different selected queues (Q3>Q2>Q1>Q0)
Bit [4]: Enable flush Queue 0
Bit [5]: Enable flush Queue 1
Bit [6]: Enable flush Queue 2
Bit [7]: Enable flush Queue 3
When flush (drop frames) is enable, it starts when queue is too long or entry is too old. A queue is too long when it
reaches WRED thresholds. Queue 0 is not subject to early drop. Packets in queue 0 are dropped only when the
queue is too old. An entry is too old when it is older than the time programmed in the register TX_AGE [5:0]. CPU
can dynamically program this register reading register RQSS [7:4].
13.4.21 RQSS – Receive Queue Status
CPU Address:h324
Accessed by CPU, serial interface (RO)
CPU receive queue status
Bit [3:0]: Queue 3 to 0 not empty
Bit [4]: Head of line entry for Queue 0 is valid for too long. CPU Queue 0 has no WRED threshold.
Bit [7:5]: Head of line entry for Queue 3 to 1 is valid for too long or Queue length is longer than WRED
threshold.
13.4.22 TX_AGE – Tx Queue Aging timer
I2C Address: h07;CPU Address:h324
Accessed by CPU, serial interface (RW)
Bit [5:0]: Unit of 100ms
(Default 8)
Disable transmission queue aging if value is zero. Aging timer for all ports and queues.
This register must be set to 0 for ‘No Packet Loss Flow Control Test’.
