TxQueThr
Transmit Queue Threshold
These bits determine the threshold of the Transmit
Queue. When the Transmit queue exceeds this limit, a
packet that destined to this queue will be discarded.
000: Threshold is 64 in 1M, 256 in 4M
001: Threshold is 128 in 1M, 512 in 4M
010: Threshold is 192 in 1M, 768 in 4M
011: Threshold is 256 in 1M, 1024 in 4M
100: Threshold is 320 in 1M, 1280 in 4M
101: Threshold is 384 in 1M, 1536 in 4M
110: Threshold is 448 in 1M, 1792 in 4M
111: Threshold is 512 in 1M, 2048 in 4M

5
AddrRecF
Address Recognition Failed.
This bit is set by the GT-482xx when the address recog-
nition cycle fails (due to a large number of MAC
addresses).
0x0
6
FlushTxQ
Flush Tx Queue.
This bit is set by the GT-482xx when one of the Tx
queues is flushed due to the Watchdog Timer.
0x0
7
LinkChange
Link State Change.
This bit is set by the GT-482xx upon a change in the link
state (down->up, up->down) for any port.
0x0
8
Part
Partition.
This bit is set by the GT-482xx upon entering Partition
state in one of the ports.
