RX FIFO Low
Watermark Port 5
Low watermark for RX FIFO port 5. The default
value is 1840 bytes. When the port is in flow
control and the amount of data stored in the FIFO
goes below this value, the flow control command
is terminated in the corresponding TX MAC.

RX FIFO Low
Watermark Port 6
Low watermark for RX FIFO port 6. The default
value is 1840 bytes. When the port is in flow
control and the amount of data stored in the FIFO
goes below this value, the flow control command
is terminated in the corresponding TX MAC.

RX FIFO Low
Watermark Port 7
Low watermark for RX FIFO port 7. The default
value is 1840 bytes.When the port is in flow
control and the amount of data stored in the FIFO
goes below this value, the flow control command
is terminated in the corresponding TX MAC.

RX FIFO Low
Watermark Port 8
Low watermark for RX FIFO port 8. The default
value is 1840 bytes. When the port is in flow
control and the amount of data stored in the FIFO
goes below this value, the flow control command
is terminated in the corresponding TX MAC.

RX FIFO Low
Watermark Port 9
Low watermark for RX FIFO port 9. The default
value is 1840 bytes. When the port is in flow
control and the amount of data stored in the FIFO
goes below this value, the flow control command
is terminated in the corresponding TX MAC.
