Port 0 Current Transmit Flow Control Enable (CUR_TX_FC_MII)
This bit indicates the actual transmit flow setting of switch Port 0.
0: Flow control transmit is currently disabled
1: Flow control transmit is currently enabled
Port 0 Receive Flow Control Enable (RX_FC_MII)
When the MANUAL_FC_MII bit is set, or Virtual Auto-Negotiation is
disabled, this bit enables/disables the detection of full-duplex Pause packets
on switch Port 0.
0: Disable flow control receive
1: Enable flow control receive
Port 0 Transmit Flow Control Enable (TX_FC_MII)
When the MANUAL_FC_MII bit is set, or Virtual Auto-Negotiation is
