Description
1 = Enable full duplex flow control on Switch MII interface.
0 = Disable full duplex flow control on Switch MII interface.
1 = The switch interface is in 10Mbps mode
0 = The switch interface is in 100Mbps mode
1 = Will replace NULL VID with port VID (12 bits)
0 = No replacement for NULL VID
This register along with the next register determines how many
“64 byte blocks” of packet data are allowed on an input port in a
preset period. The period is 67ms for 100BT or 500ms for
10BT. The default is 1%.
