This along with the previous register determines how
many “64 byte blocks” of packet data are allowed on an
input port in a preset period. The period is 50ms for
100BT or 500ms for 10BT. The default is 1%.

Description
1, enable full-duplex flow control on switch MII/RMII
interface.
0, disable full-duplex flow control on switch MII/RMII
interface.
1, the switch SW4-MII/RMII is in 10Mbps mode.
0, the switch SW4-MII/RMII is in 100Mbps mode
1, will replace null VID with port VID (12 bits).
0, no replacement for null VID.
