Enable Receive Own Transmit
When set, the switch port will receive its own transmission if it is looped back
from the PHY. Normally, this function is only used in Half Duplex PHY
loopback.

Reject MAC Types
When set, MAC control frames (packets with a type field of 8808h) are
filtered. When cleared, MAC Control frames, other than MAC Control Pause
frames, are sent to the forwarding process. MAC Control Pause frames are
always consumed by the switch.
RX Enable
When set, the receive port is enabled. When cleared, the receive port is
disabled.
Port x MAC Receive Configuration Register (MAC_RX_CFG_x)
This read/write register configures the packet type passing parameters of the port.
