Switch Looopback MII
When set, transmissions from the switch fabric Port 0(Host MAC) are not
sent to the Host MAC. Instead, they are looped back into the switch engine.
From the MAC viewpoint, this is effectively a FAR LOOPBACK.
If loopback is enabled during half-duplex operation, then the Enable Receive
Own Transmit bit in the

This mode works even if the Isolate bit of the

Switch Collision Test MII
When set, the collision signal to the switch fabric Port 0(Host MAC) is active
during transmission from the switch engine.
It is recommended that this bit be used only when using loopback mode.

Current Speed/Duplex Indication
This field indicates the current speed and duplex of the Virtual PHY link.

SQEOFF
This bit enables/disables the Signal Quality Error (Heartbeat) test.
