User Guidelines
When Short-Reach mode is enabled and is not forced, the VCT (Virtual Cable
Tester) length check must be performed. The VCT length check can be performed
only on a copper port operating at a speed of 1000 Mbps. If the media is not
copper or the link speed is not 1000 Mbps, Short-Reach mode is not applied.
When the interface is set to enhanced mode, after the VCT length check has
completed and set the power to low, an active monitoring for errors is done
continuously. In the case of errors crossing a certain threshold, the PHY will be
reverted to long reach.
Note that EEE cannot be enabled if the Short-Reach mode is enabled.
