Data link layer active reporting


Turn On this parameter for a Root Port, if the attached Endpoint supports the optional capability of reporting the DL_Active state of the Data Link Control and Management State Machine. For a hot-plug capable Endpoint (as indicated by the Hot Plug Capable field of the Slot Capabilities register), this parameter must be turned On. For Root Port components that do not support this optional capability, turn Off this option.

Surprise down reporting On/Off When your turn this option On, an Endpoint supports the optional capability of detecting and reporting the surprise down error condition. The error condition is read from the Root Port.
