|
* device is requested to go to a sleep state the port driver pauses any

|
* active streams and then calls the power notify callback to inform the
|
|
* miniport of the impending power down. The miniport then has an opportunity
|
|
* to save any necessary context before the adapter's PowerChangeState method
|
|
* is called. The process is reversed when the device is powering up. PortCls
|
|
* first calls the adapter's PowerChangeState method to power up the adapter.
|
|
* The port driver then calls the miniport's callback to allow the miniport to
|
|
* restore its context. Finally, the port driver unpauses any previously paused
