[Notification Type] RequestTimerCall [Description] 
Indicates that the miniport driver requires the operating system-specific port driver to call the miniport driver’s HwScsiTimer routine in the requested number of microseconds. If this value is set, ScsiPortNotification requires two additional parameters: (1) the entry point for the miniport driver’s HwScsiTimer routine, and (2) a MiniportTimerValue interval, in microseconds. Note that the resolution of the system timer is approximately 10 milliseconds.
