CompletionRoutine(
  IN  PDEVICE_OBJECT DeviceObject,
  IN  PIRP Irp,
  IN  PVOID Context
  );

Routine Description:

    This routine does not complete the Irp. It is used to signal to a
    synchronous part of the NBT driver that it can proceed (i.e.
    to allow some code that is waiting on a "KeWaitForSingleObject" to
    proceeed.

Arguments:

    DeviceObject - unused.

    Irp - Supplies Irp that the transport has finished processing.

    Context - Supplies the event associated with the Irp.

Return Value:

    The STATUS_MORE_PROCESSING_REQUIRED so that the IO system stops
    processing Irp stack locations at this point.
