+ * DESCRIPTION: This function is called to get the IRQ routing table for a
+ *              specific bus.  The caller must first acquire a handle for the
+ *              desired bus.  The routine table is placed in the buffer pointed

+ *
+ *              If the function fails an appropriate status will be returned
+ *              and the value of Out_buffer is undefined.
+ *
+ *              This function attempts to execute the _PRT method contained in
+ *              the object indicated by the passed Device_handle.
