 * Routine Description:
 *
 *    This routine is called at DIRQL by the system when the controller
 *    interrupts.
 *
 * Arguments:
 *
 *    Interrupt - a pointer to the interrupt object.
 *
 *    Context - a pointer to our controller data area for the controller
 *    that interrupted.   (This was set up by the call to
 *    IoConnectInterrupt).
 *
 * Return Value:
 *
 *    Normally returns TRUE, but will return FALSE if this interrupt was
 *    not expected.
 *
