+		That is, the code below should call to shutter_shut()
+	III.NDIS calls to ipoib_restart() that calls to shutter_alive. Now, shutter_counter is again 0.
+	IV.	NDIS call to ipoib_pause() that sets the adapter to pause state, calls to shutter_shut. 
+		Now, the counter is again equals to -MAX_OPERATIONS
+	V.	NDIS calls to ipoib_restart that calls to shutter_alive. Shutter counter is 0 and we can start working
