The message means that if the found route were to be installed, the flow would be sent out the same port that it came in on at either the source or destination access point switch. NOX state-wise, it means we have a link connected to the same port as a switch, which is incorrect. In the test code, the inport/outport fields of the FullRoute object describe where the endhosts are connected, not where the links are connected (which is on port 0).
