Additionally, the patch improves the check itself: To check if the currently installed OVS supports the ARP responder feature, we try to add a flow that references an OpenFlow ARP extension via ofctl. The test may fail due to an (expected) Runtime error, or due to some other unexpected error. In such a case the error was previously masked and tossed away. * Clean up ARP responder unit test * Extract ARP responder flow actions to be used by the unit tests, functional test as well as the ARP responder code itself After this patch, if the sanity check returned False but the user never ran it or ignored its results, the OVS agent will output errors to the log every time an ARP entry is (attempted) to be added or removed from the flow table.
