Alioune, If you use networking-sfc master code , you can use create flow-classifier without logical-source-port specified . But if back-end driver is OVS , you will end up failure in ovs_driver checks . If i remembered correct , logical_source_port restriction is to avoid retrun packets to get reclassified .
