This needs to be unique to the switch I would say, ndo_get_phys_switch_id would return the physical number of the switch device in the tree/cluster, so that number plus the port name should be an unique differentiator that is good enough for e.g: a persistent naming rule? > > We can have multiple switches within one switch cluster. p->port will > be unique within one switch, but can be repeated in a cluster. > > We can also have multiple clusters, and again p->port will be re-used. -- Florian
