I just realized it looks like we have two issues leap42 is the follow up on 13.x, but uses pre-13.x handling of ethX naming conventino - yast2-lan is still making a mess of network config when having to rename interfaces or finds interfaces with other names than expected. or actually, it does not even notice. would be practical to use the MAC addres to record / to make sure what is what for at least the physical interfaces ??
