Hi Pavel The phydev name is not particularly nice: !mdio-mux!mdio@1!switch@0!mdio:00 !mdio-mux!mdio@1!switch@0!mdio:01 !mdio-mux!mdio@1!switch@0!mdio:02 !mdio-mux!mdio@2!switch@0!mdio:00 !mdio-mux!mdio@2!switch@0!mdio:01 !mdio-mux!mdio@2!switch@0!mdio:02 !mdio-mux!mdio@4!switch@0!mdio:00 !mdio-mux!mdio@4!switch@0!mdio:01 !mdio-mux!mdio@4!switch@0!mdio:02 400d0000.ethernet-1:00 400d0000.ethernet-1:01 fixed-0:00 The interface name are: 1: lo: 2: eth0: 3: eth1: 4: lan0@eth1: 5: lan1@eth1: 6: lan2@eth1: 7: lan3@eth1: 8: lan4@eth1: 9: lan5@eth1: 10: lan6@eth1: 11: lan7@eth1: 12: lan8@eth1: 13: optical3@eth1: 14: optical4@eth1: You could make a good guess at matching to two together, but it is error prone. Phys are low level things which the user is not really involved in. They interact with interface names. ethtool, ip, etc, all use interface names. In fact, i don't know of any tool which uses phydev names. Andrew
