The "logical name" is a Consistent Name, and it is provided by biosdevname. Also see https://linux.dell.com/files/whitepapers/consistent_network_device_naming_in_linux.pdf . The 'p' is a pci bus, the 's' is a slot number. Since the interface does not move around once installed, the interface will always have the same name like 'enp4s0'. ifconfig will give you the names: $ ifconfig enp4s0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500 ... lo: flags=73<UP,LOOPBACK,RUNNING> mtu 65536 ... wlp3s0: flags=4099<UP,BROADCAST,MULTICAST> mtu 1500 ...
