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
        ...
