Both "onboard" and "slot" are preferred over "path" because they're shorter and more descriptive (as long as the firmware provides correct values). The path, being based on PCI bus addressing, doesn't say much to most people -- at best, it's just a stable identifier. (For example, my server's integrated NIC port #1 is better named "eno1", not "enp3s0f0".) -- Mantas Mikulėnas
