Kel's basically right here. Nevertheless, guessnet allows for a more unified
way of choosing the right logical interface for several physical interfaces.
For example, if a guessnet peer test (probing for IP/MAC addresses) is
appropriate it doesn't matter if your using a wired or a wireless device.
Since you can't use guessnet in combination with the wpa-roam solution you
have to implement one mapping rule in wpa_supplicant.conf via id_str options
and one for other devices in /e/n/i via the guessnet mechanism.
Fortunately, "test ..." lines (necessary for guessnet) in a logical interface
block don't disturb wpa-roam, so you can at least use one and the same
logical interface with guessnet and wpa-roam managed devices.

You can work around this by specifying the BSSID in wpa_supplicant.conf.
Kind regards,
