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,
