Yes, this is how it works. You call AddNetwork and in response you
will get a unique D-Bus Object Path that represents the network. The
Object Path is what you pass to the SelectNetwork and that allows you
to uniquely specify the network even if they have the same SSID.
If you do not select a specific network, the supplicant will auto-
select one for you. It should respect the "priority" property. But if
it's not, getting the "-dddt" output from the supplicant would be
useful.
