The current version of the Host AP driver & wpa_supplicant uses a method
which moves AP selection to wpa_supplicant. This is not always the best
choice since wpa_supplicant does not have all the information available
for AP selection (it just picks the first one with suitable
configuration). The driver is supposed to provide the scan results in
prefered order, but the current version might not do this properly,
especially in cases where the APs use multiple SSIDs. Anyway, this is a
known issue and I'm working on a bit different alternative mechanism
that gives more control to the firmware/driver.
