The main problem here is that the scan results do not include the
correct SSID unless the client knows that it needs to probe for a
specific SSID.

As far as I can tell, wpa_supplicant supports this and no additional
changes would be needed for it. However, not all drivers support this
properly. There are two alternative ways of handing this:

- set ap_scan=2 in wpa_supplicant.conf and allow driver to take care of
  AP selection

- set ap_scan=1 and add scan_ssid=1 into a network block to request
  per-SSID scanning

Not all drivers support these (some support one, others the other, some
neither, and some both..). In other words, I would recommend trying both
and if neither works, I would report this to driver developers.
