Problem with the ROAM wpa_cli command and external scans.

[Ben Greear]

Previously (or so I believe), I could request a scan using 'iw', and then
tell wpa_cli to do a roam now than the scan is fresh.  I let user specify
the channels to scan with iw so that I can minimize scan time..which is a big help
when doing lots of virtual stations.

But, now it seems wpa_supplicant ignores these external scans.

Is there a better way to fix this other than to just hack wpa_supplicant
to have an override that allows it to use external scan results?
