You need to be quite careful when using freq_list. wpa_supplicant will
use exactly what is provided there and if cfg80211 does not like what it
sees, it will reject this. Apparently duplicate entries would hit that
and so would channels that the driver does not support.
In general, it is much easier to just do "wpa_cli scan freq=4900-6000"
if you just want to scan all the enabled 5 GHz channels.
