After I replied last night I was thinking perhaps the Pi doesn't
advertise the feature... and indeed this is true. I removed the check
and scanning worked just fine on the RPi3. So brcmfmac is just lazy and
never bothered to include this feature.

I guess, once again, we need to tailor our code to handle this driver,
ugh.

I'll send v2 soon.
