Yes, I'll add SSID filtering soon, as separate patches, if that's okay.
For now, the SSIDs that you can pass via nl80211 are used in the
probe_reqs.

We can also filter on RSSI, SNR and/or group results into one event.
This are other features that our firmware supports.  For now I have not
exposed this, but it could also be added to nl80211 in the future.
