Hi Johannes,

I received a couple of reports from people who got problem with brcmfmac 
when a scheduled scan is requested, without any ssid specified. 
Currently, brcmfmac basically rejects the request. So what are valid 
usage scenarios for scheduled scans with respect to the n_ssid, 
n_channels, and n_matchsets. In the kernel doc below it says a 
zero-length ssid means 'no match'. I suppose it means any ssid which 
signal is above RRSI threshold will match.

Regards,
Arend
