On Linux, wpa_supplicant will only request probe-scans when you have
"scan_ssid=1" in a network block.  Otherwise, it's up to the driver
whether passive or active scans are used.

You'll get a notification on the D-Bus interface when new scan results
are available, not sure about the socket interface.
