Scan locks forever when connected to Wi-Fi

[bragma]

Hi,
I am testing this driver and found out a serious problem. It seems that scan is not working when connected to a network. Not much to report though, there are no logs on dmesg. Simply, the command:

iw dev wlp3s0 scan

Locks forever without results. Same happens scanning with wpa_cli:

scan
OK
<3>CTRL-EVENT-SCAN-STARTED
<3>CTRL-EVENT-SCAN-RESULTS

SCAN-RESULTS returns immediately and command "scan_results" shows only the initial scan values (those read by wpa_supplicant before connecting).

[bragma]

If i run iw with --debug option, it locks at the end of the log. Seems similar to a working run, but it never receives scan results.
