thx for your quick and very helpfull response. So if the driver handles Probe Request frame processing internally, what could possibly cause, that my mobile device is not being connected (being disconnected) to the wpa_supplicant (in AP mode)?

I have set a hotspot connection and the problem is that if i try to connect to it from any device i get this error from subject. I have also attached full log in here: https://pastebin.com/VyTgz0WA .
That NL80211_CMD_FRAME failure is reported for the case where
wpa_supplicant (in AP mode) is trying to send a Probe Response frame as
a response to the Probe Request frame that the driver delivered to upper
layers. However, the driver seems to refuse to transmit the response.
Taken into account that "closed driver" part, I'm not going to try to
speculate on this more than note that there are many drivers that handle
Probe Request frame processing internally and as such, I would not be
very surprised if they do not accept Probe Response frames from user
space. If the driver is indeed taking care of that functionality, I
would simply ignore this failure.
