I did a quick hack bringing up the monitor interface using
ath10k_monitor_create and ath10k_monitor_scan but no luck the FW
crashed.

Also, monitor mode is not a good idea, cause what we need is beacon
frame generated by others.

The only way that I can get the IBSS beacon generated by another node
is by triggering the "iw wlan0 scan". But then, it makes no sense
since we need to that whenever a station join the IBSS.

So, is there any way to turn of the beacon filtering in IBSS mode for the FW?
