Question on bssid mask with ath10k

["Jose Núñez-Martínez (CTTC)"]

Hi,
the reason for starting a virtual device in monitor mode is to infuence 
Rx filters in firmware as pointed out in [1]. The goal is to configure 
the wireless device in adhoc mode so that it can receive and send 
packets containing any mac destination address.

Thx,
Jose
