I assigned different mac address for different vifs, I can only bring only one interface up. If I want to bring the second vif up, it always complains "SIOCSIFFLAGS: Device or resource busy". But I'm sure that STA vif can coexist with monitor mode vif. So I may need to add the code login to make the watchdog only work with the vif in STA mode. Then I can also store vif in the rtl8xxxu_priv structure if we presume it only works for station mode. Anyone can suggest whether if this assumption is correct or not? Chris
