Hi! Sorry, but I hadn't read this bugreport till today.
First of all I'd like to clarify that 4-address is not the only way to add a wifi interface to a bridge, I have done this for years with wifi interfaces on ap mode without using 4-address at all. So, setting 4-address on all wifi interfaces automatically doesn't seem good to me, so... what do you think if we add a new bridge_4addr option that lets you specify what interfaces should be configured with 4addr? Something like: bridge_4addr wlan0 wlan1 Does that sound ok? Regards. -- Manty/BestiaTester -> http://manty.net
