Thanks for the fast reply.

Yes, I can for example not correctly run batman-adv over both wlan interfaces 
and one/both of the ethernet interfaces. At least not without making sure that 
I manually change one of the devices mac addresses.

batman-adv will not be able to correctly distinguish the ethernet and WLAN 
link because they look like coming from the same interface (even when they are 
actually from complete different types of interfaces).

There are most likely similar problems with other protocols on top of 
ethernet. Of course, it "works" when you always bridge most of the interfaces 
together and only require two different BSSIDs - what GL-iNet is doing in 
their firmware.

Kind regards,
