I discovered the same thing while experimenting with qemu and bridgeng.
I think it simply works different from (for example) widnows bridging.
I think it's meant to be like that.
It also looks more logical either. I think of the bridge as just a
packet router, which routes them to all the interfaces(physical and
virtual as well) so if the bridge intercepts them with it's own address
they can't ereach other interfaces, obviosusly.
Maybe I'm wrong here?
No, you are absolutely right! This is how bridging works.
It is not necessary for the birdge interface to have its own mac address,
since it will just forward the ethernet frame to all interfaces that are
part of the bridge device, with an exception for the interface that
received the frame.
Later, when the bridge learns the mac address location, it will just
forward the ethernet
frame to the correct interface. Therefore, if the frame destination is
the mac address of the bridge,
it will not forward it, since it simply already arrived at destination.
