It makes this address instable, variable during bridge life-cycle, which is not good for DHCP. For example, I want to attach multiple virtual devices to one physical. Then, I need to make sure that after each virtual device addition, bridge addr is not changed and still addr of the physical device. Why not to use MAC of the first attached device? -- Thanks, Dmitry.
