    base-files: set MAC for bridge ports (devices) instead of bridge itself
    
    This restores the original config_generate behaviour. With MAC set for
    bridged devices the bridge automatically gets its MAC adjusted (it picks
    the lowest MAC of bridged devices).
    
    This fixes confusing interfaces setup (bridge ports not having custom
    MAC assigned).
