It is a valid and correct assumption that one is able to put several devices at the same time on the same physical network and expect it to work. The behavior added by the change in question invalidates that. I'm trying to consider the long term aspects of this, which is that if more devices adopt this scheme we're in trouble if we blindly interpret the MAC address in this way. This firmware MAC property facility seems to be designed with only an extremely narrow use case being considered. -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
