I'm not sure I understand the reasoning here. Without a doubt kernel modules need to be built against the same configuration as the kernels that are loading them. So, conditional component of net_device should not cause crashes. FWIW, there are other conditionally compiled portions of net_device (NETPOLL, NET_POLL_CONTROLLER). I don't see the harm here.
