lapbeth_init_driver() ignores register_netdevice_notifier() errors and always returns success, which can leave the module loaded without its netdev notifier registered. Check the error and remove the packet type on failure. This is a future looking check, register_netdevice_notifier() only fails on double registration or if the registered notifier itself returns an error.
