8850 *	register_netdev	- register a network device
8851 *	@dev: device to register
8852 *
8853 *	Take a completed network device structure and add it to the kernel
8854 *	interfaces. A %NETDEV_REGISTER message is sent to the netdev notifier
8855 *	chain. 0 is returned on success. A negative errno code is returned
8856 *	on a failure to set up the device, or if the name is a duplicate.
8857 *
8858 *	This is a wrapper around register_netdevice that takes the rtnl semaphore
8859 *	and expands the device name if you passed a format string to
8860 *	alloc_netdev.
