REGISTER_NETDEV(9)					      Network device support						REGISTER_NETDEV(9)

NAME
       register_netdev - register a network device

SYNOPSIS
       int register_netdev(struct net_device * dev);

ARGUMENTS
       dev
	   device to register

DESCRIPTION
       Take a completed network device structure and add it to the kernel interfaces. A NETDEV_REGISTER message is sent to the netdev notifier
       chain. 0 is returned on success. A negative errno code is returned on a failure to set up the device, or if the name is a duplicate.

       This is a wrapper around register_netdevice that takes the rtnl semaphore and expands the device name if you passed a format string to
       alloc_netdev.
