register_netdevice (9) Linux Manual Page
register_netdevice – register a network device
Synopsis
int register_netdevice(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.
Callers must hold the rtnl semaphore. You may want register_netdev instead of this.
BUGS: The locking appears insufficient to guarantee two parallel registers will not get the same name.
