register_netdevice: register a network device

NAME

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.
