unregister_netdevice_notifier — unregister a network notifier block
int unregister_netdevice_notifier (
struct notifier_block * nb)
;
Unregister a notifier previously registered by
register_netdevice_notifier
. The notifier is unlinked into the
kernel structures and may then be reused. A negative errno code
is returned on a failure.
After unregistering unregister and down device events are synthesized for all devices on the device list to the removed notifier to remove the need for special case cleanup code.
