DESCRIPTION

16       Unregister a notifier previously registered by
17       register_netdevice_notifier. The notifier is unlinked into the kernel
18       structures and may then be reused. A negative errno code is returned on
19       a failure.
20
21       After unregistering unregister and down device events are synthesized
22       for all devices on the device list to the removed notifier to remove
23       the need for special case cleanup code.
24
25       NOTE THAT this function must be used for notifiers that takes pointer
26       to 'struct net_device' as 3rd parameter.
