UNREGISTER_NETDEVICE(9) 				      Network device support					   UNREGISTER_NETDEVICE(9)

NAME
       unregister_netdevice_notifier - unregister a network notifier block

SYNOPSIS
       int unregister_netdevice_notifier(struct notifier_block * nb);

ARGUMENTS
       nb
	   notifier

DESCRIPTION
       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.
