But in\nthis process, another receiver of this notification can veto the\nregistration. The netdev registration will be aborted because of this veto.\n\nThe register_netdevice() call will try to clean up the net_device using\nunregister_netdevice_queue() - which only uses the .priv_destructor to\nfree private resources. In this situation, .dellink will not be called.\n\nThe cleanup of the untagged batadv_meshif_vlan must thefore be done in the\ndestructor to avoid a leak of this object."
