 * All operations are currently invoked under rtnl for consistency with the
 * wireless extensions but this is subject to reevaluation as soon as this
 * code is used more widely and we have a first user without wext.

 * @add_virtual_intf: create a new virtual interface with the given name
 *
 * @del_virtual_intf: remove the virtual interface determined by ifindex.
