* on success or a negative error code.
*
* 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.
*
* @change_virtual_intf: change type of virtual interface
*
* @add_key: add a key with the given parameters. @mac_addr will be %NULL
* when adding a group key.
*
* @get_key: get information about the key with the given parameters.
* @mac_addr will be %NULL when requesting information for a group
* key. All pointers given to the @callback function need not be valid
* after it returns.
*
* @del_key: remove a key given the @mac_addr (%NULL for a group key)
* and @key_index
*
* @set_default_key: set the default key on an interface
*
* @add_beacon: Add a beacon with given parameters, @head, @interval
* and @dtim_period will be valid, @tail is optional.
* @set_beacon: Change the beacon parameters for an access point mode
* interface. This should reject the call when no beacon has been
* configured.
* @del_beacon: Remove beacon configuration and stop sending the beacon.
*
* @add_station: Add a new station.
*
* @del_station: Remove a station; @mac may be NULL to remove all stations.
*
* @change_station: Modify a given station.
