76 * struct cfg80211_ops - backend description for wireless configuration
78 * This struct is registered by fullmac card drivers and/or wireless stacks
79 * in order to handle configuration requests on their interfaces.
81 * All callbacks except where otherwise noted should return 0
82 * on success or a negative error code.
84 * All operations are currently invoked under rtnl for consistency with the
85 * wireless extensions but this is subject to reevaluation as soon as this
86 * code is used more widely and we have a first user without wext.
88 * @add_virtual_intf: create a new virtual interface with the given name
90 * @del_virtual_intf: remove the virtual interface determined by ifindex.
92 * @change_virtual_intf: change type of virtual interface
94 * @add_key: add a key with the given parameters. @mac_addr will be %NULL
95 * when adding a group key.
97 * @get_key: get information about the key with the given parameters.
98 * @mac_addr will be %NULL when requesting information for a group
99 * key. All pointers given to the @callback function need not be valid
102 * @del_key: remove a key given the @mac_addr (%NULL for a group key)
105 * @set_default_key: set the default key on an interface
