14 * This file defines a driver interface used by both %wpa_supplicant and
15 * hostapd. The first part of the file defines data structures used in various
16 * driver operations. This is followed by the struct wpa_driver_ops that each
17 * driver wrapper will beed to define with callback functions for requesting
18 * driver operations. After this, there are definitions for driver event
19 * reporting with wpa_supplicant_event() and some convenience helper functions
20 * that can be used to report events.

436 * target AP is advertising support for FT and is using the same MDIE
437 * and SSID as the current AP.
439 * The driver is responsible for reporting the FT IEs received from the
440 * AP's response using wpa_supplicant_event() with EVENT_FT_RESPONSE

2573 * pre-authentication. If wpa_supplicant is performing scan request
2574 * (ap_scan=1), this event is optional since scan results can be used

2597 * up secure direct link connection between two stations as defined in
2598 * IEEE 802.11e with a new PeerKey mechanism that replaced the original
2599 * STAKey negotiation. The caller will need to set peer address for the
2605 * EVENT_TDLS - Request TDLS operation
2607 * This event can be used to request a TDLS operation to be performed.
2612 * EVENT_FT_RESPONSE - Report FT (IEEE 802.11r) response IEs
2614 * The driver is expected to report the received FT IEs from
2615 * FT authentication sequence from the AP. The FT IEs are included in
2616 * the extra information in union wpa_event_data::ft_ies.
2621 * EVENT_IBSS_RSN_START - Request RSN authentication in IBSS
2623 * The driver can use this event to inform wpa_supplicant about a STA

2801 * This event is used to indicate that the driver cannot maintain this
2802 * interface in its operation mode anymore. The most likely use for
2803 * this is to indicate that AP mode operation is not available due to
2804 * operating channel would need to be changed to a DFS channel when
2805 * the driver does not support radar detection and another virtual
2806 * interfaces caused the operating channel to change. Other similar
