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.

2294 * This optional event can be used to report changes in interface
2295 * status (interface added/removed) using union

2307 * for scan request (ap_scan=2 mode), this event is required for
2308 * pre-authentication. If wpa_supplicant is performing scan request
2309 * (ap_scan=1), this event is optional since scan results can be used
2310 * to add pre-authentication candidates. union
2311 * wpa_event_data::pmkid_candidate is used to report the BSSID of the
2312 * candidate and priority of the candidate, e.g., based on the signal
2313 * strength, in order to try to pre-authenticate first with candidates
2314 * that are most likely targets for re-association.

2317 * on the candidate list. In addition, it can be called for the current
2318 * AP and APs that have existing PMKSA cache entries. wpa_supplicant
2319 * will automatically skip pre-authentication in cases where a valid
2320 * PMKSA exists. When more than one candidate exists, this event should

2332 * up secure direct link connection between two stations as defined in
2333 * IEEE 802.11e with a new PeerKey mechanism that replaced the original
2334 * STAKey negotiation. The caller will need to set peer address for the

2466 * EVENT_RX_PROBE_REQ - Indicate received Probe Request frame
2468 * This event is used to indicate when a Probe Request frame has been
2469 * received. Information about the received frame is included in
2470 * union wpa_event_data::rx_probe_req. The driver is required to report
2471 * these events only after successfully completed probe_req_report()

2483 * mainly wired Ethernet). This can be used to start EAPOL
2484 * authenticator when receiving a frame from a device. The address of
2485 * the device is included in union wpa_event_data::new_sta.
2490 * EVENT_EAPOL_RX - Report received EAPOL frame
2492 * When in AP mode with hostapd, this event is required to be used to
2493 * deliver the receive EAPOL frames from the driver. With
2494 * %wpa_supplicant, this event is used only if the send_eapol() handler
2495 * is used to override the use of l2_packet for EAPOL frame TX.
2500 * EVENT_SIGNAL_CHANGE - Indicate change in signal strength
2502 * This event is used to indicate changes in the signal strength

2529 * results including an AP advertising a country code.
2531 EVENT_CHANNEL_LIST_CHANGED
,
2534 * EVENT_INTERFACE_UNAVAILABLE - Notify that interface is unavailable
2536 * This event is used to indicate that the driver cannot maintain this
2537 * interface in its operation mode anymore. The most likely use for
2538 * this is to indicate that AP mode operation is not available due to
2539 * operating channel would need to be changed to a DFS channel when
2540 * the driver does not support radar detection and another virtual
2541 * interfaces caused the operating channel to change. Other similar

2559 * This event should be called when a Deauthentication frame is dropped
