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

3585 * for scan request (ap_scan=2 mode), this event is required for
3586 * pre-authentication. If wpa_supplicant is performing scan request
3587 * (ap_scan=1), this event is optional since scan results can be used
3588 * to add pre-authentication candidates. union
3589 * wpa_event_data::pmkid_candidate is used to report the BSSID of the
3590 * candidate and priority of the candidate, e.g., based on the signal
3591 * strength, in order to try to pre-authenticate first with candidates
3592 * that are most likely targets for re-association.

3595 * on the candidate list. In addition, it can be called for the current
3596 * AP and APs that have existing PMKSA cache entries. wpa_supplicant
3597 * will automatically skip pre-authentication in cases where a valid
3598 * PMKSA exists. When more than one candidate exists, this event should

3610 * up secure direct link connection between two stations as defined in
3611 * IEEE 802.11e with a new PeerKey mechanism that replaced the original
3612 * STAKey negotiation. The caller will need to set peer address for the
3618 * EVENT_TDLS - Request TDLS operation
3620 * This event can be used to request a TDLS operation to be performed.
3625 * EVENT_FT_RESPONSE - Report FT (IEEE 802.11r) response IEs

3628 * FT authentication sequence from the AP. The FT IEs are included in
3629 * the extra information in union wpa_event_data::ft_ies.
3634 * EVENT_IBSS_RSN_START - Request RSN authentication in IBSS
3636 * The driver can use this event to inform wpa_supplicant about a STA
3637 * in an IBSS with which protected frames could be exchanged. This
3638 * event starts RSN authentication with the other STA to authenticate
3639 * the STA and set up encryption keys with it.

3725 * This event is used to indicate when a Probe Request frame has been
3726 * received. Information about the received frame is included in
3727 * union wpa_event_data::rx_probe_req. The driver is required to report
3728 * these events only after successfully completed probe_req_report()
3729 * commands to request the events (i.e., report parameter is non-zero)
3730 * in station mode. In AP mode, Probe Request frames should always be
3736 * EVENT_NEW_STA - New wired device noticed
3738 * This event is used to indicate that a new device has been detected
3739 * in a network that does not use association-like functionality (i.e.,
3740 * mainly wired Ethernet). This can be used to start EAPOL
3741 * authenticator when receiving a frame from a device. The address of
3742 * the device is included in union wpa_event_data::new_sta.
3747 * EVENT_EAPOL_RX - Report received EAPOL frame

3784 * results including an AP advertising a country code.
3786 EVENT_CHANNEL_LIST_CHANGED
,
3789 * EVENT_INTERFACE_UNAVAILABLE - Notify that interface is unavailable
3791 * This event is used to indicate that the driver cannot maintain this
3792 * interface in its operation mode anymore. The most likely use for
3793 * this is to indicate that AP mode operation is not available due to
3794 * operating channel would need to be changed to a DFS channel when
3795 * the driver does not support radar detection and another virtual
3796 * interfaces caused the operating channel to change. Other similar

3801 EVENT_INTERFACE_UNAVAILABLE
,
3804 * EVENT_BEST_CHANNEL
3806 * Driver generates this event whenever it detects a better channel
