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.

3744 * pre-authentication. If wpa_supplicant is performing scan request
3745 * (ap_scan=1), this event is optional since scan results can be used
3746 * to add pre-authentication candidates. union

3753 * on the candidate list. In addition, it can be called for the current
3754 * AP and APs that have existing PMKSA cache entries. wpa_supplicant
3755 * will automatically skip pre-authentication in cases where a valid
3756 * PMKSA exists. When more than one candidate exists, this event should

3886 * these events only after successfully completed probe_req_report()

3888 * in station mode. In AP mode, Probe Request frames should always be
3894 * EVENT_NEW_STA - New wired device noticed
3896 * This event is used to indicate that a new device has been detected
3897 * in a network that does not use association-like functionality (i.e.,
3898 * mainly wired Ethernet). This can be used to start EAPOL
3899 * authenticator when receiving a frame from a device. The address of

3944 EVENT_CHANNEL_LIST_CHANGED
,
3947 * EVENT_INTERFACE_UNAVAILABLE - Notify that interface is unavailable
3949 * This event is used to indicate that the driver cannot maintain this
3950 * interface in its operation mode anymore. The most likely use for
3951 * this is to indicate that AP mode operation is not available due to
3952 * operating channel would need to be changed to a DFS channel when
3953 * the driver does not support radar detection and another virtual
3954 * interfaces caused the operating channel to change. Other similar

,
3962 * EVENT_BEST_CHANNEL
3964 * Driver generates this event whenever it detects a better channel
