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.
