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. | |
