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. | |
