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