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. 15 */ 16 17#ifndef DRIVER_H 18#define DRIVER_H 19 20#define WPA_SUPPLICANT_DRIVER_VERSION 4 21 22#include "common/defs.h" 23#include "utils/list.h" 24 25#define HOSTAPD_CHAN_DISABLED 0x00000001 26#define HOSTAPD_CHAN_PASSIVE_SCAN 0x00000002 27#define HOSTAPD_CHAN_NO_IBSS 0x00000004 28#define HOSTAPD_CHAN_RADAR 0x00000008 29#define HOSTAPD_CHAN_HT40PLUS 0x00000010 30#define HOSTAPD_CHAN_HT40MINUS 0x00000020 31#define HOSTAPD_CHAN_HT40 0x00000040 32#define HOSTAPD_CHAN_SURVEY_LIST_INITIALIZED 0x00000080 33 34#define HOSTAPD_CHAN_DFS_UNKNOWN 0x00000000 35#define HOSTAPD_CHAN_DFS_USABLE 0x00000100 36#define HOSTAPD_CHAN_DFS_UNAVAILABLE 0x00000200 37#define HOSTAPD_CHAN_DFS_AVAILABLE 0x00000300 38#define HOSTAPD_CHAN_DFS_MASK 0x00000300 39 40#define HOSTAPD_CHAN_VHT_10_70 0x00000800 41#define HOSTAPD_CHAN_VHT_30_50 0x00001000 42#define HOSTAPD_CHAN_VHT_50_30 0x00002000 43#define HOSTAPD_CHAN_VHT_70_10 0x00004000 44 45enum reg_change_initiator { 46 REGDOM_SET_BY_CORE, 47 REGDOM_SET_BY_USER, 48 REGDOM_SET_BY_DRIVER, 49 REGDOM_SET_BY_COUNTRY_IE, 50 REGDOM_BEACON_HINT, 51};
