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_NO_IR 0x00000002 27#define HOSTAPD_CHAN_RADAR 0x00000008 28#define HOSTAPD_CHAN_HT40PLUS 0x00000010 29#define HOSTAPD_CHAN_HT40MINUS 0x00000020 30#define HOSTAPD_CHAN_HT40 0x00000040 31#define HOSTAPD_CHAN_SURVEY_LIST_INITIALIZED 0x00000080 32 33#define HOSTAPD_CHAN_DFS_UNKNOWN 0x00000000 34#define HOSTAPD_CHAN_DFS_USABLE 0x00000100 35#define HOSTAPD_CHAN_DFS_UNAVAILABLE 0x00000200 36#define HOSTAPD_CHAN_DFS_AVAILABLE 0x00000300 37#define HOSTAPD_CHAN_DFS_MASK 0x00000300 38 39#define HOSTAPD_CHAN_VHT_10_70 0x00000800 40#define HOSTAPD_CHAN_VHT_30_50 0x00001000 41#define HOSTAPD_CHAN_VHT_50_30 0x00002000 42#define HOSTAPD_CHAN_VHT_70_10 0x00004000 43 44#define HOSTAPD_CHAN_INDOOR_ONLY 0x00010000 45#define HOSTAPD_CHAN_GO_CONCURRENT 0x00020000 46 47/** 48 * enum reg_change_initiator - Regulatory change initiator 49 */ 50enum reg_change_initiator { 51 REGDOM_SET_BY_CORE, 52 REGDOM_SET_BY_USER, 53 REGDOM_SET_BY_DRIVER, 54 REGDOM_SET_BY_COUNTRY_IE, 55 REGDOM_BEACON_HINT, 56};
