This is followed by the struct wpa_driver_ops that each 11145510Sdarrenr * driver wrapper will beed to define with callback functions for requesting 12317314Scy * driver operations. After this, there are definitions for driver event 13145510Sdarrenr * reporting with wpa_supplicant_event() and some convenience helper functions 14145510Sdarrenr * that can be used to report events. 15145510Sdarrenr */ 16145510Sdarrenr 17145510Sdarrenr#ifndef DRIVER_H 18145510Sdarrenr#define DRIVER_H 19145510Sdarrenr 20145510Sdarrenr#define WPA_SUPPLICANT_DRIVER_VERSION 4 21145510Sdarrenr 22145510Sdarrenr#include "common/defs.h" 23145510Sdarrenr#include "common/ieee802_11_defs.h" 24145510Sdarrenr#include "common/wpa_common.h" 25145510Sdarrenr#ifdef CONFIG_MACSEC 26145510Sdarrenr#include "pae/ieee802_1x_kay.h" 27145510Sdarrenr#endif /* CONFIG_MACSEC */ 28145510Sdarrenr#include "utils/list.h" 29145510Sdarrenr 30145510Sdarrenr#define HOSTAPD_CHAN_DISABLED 0x00000001 31145510Sdarrenr#define HOSTAPD_CHAN_NO_IR 0x00000002 32255332Scy#define HOSTAPD_CHAN_RADAR 0x00000008 33255332Scy#define HOSTAPD_CHAN_HT40PLUS 0x00000010 34255332Scy#define HOSTAPD_CHAN_HT40MINUS 0x00000020 35255332Scy#define HOSTAPD_CHAN_HT40 0x00000040 36255332Scy#define HOSTAPD_CHAN_SURVEY_LIST_INITIALIZED 0x00000080 37145510Sdarrenr 38255332Scy#define HOSTAPD_CHAN_DFS_UNKNOWN 0x00000000 39255332Scy#define HOSTAPD_CHAN_DFS_USABLE 0x00000100 40255332Scy#define HOSTAPD_CHAN_DFS_UNAVAILABLE 0x00000200 41255332Scy#define HOSTAPD_CHAN_DFS_AVAILABLE 0x00000300 42255332Scy#define HOSTAPD_CHAN_DFS_MASK 0x00000300 43145510Sdarrenr 44145510Sdarrenr#define HOSTAPD_CHAN_VHT_10_70 0x00000800 45255332Scy#define HOSTAPD_CHAN_VHT_30_50 0x00001000 46255332Scy#define HOSTAPD_CHAN_VHT_50_30 0x00002000 47255332Scy#define HOSTAPD_CHAN_VHT_70_10 0x00004000 48255332Scy 49255332Scy#define HOSTAPD_CHAN_INDOOR_ONLY 0x00010000 50255332Scy#define HOSTAPD_CHAN_GO_CONCURRENT 0x00020000 51255332Scy 52255332Scy#define HOSTAPD_CHAN_VHT_10_150 0x00100000 53145510Sdarrenr#define HOSTAPD_CHAN_VHT_30_130 0x00200000 54145510Sdarrenr#define HOSTAPD_CHAN_VHT_50_110 0x00400000 55145510Sdarrenr#define HOSTAPD_CHAN_VHT_70_90 0x00800000 56145510Sdarrenr#define HOSTAPD_CHAN_VHT_90_70 0x01000000 57145510Sdarrenr#define HOSTAPD_CHAN_VHT_110_50 0x02000000 58145510Sdarrenr#define HOSTAPD_CHAN_VHT_130_30 0x04000000 59145510Sdarrenr#define HOSTAPD_CHAN_VHT_150_10 0x08000000 60145510Sdarrenr 61145510Sdarrenr/* Allowed bandwidth mask */ 62145510Sdarrenrenum hostapd_chan_width_attr { 63145510Sdarrenr HOSTAPD_CHAN_WIDTH_10 = BIT(0), 64145510Sdarrenr HOSTAPD_CHAN_WIDTH_20 = BIT(1), 65145510Sdarrenr HOSTAPD_CHAN_WIDTH_40P = BIT(2), 66145510Sdarrenr HOSTAPD_CHAN_WIDTH_40M = BIT(3), 67255332Scy HOSTAPD_CHAN_WIDTH_80 = BIT(4), 68255332Scy HOSTAPD_CHAN_WIDTH_160 = BIT(5), 69145510Sdarrenr};
