For backward compatibility, cfg80211 also offers 32d70e9693SJohannes Berg * wireless extensions to userspace, but hides them from drivers completely. 33d70e9693SJohannes Berg * 34d70e9693SJohannes Berg * Additionally, cfg80211 contains code to help enforce regulatory spectrum 35d70e9693SJohannes Berg * use restrictions. 36d70e9693SJohannes Berg */ 37d70e9693SJohannes Berg 38d70e9693SJohannes Berg 39d70e9693SJohannes Berg /** 40d70e9693SJohannes Berg * DOC: Device registration 41d70e9693SJohannes Berg * 42d70e9693SJohannes Berg * In order for a driver to use cfg80211, it must register the hardware device 43d70e9693SJohannes Berg * with cfg80211. This happens through a number of hardware capability structs 44d70e9693SJohannes Berg * described below. 45d70e9693SJohannes Berg * 46d70e9693SJohannes Berg * The fundamental structure for each device is the 'wiphy', of which each 47d70e9693SJohannes Berg * instance describes a physical wireless device connected to the system. Each 48d70e9693SJohannes Berg * such wiphy can have zero, one, or many virtual interfaces associated with 49d70e9693SJohannes Berg * it, which need to be identified as such by pointing the network interface's 50d70e9693SJohannes Berg * @ieee80211_ptr pointer to a &struct wireless_dev which further describes 51d70e9693SJohannes Berg * the wireless part of the interface, normally this struct is embedded in the 52d70e9693SJohannes Berg * network interface's private data area. Drivers can optionally allow creating 53d70e9693SJohannes Berg * or destroying virtual interfaces on the fly, but without at least one or the 54d70e9693SJohannes Berg * ability to create some the wireless device isn't useful. 55d70e9693SJohannes Berg * 56d70e9693SJohannes Berg * Each wiphy structure contains device capability information, and also has 57d70e9693SJohannes Berg * a pointer to the various operations the driver offers. The definitions and 58d70e9693SJohannes Berg * structures here describe these capabilities in detail. 59d70e9693SJohannes Berg */ 60d70e9693SJohannes Berg 619f5e8f6eSJohannes Berg struct wiphy; 629f5e8f6eSJohannes Berg 63704232c2SJohannes Berg /* 64d3236553SJohannes Berg * wireless hardware capability structures 65d3236553SJohannes Berg */ 66d3236553SJohannes Berg 67d3236553SJohannes Berg /** 68d3236553SJohannes Berg * enum ieee80211_band - supported frequency bands 69704232c2SJohannes Berg * 70d3236553SJohannes Berg * The bands are assigned this way because the supported 71d3236553SJohannes Berg * bitrates differ in these bands. 72d3236553SJohannes Berg * 73d3236553SJohannes Berg * @IEEE80211_BAND_2GHZ: 2.4GHz ISM band 74d3236553SJohannes Berg * @IEEE80211_BAND_5GHZ: around 5GHz band (4.9-5.7) 753a0c52a6SVladimir Kondratiev * @IEEE80211_BAND_60GHZ: around 60 GHz band (58.32 - 64.80 GHz) 76abe37c4bSJohannes Berg * @IEEE80211_NUM_BANDS: number of defined bands 77d3236553SJohannes Berg */ 78d3236553SJohannes Berg enum ieee80211_band { 7913ae75b1SJouni Malinen IEEE80211_BAND_2GHZ = NL80211_BAND_2GHZ, 8013ae75b1SJouni Malinen IEEE80211_BAND_5GHZ = NL80211_BAND_5GHZ, 813a0c52a6SVladimir Kondratiev IEEE80211_BAND_60GHZ = NL80211_BAND_60GHZ, 82d3236553SJohannes Berg 83d3236553SJohannes Berg /* keep last */ 84d3236553SJohannes Berg IEEE80211_NUM_BANDS 85d3236553SJohannes Berg }; 86d3236553SJohannes Berg 87d3236553SJohannes Berg /** 88d3236553SJohannes Berg * enum ieee80211_channel_flags - channel flags 89d3236553SJohannes Berg * 90d3236553SJohannes Berg * Channel flags set by the regulatory control code. 91d3236553SJohannes Berg * 92d3236553SJohannes Berg * @IEEE80211_CHAN_DISABLED: This channel is disabled. 93d3236553SJohannes Berg * @IEEE80211_CHAN_PASSIVE_SCAN: Only passive scanning is permitted 94d3236553SJohannes Berg * on this channel. 95d3236553SJohannes Berg * @IEEE80211_CHAN_NO_IBSS: IBSS is not allowed on this channel. 96d3236553SJohannes Berg * @IEEE80211_CHAN_RADAR: Radar detection is required on this channel. 97689da1b3SLuis R.

To start a scan, the scan operation will 1109d70e9693SJohannes Berg * be invoked with a scan definition. This scan definition contains the 1110d70e9693SJohannes Berg * channels to scan, and the SSIDs to send probe requests for (including the 1111d70e9693SJohannes Berg * wildcard, if desired). A passive scan is indicated by having no SSIDs to 1112d70e9693SJohannes Berg * probe. Additionally, a scan request may contain extra information elements 1113d70e9693SJohannes Berg * that should be added to the probe request. The IEs are guaranteed to be 1114d70e9693SJohannes Berg * well-formed, and will not exceed the maximum length the driver advertised 1115d70e9693SJohannes Berg * in the wiphy structure. 1116d70e9693SJohannes Berg * 1117d70e9693SJohannes Berg * When scanning finds a BSS, cfg80211 needs to be notified of that, because 1118d70e9693SJohannes Berg * it is responsible for maintaining the BSS list; the driver should not 1119d70e9693SJohannes Berg * maintain a list itself. For this notification, various functions exist. 1120d70e9693SJohannes Berg * 1121d70e9693SJohannes Berg * Since drivers do not maintain a BSS list, there are also a number of 1122d70e9693SJohannes Berg * functions to search for a BSS and obtain information about it from the 1123d70e9693SJohannes Berg * BSS structure cfg80211 maintains. The BSS list is also made available 1124d70e9693SJohannes Berg * to userspace. 1125d70e9693SJohannes Berg */ 112672bdcf34SJouni Malinen 1127704232c2SJohannes Berg /** 11282a519311SJohannes Berg * struct cfg80211_ssid - SSID description 11292a519311SJohannes Berg * @ssid: the SSID 11302a519311SJohannes Berg * @ssid_len: length of the ssid 11312a519311SJohannes Berg */ 11322a519311SJohannes Berg struct cfg80211_ssid { 11332a519311SJohannes Berg u8 ssid[IEEE80211_MAX_SSID_LEN];
