For backward compatibility, cfg80211 also offers 36d70e9693SJohannes Berg * wireless extensions to userspace, but hides them from drivers completely. 37d70e9693SJohannes Berg * 38d70e9693SJohannes Berg * Additionally, cfg80211 contains code to help enforce regulatory spectrum 39d70e9693SJohannes Berg * use restrictions. 40d70e9693SJohannes Berg */ 41d70e9693SJohannes Berg 42d70e9693SJohannes Berg 43d70e9693SJohannes Berg /** 44d70e9693SJohannes Berg * DOC: Device registration 45d70e9693SJohannes Berg * 46d70e9693SJohannes Berg * In order for a driver to use cfg80211, it must register the hardware device 47d70e9693SJohannes Berg * with cfg80211. This happens through a number of hardware capability structs 48d70e9693SJohannes Berg * described below. 49d70e9693SJohannes Berg * 50d70e9693SJohannes Berg * The fundamental structure for each device is the 'wiphy', of which each 51d70e9693SJohannes Berg * instance describes a physical wireless device connected to the system. Each 52d70e9693SJohannes Berg * such wiphy can have zero, one, or many virtual interfaces associated with 53d70e9693SJohannes Berg * it, which need to be identified as such by pointing the network interface's 54d70e9693SJohannes Berg * @ieee80211_ptr pointer to a &struct wireless_dev which further describes 55d70e9693SJohannes Berg * the wireless part of the interface, normally this struct is embedded in the 56d70e9693SJohannes Berg * network interface's private data area. Drivers can optionally allow creating 57d70e9693SJohannes Berg * or destroying virtual interfaces on the fly, but without at least one or the 58d70e9693SJohannes Berg * ability to create some the wireless device isn't useful. 59d70e9693SJohannes Berg * 60d70e9693SJohannes Berg * Each wiphy structure contains device capability information, and also has 61d70e9693SJohannes Berg * a pointer to the various operations the driver offers. The definitions and 62d70e9693SJohannes Berg * structures here describe these capabilities in detail. 63d70e9693SJohannes Berg */ 64d70e9693SJohannes Berg 65704232c2SJohannes Berg /* 66d3236553SJohannes Berg * wireless hardware capability structures 67d3236553SJohannes Berg */ 68d3236553SJohannes Berg 69d3236553SJohannes Berg /** 70d3236553SJohannes Berg * enum ieee80211_band - supported frequency bands 71704232c2SJohannes Berg * 72d3236553SJohannes Berg * The bands are assigned this way because the supported 73d3236553SJohannes Berg * bitrates differ in these bands. 74d3236553SJohannes Berg * 75d3236553SJohannes Berg * @IEEE80211_BAND_2GHZ: 2.4GHz ISM band 76d3236553SJohannes Berg * @IEEE80211_BAND_5GHZ: around 5GHz band (4.9-5.7) 77abe37c4bSJohannes Berg * @IEEE80211_NUM_BANDS: number of defined bands 78d3236553SJohannes Berg */ 79d3236553SJohannes Berg enum ieee80211_band { 8013ae75b1SJouni Malinen IEEE80211_BAND_2GHZ = NL80211_BAND_2GHZ, 8113ae75b1SJouni Malinen IEEE80211_BAND_5GHZ = NL80211_BAND_5GHZ, 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.
