For backward compatibility, cfg80211 also offers 34d70e9693SJohannes Berg * wireless extensions to userspace, but hides them from drivers completely. 35d70e9693SJohannes Berg * 36d70e9693SJohannes Berg * Additionally, cfg80211 contains code to help enforce regulatory spectrum 37d70e9693SJohannes Berg * use restrictions. 38d70e9693SJohannes Berg */ 39d70e9693SJohannes Berg 40d70e9693SJohannes Berg 41d70e9693SJohannes Berg /** 42d70e9693SJohannes Berg * DOC: Device registration 43d70e9693SJohannes Berg * 44d70e9693SJohannes Berg * In order for a driver to use cfg80211, it must register the hardware device 45d70e9693SJohannes Berg * with cfg80211. This happens through a number of hardware capability structs 46d70e9693SJohannes Berg * described below. 47d70e9693SJohannes Berg * 48d70e9693SJohannes Berg * The fundamental structure for each device is the 'wiphy', of which each 49d70e9693SJohannes Berg * instance describes a physical wireless device connected to the system. Each 50d70e9693SJohannes Berg * such wiphy can have zero, one, or many virtual interfaces associated with 51d70e9693SJohannes Berg * it, which need to be identified as such by pointing the network interface's 52d70e9693SJohannes Berg * @ieee80211_ptr pointer to a &struct wireless_dev which further describes 53d70e9693SJohannes Berg * the wireless part of the interface, normally this struct is embedded in the 54d70e9693SJohannes Berg * network interface's private data area. Drivers can optionally allow creating 55d70e9693SJohannes Berg * or destroying virtual interfaces on the fly, but without at least one or the 56d70e9693SJohannes Berg * ability to create some the wireless device isn't useful. 57d70e9693SJohannes Berg * 58d70e9693SJohannes Berg * Each wiphy structure contains device capability information, and also has 59d70e9693SJohannes Berg * a pointer to the various operations the driver offers. The definitions and 60d70e9693SJohannes Berg * structures here describe these capabilities in detail. 61d70e9693SJohannes Berg */ 62d70e9693SJohannes Berg 639f5e8f6eSJohannes Berg struct wiphy; 649f5e8f6eSJohannes 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) 773a0c52a6SVladimir Kondratiev * @IEEE80211_BAND_60GHZ: around 60 GHz band (58.32 - 64.80 GHz) 78abe37c4bSJohannes Berg * @IEEE80211_NUM_BANDS: number of defined bands 79d3236553SJohannes Berg */ 80d3236553SJohannes Berg enum ieee80211_band { 8113ae75b1SJouni Malinen IEEE80211_BAND_2GHZ = NL80211_BAND_2GHZ, 8213ae75b1SJouni Malinen IEEE80211_BAND_5GHZ = NL80211_BAND_5GHZ, 833a0c52a6SVladimir Kondratiev IEEE80211_BAND_60GHZ = NL80211_BAND_60GHZ, 84d3236553SJohannes Berg 85d3236553SJohannes Berg /* keep last */ 86d3236553SJohannes Berg IEEE80211_NUM_BANDS 87d3236553SJohannes Berg }; 88d3236553SJohannes Berg 89d3236553SJohannes Berg /** 90d3236553SJohannes Berg * enum ieee80211_channel_flags - channel flags 91d3236553SJohannes Berg * 92d3236553SJohannes Berg * Channel flags set by the regulatory control code. 93d3236553SJohannes Berg * 94d3236553SJohannes Berg * @IEEE80211_CHAN_DISABLED: This channel is disabled. 958fe02e16SLuis R.
