This happens through a number of hardware capability structs 43d70e9693SJohannes Berg * described below. 44d70e9693SJohannes Berg * 45d70e9693SJohannes Berg * The fundamental structure for each device is the 'wiphy', of which each 46d70e9693SJohannes Berg * instance describes a physical wireless device connected to the system. Each 47d70e9693SJohannes Berg * such wiphy can have zero, one, or many virtual interfaces associated with 48d70e9693SJohannes Berg * it, which need to be identified as such by pointing the network interface's 49d70e9693SJohannes Berg * @ieee80211_ptr pointer to a &struct wireless_dev which further describes 50d70e9693SJohannes Berg * the wireless part of the interface, normally this struct is embedded in the 51d70e9693SJohannes Berg * network interface's private data area. Drivers can optionally allow creating 52d70e9693SJohannes Berg * or destroying virtual interfaces on the fly, but without at least one or the 53d70e9693SJohannes Berg * ability to create some the wireless device isn't useful. 54d70e9693SJohannes Berg * 55d70e9693SJohannes Berg * Each wiphy structure contains device capability information, and also has 56d70e9693SJohannes Berg * a pointer to the various operations the driver offers. The definitions and 57d70e9693SJohannes Berg * structures here describe these capabilities in detail. 58d70e9693SJohannes Berg */ 59d70e9693SJohannes Berg 60704232c2SJohannes Berg /* 61d3236553SJohannes Berg * wireless hardware capability structures 62d3236553SJohannes Berg */ 63d3236553SJohannes Berg 64d3236553SJohannes Berg /** 65d3236553SJohannes Berg * enum ieee80211_band - supported frequency bands 66704232c2SJohannes Berg * 67d3236553SJohannes Berg * The bands are assigned this way because the supported 68d3236553SJohannes Berg * bitrates differ in these bands. 69d3236553SJohannes Berg * 70d3236553SJohannes Berg * @IEEE80211_BAND_2GHZ: 2.4GHz ISM band 71d3236553SJohannes Berg * @IEEE80211_BAND_5GHZ: around 5GHz band (4.9-5.7) 72abe37c4bSJohannes Berg * @IEEE80211_NUM_BANDS: number of defined bands 73d3236553SJohannes Berg */ 74d3236553SJohannes Berg enum ieee80211_band { 7513ae75b1SJouni Malinen IEEE80211_BAND_2GHZ = NL80211_BAND_2GHZ, 7613ae75b1SJouni Malinen IEEE80211_BAND_5GHZ = NL80211_BAND_5GHZ, 77d3236553SJohannes Berg 78d3236553SJohannes Berg /* keep last */ 79d3236553SJohannes Berg IEEE80211_NUM_BANDS 80d3236553SJohannes Berg }; 81d3236553SJohannes Berg 82d3236553SJohannes Berg /** 83d3236553SJohannes Berg * enum ieee80211_channel_flags - channel flags 84d3236553SJohannes Berg * 85d3236553SJohannes Berg * Channel flags set by the regulatory control code. 86d3236553SJohannes Berg * 87d3236553SJohannes Berg * @IEEE80211_CHAN_DISABLED: This channel is disabled. 88d3236553SJohannes Berg * @IEEE80211_CHAN_PASSIVE_SCAN: Only passive scanning is permitted 89d3236553SJohannes Berg * on this channel. 90d3236553SJohannes Berg * @IEEE80211_CHAN_NO_IBSS: IBSS is not allowed on this channel. 91d3236553SJohannes Berg * @IEEE80211_CHAN_RADAR: Radar detection is required on this channel. 92689da1b3SLuis R.
