It bridges * userspace and drivers, and offers some utility functionality associated * with 802.11. cfg80211 must, directly or indirectly via mac80211, be used * by all modern wireless drivers in Linux, so that they offer a consistent * API through nl80211. For backward compatibility, cfg80211 also offers * wireless extensions to userspace, but hides them from drivers completely. * * Additionally, cfg80211 contains code to help enforce regulatory spectrum * use restrictions. */ /** * DOC: Device registration * * In order for a driver to use cfg80211, it must register the hardware device * with cfg80211. This happens through a number of hardware capability structs * described below. * * The fundamental structure for each device is the 'wiphy', of which each * instance describes a physical wireless device connected to the system. Each * such wiphy can have zero, one, or many virtual interfaces associated with * it, which need to be identified as such by pointing the network interface's * @ieee80211_ptr pointer to a &struct wireless_dev which further describes * the wireless part of the interface, normally this struct is embedded in the * network interface's private data area. Drivers can optionally allow creating * or destroying virtual interfaces on the fly, but without at least one or the * ability to create some the wireless device isn't useful. * * Each wiphy structure contains device capability information, and also has * a pointer to the various operations the driver offers. The definitions and * structures here describe these capabilities in detail. */ struct wiphy; /* * wireless hardware capability structures */ /** * enum ieee80211_band - supported frequency bands * * The bands are assigned this way because the supported * bitrates differ in these bands. * * @IEEE80211_BAND_2GHZ: 2.4GHz ISM band * @IEEE80211_BAND_5GHZ: around 5GHz band (4.9-5.7) * @IEEE80211_BAND_60GHZ: around 60 GHz band (58.32 - 64.80 GHz) * @IEEE80211_NUM_BANDS: number of defined bands */ enum ieee80211_band { IEEE80211_BAND_2GHZ = NL80211_BAND_2GHZ, IEEE80211_BAND_5GHZ = NL80211_BAND_5GHZ, IEEE80211_BAND_60GHZ = NL80211_BAND_60GHZ, /* keep last */ IEEE80211_NUM_BANDS }; /** * enum ieee80211_channel_flags - channel flags * * Channel flags set by the regulatory control code. * * @IEEE80211_CHAN_DISABLED: This channel is disabled. * @IEEE80211_CHAN_PASSIVE_SCAN: Only passive scanning is permitted * on this channel. * @IEEE80211_CHAN_NO_IBSS: IBSS is not allowed on this channel. * @IEEE80211_CHAN_RADAR: Radar detection is required on this channel. * @IEEE80211_CHAN_NO_HT40PLUS: extension channel above this channel * is not permitted. * @IEEE80211_CHAN_NO_HT40MINUS: extension channel below this channel * is not permitted. * @IEEE80211_CHAN_NO_OFDM: OFDM is not allowed on this channel. * @IEEE80211_CHAN_NO_80MHZ: If the driver supports 80 MHz on the band, * this flag indicates that an 80 MHz channel cannot use this * channel as the control or any of the secondary channels. * This may be due to the driver or due to regulatory bandwidth * restrictions. * @IEEE80211_CHAN_NO_160MHZ: If the driver supports 160 MHz on the band, * this flag indicates that an 160 MHz channel cannot use this * channel as the control or any of the secondary channels. * This may be due to the driver or due to regulatory bandwidth * restrictions. */ enum ieee80211_channel_flags { IEEE80211_CHAN_DISABLED = 1<<0, IEEE80211_CHAN_PASSIVE_SCAN = 1<<1, IEEE80211_CHAN_NO_IBSS = 1<<2, IEEE80211_CHAN_RADAR = 1<<3, IEEE80211_CHAN_NO_HT40PLUS = 1<<4, IEEE80211_CHAN_NO_HT40MINUS = 1<<5, IEEE80211_CHAN_NO_OFDM = 1<<6, IEEE80211_CHAN_NO_80MHZ = 1<<7, IEEE80211_CHAN_NO_160MHZ = 1<<8, }; #define IEEE80211_CHAN_NO_HT40 \ (IEEE80211_CHAN_NO_HT40PLUS | IEEE80211_CHAN_NO_HT40MINUS) #define IEEE80211_DFS_MIN_CAC_TIME_MS 60000 #define IEEE80211_DFS_MIN_NOP_TIME_MS (30 * 60 * 1000) /** * struct ieee80211_channel - channel definition * * This structure describes a single channel for use * with cfg80211. * * @center_freq: center frequency in MHz * @hw_value: hardware-specific value for the channel * @flags: channel flags from &enum ieee80211_channel_flags. * @orig_flags: channel flags at registration time, used by regulatory * code to support devices with additional restrictions * @band: band this channel belongs to. * @max_antenna_gain: maximum antenna gain in dBi * @max_power: maximum transmission power (in dBm) * @max_reg_power: maximum regulatory transmission power (in dBm) * @beacon_found: helper to regulatory code to indicate when a beacon * has been found on this channel.

If there is already a list in driver * this new list replaces the existing one. Driver has to clear its ACL * when number of MAC addresses entries is passed as 0. Drivers which * advertise the support for MAC based ACL have to implement this callback. * * @start_radar_detection: Start radar detection in the driver. * * @update_ft_ies: Provide updated Fast BSS Transition information to the * driver. If the SME is in the driver/firmware, this information can be * used in building Authentication and Reassociation Request frames. * * @crit_proto_start: Indicates a critical protocol needs more link reliability * for a given duration (milliseconds).
