  142. * added to the end of the specified management frame is specified with
  143. * %NL80211_ATTR_IE. If the command succeeds, the requested data will be
  144. * added to all specified management frames generated by
  145. * kernel/firmware/driver.
  146. * Note: This command has been removed and it is only reserved at this
  147. * point to avoid re-using existing command number. The functionality this

  156. * NL80211_CMD_GET_SCAN and on the "scan" multicast group)
  157. * @NL80211_CMD_SCAN_ABORTED: scan was aborted, for unspecified reasons,
  158. * partial scan results may be available
  159. *
  160. * @NL80211_CMD_REG_CHANGE: indicates to userspace the regulatory domain
  161. * has been changed and provides details of the request information
  162. * that caused the change such as who initiated the regulatory request
  163. * (%NL80211_ATTR_REG_INITIATOR), the wiphy_idx
  164. * (%NL80211_ATTR_REG_ALPHA2) on which the request was made from if
  165. * the initiator was %NL80211_REGDOM_SET_BY_COUNTRY_IE or
  166. * %NL80211_REGDOM_SET_BY_DRIVER, the type of regulatory domain
  167. * set (%NL80211_ATTR_REG_TYPE), if the type of regulatory domain is
  168. * %NL80211_REG_TYPE_COUNTRY the alpha2 to which we have moved on
  169. * to (%NL80211_ATTR_REG_ALPHA2).
  170. * @NL80211_CMD_REG_BEACON_HINT: indicates to userspace that an AP beacon
  171. * has been found while world roaming thus enabling active scan or
  172. * any mode of operation that initiates TX (beacons) on a channel

  174. * if you are world roaming (regulatory domain set to world or if your
  175. * driver is using a custom world roaming regulatory domain) and while
  176. * doing a passive scan on the 5 GHz band you find an AP there (if not
  177. * on a DFS channel) you will now be able to actively scan for that AP
  178. * or use AP mode on your card on that same channel. Note that this will
  179. * never be used for channels 1-11 on the 2 GHz band as they are always
  180. * enabled world wide. This beacon hint is only sent if your device had
  181. * either disabled active scanning or beaconing on a channel. We send to
  182. * userspace the wiphy on which we removed a restriction from
  183. * (%NL80211_ATTR_WIPHY) and the channel on which this occurred
  184. * before (%NL80211_ATTR_FREQ_BEFORE) and after (%NL80211_ATTR_FREQ_AFTER)
  185. * the beacon hint was processed.
  186. *
  187. * @NL80211_CMD_AUTHENTICATE: authentication request and notification.
  188. * This command is used both as a command (request to authenticate) and
  189. * as an event on the "mlme" multicast group indicating completion of the
  190. * authentication process.
  191. * When used as a command, %NL80211_ATTR_IFINDEX is used to identify the
  192. * interface. %NL80211_ATTR_MAC is used to specify PeerSTAAddress (and
  193. * BSSID in case of station mode). %NL80211_ATTR_SSID is used to specify
  194. * the SSID (mainly for association, but is included in authentication
  195. * request, too, to help BSS selection. %NL80211_ATTR_WIPHY_FREQ is used
  196. * to specify the frequence of the channel in MHz. %NL80211_ATTR_AUTH_TYPE
  197. * is used to specify the authentication type. %NL80211_ATTR_IE is used to
  198. * define IEs (VendorSpecificInfo, but also including RSN IE and FT IEs)
  199. * to be added to the frame.
  200. * When used as an event, this reports reception of an Authentication
  201. * frame in station and IBSS modes when the local MLME processed the
  202. * frame, i.e., it was for the local STA and was received in correct
  203. * state. This is similar to MLME-AUTHENTICATE.confirm primitive in the
  204. * MLME SAP interface (kernel providing MLME, userspace SME). The
  205. * included %NL80211_ATTR_FRAME attribute contains the management frame
  206. * (including both the header and frame body, but not FCS). This event is
  207. * also used to indicate if the authentication attempt timed out. In that
  208. * case the %NL80211_ATTR_FRAME attribute is replaced with a
  209. * %NL80211_ATTR_TIMED_OUT flag (and %NL80211_ATTR_MAC to indicate which
  210. * pending authentication timed out).
  211. * @NL80211_CMD_ASSOCIATE: association request and notification; like
  212. * NL80211_CMD_AUTHENTICATE but for Association and Reassociation
  213. * (similar to MLME-ASSOCIATE.request, MLME-REASSOCIATE.request,
  214. * MLME-ASSOCIATE.confirm or MLME-REASSOCIATE.confirm primitives).
  215. * @NL80211_CMD_DEAUTHENTICATE: deauthentication request and notification; like
  216. * NL80211_CMD_AUTHENTICATE but for Deauthentication frames (similar to
  217. * MLME-DEAUTHENTICATION.request and MLME-DEAUTHENTICATE.indication
  218. * primitives).
  219. * @NL80211_CMD_DISASSOCIATE: disassociation request and notification; like
  220. * NL80211_CMD_AUTHENTICATE but for Disassociation frames (similar to
  221. * MLME-DISASSOCIATE.request and MLME-DISASSOCIATE.indication primitives).
  222. *
  223. * @NL80211_CMD_MICHAEL_MIC_FAILURE: notification of a locally detected Michael
  224. * MIC (part of TKIP) failure; sent on the "mlme" multicast group; the
  225. * event includes %NL80211_ATTR_MAC to describe the source MAC address of
  226. * the frame with invalid MIC, %NL80211_ATTR_KEY_TYPE to show the key
  227. * type, %NL80211_ATTR_KEY_IDX to indicate the key identifier, and
  228. * %NL80211_ATTR_KEY_SEQ to indicate the TSC value of the frame; this
  229. * event matches with MLME-MICHAELMICFAILURE.indication() primitive
  230. *
  231. * @NL80211_CMD_JOIN_IBSS: Join a new IBSS -- given at least an SSID and a
  232. * FREQ attribute (for the initial frequency if no peer can be found)
  233. * and optionally a MAC (as BSSID) and FREQ_FIXED attribute if those
  234. * should be fixed rather than automatically determined. Can only be
  235. * executed on a network interface that is UP, and fixed BSSID/FREQ
  236. * may be rejected. Another optional parameter is the beacon interval,
  237. * given in the %NL80211_ATTR_BEACON_INTERVAL attribute, which if not
  238. * given defaults to 100 TU (102.4ms).
  239. * @NL80211_CMD_LEAVE_IBSS: Leave the IBSS -- no special arguments, the IBSS is
  240. * determined by the network interface.
  241. *
  242. * @NL80211_CMD_MAX: highest used command number
  243. * @__NL80211_CMD_AFTER_LAST: internal use
