119  *
120  * @NL80211_CMD_GET_REG: ask the wireless core to send us its currently set
121  *      regulatory domain.
122  * @NL80211_CMD_SET_REG: Set current regulatory domain. CRDA sends this command
123  *      after being queried by the kernel. CRDA replies by sending a regulatory
124  *      domain structure which consists of %NL80211_ATTR_REG_ALPHA set to our
125  *      current alpha2 if it found a match. It also provides
126  *      NL80211_ATTR_REG_RULE_FLAGS, and a set of regulatory rules. Each
127  *      regulatory rule is a nested set of attributes  given by
128  *      %NL80211_ATTR_REG_RULE_FREQ_[START|END] and
129  *      %NL80211_ATTR_FREQ_RANGE_MAX_BW with an attached power rule given by
130  *      %NL80211_ATTR_REG_RULE_POWER_MAX_ANT_GAIN and
131  *      %NL80211_ATTR_REG_RULE_POWER_MAX_EIRP.
132  * @NL80211_CMD_REQ_SET_REG: ask the wireless core to set the regulatory domain
133  *      to the the specified ISO/IEC 3166-1 alpha2 country code. The core will
134  *      store this as a valid request and then query userspace for it.
135  *
136  * @NL80211_CMD_GET_MESH_PARAMS: Get mesh networking properties for the
137  *      interface identified by %NL80211_ATTR_IFINDEX
138  *
139  * @NL80211_CMD_SET_MESH_PARAMS: Set mesh networking properties for the
140  *      interface identified by %NL80211_ATTR_IFINDEX
141  *
142  * @NL80211_CMD_SET_MGMT_EXTRA_IE: Set extra IEs for management frames. The
143  *      interface is identified with %NL80211_ATTR_IFINDEX and the management
144  *      frame subtype with %NL80211_ATTR_MGMT_SUBTYPE. The extra IE data to be
145  *      added to the end of the specified management frame is specified with
146  *      %NL80211_ATTR_IE. If the command succeeds, the requested data will be
147  *      added to all specified management frames generated by
148  *      kernel/firmware/driver.
149  *      Note: This command has been removed and it is only reserved at this
150  *      point to avoid re-using existing command number. The functionality this
151  *      command was planned for has been provided with cleaner design with the
152  *      option to specify additional IEs in NL80211_CMD_TRIGGER_SCAN,
153  *      NL80211_CMD_AUTHENTICATE, NL80211_CMD_ASSOCIATE,
154  *      NL80211_CMD_DEAUTHENTICATE, and NL80211_CMD_DISASSOCIATE.
155  *
156  * @NL80211_CMD_GET_SCAN: get scan results
157  * @NL80211_CMD_TRIGGER_SCAN: trigger a new scan with the given parameters
158  * @NL80211_CMD_NEW_SCAN_RESULTS: scan notification (as a reply to
159  *      NL80211_CMD_GET_SCAN and on the "scan" multicast group)
160  * @NL80211_CMD_SCAN_ABORTED: scan was aborted, for unspecified reasons,
161  *      partial scan results may be available
162  *
163  * @NL80211_CMD_REG_CHANGE: indicates to userspace the regulatory domain
164  *      has been changed and provides details of the request information
165  *      that caused the change such as who initiated the regulatory request
166  *      (%NL80211_ATTR_REG_INITIATOR), the wiphy_idx
167  *      (%NL80211_ATTR_REG_ALPHA2) on which the request was made from if
168  *      the initiator was %NL80211_REGDOM_SET_BY_COUNTRY_IE or
169  *      %NL80211_REGDOM_SET_BY_DRIVER, the type of regulatory domain
170  *      set (%NL80211_ATTR_REG_TYPE), if the type of regulatory domain is
171  *      %NL80211_REG_TYPE_COUNTRY the alpha2 to which we have moved on
172  *      to (%NL80211_ATTR_REG_ALPHA2).
173  * @NL80211_CMD_REG_BEACON_HINT: indicates to userspace that an AP beacon
174  *      has been found while world roaming thus enabling active scan or
175  *      any mode of operation that initiates TX (beacons) on a channel
176  *      where we would not have been able to do either before. As an example
177  *      if you are world roaming (regulatory domain set to world or if your
178  *      driver is using a custom world roaming regulatory domain) and while
179  *      doing a passive scan on the 5 GHz band you find an AP there (if not
180  *      on a DFS channel) you will now be able to actively scan for that AP
181  *      or use AP mode on your card on that same channel. Note that this will
182  *      never be used for channels 1-11 on the 2 GHz band as they are always
183  *      enabled world wide. This beacon hint is only sent if your device had
184  *      either disabled active scanning or beaconing on a channel. We send to
185  *      userspace the wiphy on which we removed a restriction from
186  *      (%NL80211_ATTR_WIPHY) and the channel on which this occurred
187  *      before (%NL80211_ATTR_FREQ_BEFORE) and after (%NL80211_ATTR_FREQ_AFTER)
188  *      the beacon hint was processed.
189  *
190  * @NL80211_CMD_AUTHENTICATE: authentication request and notification.
191  *      This command is used both as a command (request to authenticate) and
192  *      as an event on the "mlme" multicast group indicating completion of the
193  *      authentication process.
194  *      When used as a command, %NL80211_ATTR_IFINDEX is used to identify the
195  *      interface. %NL80211_ATTR_MAC is used to specify PeerSTAAddress (and
196  *      BSSID in case of station mode). %NL80211_ATTR_SSID is used to specify
197  *      the SSID (mainly for association, but is included in authentication
198  *      request, too, to help BSS selection. %NL80211_ATTR_WIPHY_FREQ is used
199  *      to specify the frequence of the channel in MHz. %NL80211_ATTR_AUTH_TYPE
200  *      is used to specify the authentication type. %NL80211_ATTR_IE is used to
201  *      define IEs (VendorSpecificInfo, but also including RSN IE and FT IEs)
202  *      to be added to the frame.
203  *      When used as an event, this reports reception of an Authentication
204  *      frame in station and IBSS modes when the local MLME processed the
205  *      frame, i.e., it was for the local STA and was received in correct
206  *      state. This is similar to MLME-AUTHENTICATE.confirm primitive in the
207  *      MLME SAP interface (kernel providing MLME, userspace SME). The
208  *      included %NL80211_ATTR_FRAME attribute contains the management frame
209  *      (including both the header and frame body, but not FCS). This event is
210  *      also used to indicate if the authentication attempt timed out. In that
211  *      case the %NL80211_ATTR_FRAME attribute is replaced with a
212  *      %NL80211_ATTR_TIMED_OUT flag (and %NL80211_ATTR_MAC to indicate which
213  *      pending authentication timed out).
214  * @NL80211_CMD_ASSOCIATE: association request and notification; like
215  *      NL80211_CMD_AUTHENTICATE but for Association and Reassociation
216  *      (similar to MLME-ASSOCIATE.request, MLME-REASSOCIATE.request,
217  *      MLME-ASSOCIATE.confirm or MLME-REASSOCIATE.confirm primitives).
218  * @NL80211_CMD_DEAUTHENTICATE: deauthentication request and notification; like
219  *      NL80211_CMD_AUTHENTICATE but for Deauthentication frames (similar to
220  *      MLME-DEAUTHENTICATION.request and MLME-DEAUTHENTICATE.indication
221  *      primitives).
222  * @NL80211_CMD_DISASSOCIATE: disassociation request and notification; like
223  *      NL80211_CMD_AUTHENTICATE but for Disassociation frames (similar to
224  *      MLME-DISASSOCIATE.request and MLME-DISASSOCIATE.indication primitives).
225  *
226  * @NL80211_CMD_MICHAEL_MIC_FAILURE: notification of a locally detected Michael
227  *      MIC (part of TKIP) failure; sent on the "mlme" multicast group; the
228  *      event includes %NL80211_ATTR_MAC to describe the source MAC address of
229  *      the frame with invalid MIC, %NL80211_ATTR_KEY_TYPE to show the key
230  *      type, %NL80211_ATTR_KEY_IDX to indicate the key identifier, and
231  *      %NL80211_ATTR_KEY_SEQ to indicate the TSC value of the frame; this
232  *      event matches with MLME-MICHAELMICFAILURE.indication() primitive
233  *
234  * @NL80211_CMD_JOIN_IBSS: Join a new IBSS -- given at least an SSID and a
235  *      FREQ attribute (for the initial frequency if no peer can be found)
236  *      and optionally a MAC (as BSSID) and FREQ_FIXED attribute if those
237  *      should be fixed rather than automatically determined. Can only be
238  *      executed on a network interface that is UP, and fixed BSSID/FREQ
239  *      may be rejected. Another optional parameter is the beacon interval,
240  *      given in the %NL80211_ATTR_BEACON_INTERVAL attribute, which if not
241  *      given defaults to 100 TU (102.4ms).
242  * @NL80211_CMD_LEAVE_IBSS: Leave the IBSS -- no special arguments, the IBSS is
243  *      determined by the network interface.
244  *
245  * @NL80211_CMD_MAX: highest used command number
246  * @__NL80211_CMD_AFTER_LAST: internal use
