 118  * @NL80211_CMD_SET_REG: Set current regulatory domain. CRDA sends this command
 119  *      after being queried by the kernel. CRDA replies by sending a regulatory

 130  *      store this as a valid request and then query userspace for it.
 131  *
 132  * @NL80211_CMD_GET_MESH_PARAMS: Get mesh networking properties for the
 133  *      interface identified by %NL80211_ATTR_IFINDEX

 137  *
 138  * @NL80211_CMD_SET_MGMT_EXTRA_IE: Set extra IEs for management frames. The
 139  *      interface is identified with %NL80211_ATTR_IFINDEX and the management
 140  *      frame subtype with %NL80211_ATTR_MGMT_SUBTYPE. The extra IE data to be
 141  *      added to the end of the specified management frame is specified with
 142  *      %NL80211_ATTR_IE. If the command succeeds, the requested data will be
 143  *      added to all specified management frames generated by
 144  *      kernel/firmware/driver.
 145  *      Note: This command has been removed and it is only reserved at this
 146  *      point to avoid re-using existing command number. The functionality this
 147  *      command was planned for has been provided with cleaner design with the
 148  *      option to specify additional IEs in NL80211_CMD_TRIGGER_SCAN,
 149  *      NL80211_CMD_AUTHENTICATE, NL80211_CMD_ASSOCIATE,
 150  *      NL80211_CMD_DEAUTHENTICATE, and NL80211_CMD_DISASSOCIATE.
 151  *
 152  * @NL80211_CMD_GET_SCAN: get scan results
 153  * @NL80211_CMD_TRIGGER_SCAN: trigger a new scan with the given parameters
 154  * @NL80211_CMD_NEW_SCAN_RESULTS: scan notification (as a reply to
 155  *      NL80211_CMD_GET_SCAN and on the "scan" multicast group)
 156  * @NL80211_CMD_SCAN_ABORTED: scan was aborted, for unspecified reasons,
 157  *      partial scan results may be available
 158  *
 159  * @NL80211_CMD_REG_CHANGE: indicates to userspace the regulatory domain
 160  *      has been changed and provides details of the request information
 161  *      that caused the change such as who initiated the regulatory request
 162  *      (%NL80211_ATTR_REG_INITIATOR), the wiphy_idx
 163  *      (%NL80211_ATTR_REG_ALPHA2) on which the request was made from if
 164  *      the initiator was %NL80211_REGDOM_SET_BY_COUNTRY_IE or
 165  *      %NL80211_REGDOM_SET_BY_DRIVER, the type of regulatory domain
 166  *      set (%NL80211_ATTR_REG_TYPE), if the type of regulatory domain is
 167  *      %NL80211_REG_TYPE_COUNTRY the alpha2 to which we have moved on
 168  *      to (%NL80211_ATTR_REG_ALPHA2).
 169  *
 170  * @NL80211_CMD_AUTHENTICATE: authentication request and notification.
 171  *      This command is used both as a command (request to authenticate) and
 172  *      as an event on the "mlme" multicast group indicating completion of the
 173  *      authentication process.
 174  *      When used as a command, %NL80211_ATTR_IFINDEX is used to identify the
 175  *      interface. %NL80211_ATTR_MAC is used to specify PeerSTAAddress (and
 176  *      BSSID in case of station mode). %NL80211_ATTR_SSID is used to specify
 177  *      the SSID (mainly for association, but is included in authentication
 178  *      request, too, to help BSS selection. %NL80211_ATTR_WIPHY_FREQ is used
 179  *      to specify the frequence of the channel in MHz. %NL80211_ATTR_AUTH_TYPE
 180  *      is used to specify the authentication type. %NL80211_ATTR_IE is used to
 181  *      define IEs (VendorSpecificInfo, but also including RSN IE and FT IEs)
 182  *      to be added to the frame.
 183  *      When used as an event, this reports reception of an Authentication
 184  *      frame in station and IBSS modes when the local MLME processed the
 185  *      frame, i.e., it was for the local STA and was received in correct
 186  *      state. This is similar to MLME-AUTHENTICATE.confirm primitive in the
 187  *      MLME SAP interface (kernel providing MLME, userspace SME). The
 188  *      included NL80211_ATTR_FRAME attribute contains the management frame
 189  *      (including both the header and frame body, but not FCS).
 190  * @NL80211_CMD_ASSOCIATE: association request and notification; like
 191  *      NL80211_CMD_AUTHENTICATE but for Association and Reassociation
 192  *      (similar to MLME-ASSOCIATE.request, MLME-REASSOCIATE.request,
 193  *      MLME-ASSOCIATE.confirm or MLME-REASSOCIATE.confirm primitives).
 194  * @NL80211_CMD_DEAUTHENTICATE: deauthentication request and notification; like
 195  *      NL80211_CMD_AUTHENTICATE but for Deauthentication frames (similar to
 196  *      MLME-DEAUTHENTICATION.request and MLME-DEAUTHENTICATE.indication
 197  *      primitives).
 198  * @NL80211_CMD_DISASSOCIATE: disassociation request and notification; like
 199  *      NL80211_CMD_AUTHENTICATE but for Disassociation frames (similar to
 200  *      MLME-DISASSOCIATE.request and MLME-DISASSOCIATE.indication primitives).
 201  *
 202  * @NL80211_CMD_MICHAEL_MIC_FAILURE: notification of a locally detected Michael
 203  *      MIC (part of TKIP) failure; sent on the "mlme" multicast group; the
 204  *      event includes %NL80211_ATTR_MAC to describe the source MAC address of
 205  *      the frame with invalid MIC, %NL80211_ATTR_KEY_TYPE to show the key
 206  *      type, %NL80211_ATTR_KEY_IDX to indicate the key identifier, and
 207  *      %NL80211_ATTR_KEY_SEQ to indicate the TSC value of the frame; this
 208  *      event matches with MLME-MICHAELMICFAILURE.indication() primitive
 209  *
 210  * @NL80211_CMD_MAX: highest used command number
 211  * @__NL80211_CMD_AFTER_LAST: internal use
