As an example + * if you are world roaming (regulatory domain set to world or if your + * driver is using a custom world roaming regulatory domain) and while + * doing a passive scan on the 5 GHz band you find an AP there (if not + * on a DFS channel) you will now be able to actively scan for that AP + * or use AP mode on your card on that same channel. Note that this will + * never be used for channels 1-11 on the 2 GHz band as they are always + * enabled world wide. This beacon hint is only sent if your device had + * either disabled active scanning or beaconing on a channel. We send to + * userspace the wiphy on which we removed a restriction from + * (%NL80211_ATTR_WIPHY) and the channel on which this occurred + * before (%NL80211_ATTR_FREQ_BEFORE) and after (%NL80211_ATTR_FREQ_AFTER) + * the beacon hint was processed. + * + * @NL80211_CMD_AUTHENTICATE: authentication request and notification. + * This command is used both as a command (request to authenticate) and + * as an event on the "mlme" multicast group indicating completion of the + * authentication process. + * When used as a command, %NL80211_ATTR_IFINDEX is used to identify the + * interface. %NL80211_ATTR_MAC is used to specify PeerSTAAddress (and + * BSSID in case of station mode). %NL80211_ATTR_SSID is used to specify + * the SSID (mainly for association, but is included in authentication + * request, too, to help BSS selection. %NL80211_ATTR_WIPHY_FREQ is used + * to specify the frequence of the channel in MHz. %NL80211_ATTR_AUTH_TYPE + * is used to specify the authentication type. %NL80211_ATTR_IE is used to + * define IEs (VendorSpecificInfo, but also including RSN IE and FT IEs) + * to be added to the frame. + * When used as an event, this reports reception of an Authentication + * frame in station and IBSS modes when the local MLME processed the + * frame, i.e., it was for the local STA and was received in correct + * state. This is similar to MLME-AUTHENTICATE.confirm primitive in the + * MLME SAP interface (kernel providing MLME, userspace SME). The + * included %NL80211_ATTR_FRAME attribute contains the management frame + * (including both the header and frame body, but not FCS). This event is + * also used to indicate if the authentication attempt timed out. In that + * case the %NL80211_ATTR_FRAME attribute is replaced with a + * %NL80211_ATTR_TIMED_OUT flag (and %NL80211_ATTR_MAC to indicate which + * pending authentication timed out). + * @NL80211_CMD_ASSOCIATE: association request and notification; like + * NL80211_CMD_AUTHENTICATE but for Association and Reassociation + * (similar to MLME-ASSOCIATE.request, MLME-REASSOCIATE.request, + * MLME-ASSOCIATE.confirm or MLME-REASSOCIATE.confirm primitives). + * @NL80211_CMD_DEAUTHENTICATE: deauthentication request and notification; like + * NL80211_CMD_AUTHENTICATE but for Deauthentication frames (similar to + * MLME-DEAUTHENTICATION.request and MLME-DEAUTHENTICATE.indication + * primitives). + * @NL80211_CMD_DISASSOCIATE: disassociation request and notification; like + * NL80211_CMD_AUTHENTICATE but for Disassociation frames (similar to + * MLME-DISASSOCIATE.request and MLME-DISASSOCIATE.indication primitives). + * + * @NL80211_CMD_MICHAEL_MIC_FAILURE: notification of a locally detected Michael + * MIC (part of TKIP) failure; sent on the "mlme" multicast group; the + * event includes %NL80211_ATTR_MAC to describe the source MAC address of + * the frame with invalid MIC, %NL80211_ATTR_KEY_TYPE to show the key + * type, %NL80211_ATTR_KEY_IDX to indicate the key identifier, and + * %NL80211_ATTR_KEY_SEQ to indicate the TSC value of the frame; this + * event matches with MLME-MICHAELMICFAILURE.indication() primitive + * + * @NL80211_CMD_JOIN_IBSS: Join a new IBSS -- given at least an SSID and a + * FREQ attribute (for the initial frequency if no peer can be found) + * and optionally a MAC (as BSSID) and FREQ_FIXED attribute if those + * should be fixed rather than automatically determined. Can only be + * executed on a network interface that is UP, and fixed BSSID/FREQ + * may be rejected. Another optional parameter is the beacon interval, + * given in the %NL80211_ATTR_BEACON_INTERVAL attribute, which if not + * given defaults to 100 TU (102.4ms). + * @NL80211_CMD_LEAVE_IBSS: Leave the IBSS -- no special arguments, the IBSS is + * determined by the network interface. + * + * @NL80211_CMD_TESTMODE: testmode command, takes a wiphy (or ifindex) attribute + * to identify the device, and the TESTDATA blob attribute to pass through + * to the driver. + * + * @NL80211_CMD_CONNECT: connection request and notification; this command + * requests to connect to a specified network but without separating + * auth and assoc steps. For this, you need to specify the SSID in a + * %NL80211_ATTR_SSID attribute, and can optionally specify the association + * IEs in %NL80211_ATTR_IE, %NL80211_ATTR_AUTH_TYPE, %NL80211_ATTR_MAC, + * %NL80211_ATTR_WIPHY_FREQ, %NL80211_ATTR_CONTROL_PORT, + * %NL80211_ATTR_CONTROL_PORT_ETHERTYPE and + * %NL80211_ATTR_CONTROL_PORT_NO_ENCRYPT. + * It is also sent as an event, with the BSSID and response IEs when the + * connection is established or failed to be established. This can be + * determined by the STATUS_CODE attribute. + * @NL80211_CMD_ROAM: request that the card roam (currently not implemented), + * sent as an event when the card/driver roamed by itself. + * @NL80211_CMD_DISCONNECT: drop a given connection; also used to notify + * userspace that a connection was dropped by the AP or due to other + * reasons, for this the %NL80211_ATTR_DISCONNECTED_BY_AP and + * %NL80211_ATTR_REASON_CODE attributes are used. + * + * @NL80211_CMD_SET_WIPHY_NETNS: Set a wiphy's netns. Note that all devices + * associated with this wiphy must be down and will follow. + * + * @NL80211_CMD_REMAIN_ON_CHANNEL: Request to remain awake on the specified + * channel for the specified amount of time. This can be used to do + * off-channel operations like transmit a Public Action frame and wait for + * a response while being associated to an AP on another channel. + * %NL80211_ATTR_IFINDEX is used to specify which interface (and thus + * radio) is used. %NL80211_ATTR_WIPHY_FREQ is used to specify the + * frequency for the operation and %NL80211_ATTR_WIPHY_CHANNEL_TYPE may be + * optionally used to specify additional channel parameters. + * %NL80211_ATTR_DURATION is used to specify the duration in milliseconds + * to remain on the channel. This command is also used as an event to + * notify when the requested duration starts (it may take a while for the + * driver to schedule this time due to other concurrent needs for the + * radio). + * When called, this operation returns a cookie (%NL80211_ATTR_COOKIE) + * that will be included with any events pertaining to this request; + * the cookie is also used to cancel the request. + * @NL80211_CMD_CANCEL_REMAIN_ON_CHANNEL: This command can be used to cancel a + * pending remain-on-channel duration if the desired operation has been + * completed prior to expiration of the originally requested duration. + * %NL80211_ATTR_WIPHY or %NL80211_ATTR_IFINDEX is used to specify the + * radio. The %NL80211_ATTR_COOKIE attribute must be given as well to + * uniquely identify the request. + * This command is also used as an event to notify when a requested + * remain-on-channel duration has expired. + * + * @NL80211_CMD_SET_TX_BITRATE_MASK: Set the mask of rates to be used in TX + * rate selection. %NL80211_ATTR_IFINDEX is used to specify the interface + * and @NL80211_ATTR_TX_RATES the set of allowed rates. + * + * @NL80211_CMD_REGISTER_FRAME: Register for receiving certain mgmt frames + * (via @NL80211_CMD_FRAME) for processing in userspace. This command + * requires an interface index, a frame type attribute (optional for + * backward compatibility reasons, if not given assumes action frames) + * and a match attribute containing the first few bytes of the frame + * that should match, e.g. a single byte for only a category match or + * four bytes for vendor frames including the OUI. The registration + * cannot be dropped, but is removed automatically when the netlink + * socket is closed. Multiple registrations can be made. + * @NL80211_CMD_REGISTER_ACTION: Alias for @NL80211_CMD_REGISTER_FRAME for + * backward compatibility + * @NL80211_CMD_FRAME: Management frame TX request and RX notification. This + * command is used both as a request to transmit a management frame and + * as an event indicating reception of a frame that was not processed in + * kernel code, but is for us (i.e., which may need to be processed in a + * user space application). %NL80211_ATTR_FRAME is used to specify the + * frame contents (including header). %NL80211_ATTR_WIPHY_FREQ (and + * optionally %NL80211_ATTR_WIPHY_CHANNEL_TYPE) is used to indicate on + * which channel the frame is to be transmitted or was received. If this + * channel is not the current channel (remain-on-channel or the + * operational channel) the device will switch to the given channel and + * transmit the frame, optionally waiting for a response for the time + * specified using %NL80211_ATTR_DURATION. When called, this operation + * returns a cookie (%NL80211_ATTR_COOKIE) that will be included with the + * TX status event pertaining to the TX request. + * @NL80211_CMD_FRAME_WAIT_CANCEL: When an off-channel TX was requested, this + * command may be used with the corresponding cookie to cancel the wait + * time if it is known that it is no longer necessary. + * @NL80211_CMD_ACTION: Alias for @NL80211_CMD_FRAME for backward compatibility. + * @NL80211_CMD_FRAME_TX_STATUS: Report TX status of a management frame + * transmitted with %NL80211_CMD_FRAME. %NL80211_ATTR_COOKIE identifies + * the TX command and %NL80211_ATTR_FRAME includes the contents of the + * frame. %NL80211_ATTR_ACK flag is included if the recipient acknowledged + * the frame. + * @NL80211_CMD_ACTION_TX_STATUS: Alias for @NL80211_CMD_FRAME_TX_STATUS for + * backward compatibility. + * @NL80211_CMD_SET_CQM: Connection quality monitor configuration. This command + * is used to configure connection quality monitoring notification trigger + * levels. + * @NL80211_CMD_NOTIFY_CQM: Connection quality monitor notification.
