    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

    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

    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_GET_SURVEY: get survey resuls, e.g. channel occupation
    164  *      or noise level
    165  * @NL80211_CMD_NEW_SURVEY_RESULTS: survey data notification (as a reply to
    166  *	NL80211_CMD_GET_SURVEY and on the "scan" multicast group)
    167  *
    168  * @NL80211_CMD_REG_CHANGE: indicates to userspace the regulatory domain
    169  * 	has been changed and provides details of the request information
    170  * 	that caused the change such as who initiated the regulatory request
    171  * 	(%NL80211_ATTR_REG_INITIATOR), the wiphy_idx
    172  * 	(%NL80211_ATTR_REG_ALPHA2) on which the request was made from if
    173  * 	the initiator was %NL80211_REGDOM_SET_BY_COUNTRY_IE or
    174  * 	%NL80211_REGDOM_SET_BY_DRIVER, the type of regulatory domain
    175  * 	set (%NL80211_ATTR_REG_TYPE), if the type of regulatory domain is
    176  * 	%NL80211_REG_TYPE_COUNTRY the alpha2 to which we have moved on
    177  * 	to (%NL80211_ATTR_REG_ALPHA2).
    178  * @NL80211_CMD_REG_BEACON_HINT: indicates to userspace that an AP beacon
    179  * 	has been found while world roaming thus enabling active scan or
    180  * 	any mode of operation that initiates TX (beacons) on a channel
    181  * 	where we would not have been able to do either before. As an example
    182  * 	if you are world roaming (regulatory domain set to world or if your
    183  * 	driver is using a custom world roaming regulatory domain) and while
    184  * 	doing a passive scan on the 5 GHz band you find an AP there (if not
    185  * 	on a DFS channel) you will now be able to actively scan for that AP
    186  * 	or use AP mode on your card on that same channel. Note that this will
    187  * 	never be used for channels 1-11 on the 2 GHz band as they are always
    188  * 	enabled world wide. This beacon hint is only sent if your device had
    189  * 	either disabled active scanning or beaconing on a channel. We send to
    190  * 	userspace the wiphy on which we removed a restriction from
    191  * 	(%NL80211_ATTR_WIPHY) and the channel on which this occurred
    192  * 	before (%NL80211_ATTR_FREQ_BEFORE) and after (%NL80211_ATTR_FREQ_AFTER)
    193  * 	the beacon hint was processed.
    194  *
    195  * @NL80211_CMD_AUTHENTICATE: authentication request and notification.
    196  *	This command is used both as a command (request to authenticate) and
    197  *	as an event on the "mlme" multicast group indicating completion of the
    198  *	authentication process.
    199  *	When used as a command, %NL80211_ATTR_IFINDEX is used to identify the
    200  *	interface. %NL80211_ATTR_MAC is used to specify PeerSTAAddress (and
    201  *	BSSID in case of station mode). %NL80211_ATTR_SSID is used to specify
    202  *	the SSID (mainly for association, but is included in authentication
    203  *	request, too, to help BSS selection. %NL80211_ATTR_WIPHY_FREQ is used
    204  *	to specify the frequence of the channel in MHz. %NL80211_ATTR_AUTH_TYPE
    205  *	is used to specify the authentication type. %NL80211_ATTR_IE is used to
    206  *	define IEs (VendorSpecificInfo, but also including RSN IE and FT IEs)
    207  *	to be added to the frame.
    208  *	When used as an event, this reports reception of an Authentication
    209  *	frame in station and IBSS modes when the local MLME processed the
    210  *	frame, i.e., it was for the local STA and was received in correct
    211  *	state. This is similar to MLME-AUTHENTICATE.confirm primitive in the
    212  *	MLME SAP interface (kernel providing MLME, userspace SME). The
    213  *	included %NL80211_ATTR_FRAME attribute contains the management frame
    214  *	(including both the header and frame body, but not FCS). This event is
    215  *	also used to indicate if the authentication attempt timed out. In that
    216  *	case the %NL80211_ATTR_FRAME attribute is replaced with a
    217  *	%NL80211_ATTR_TIMED_OUT flag (and %NL80211_ATTR_MAC to indicate which
    218  *	pending authentication timed out).
    219  * @NL80211_CMD_ASSOCIATE: association request and notification; like
    220  *	NL80211_CMD_AUTHENTICATE but for Association and Reassociation
    221  *	(similar to MLME-ASSOCIATE.request, MLME-REASSOCIATE.request,
    222  *	MLME-ASSOCIATE.confirm or MLME-REASSOCIATE.confirm primitives).
    223  * @NL80211_CMD_DEAUTHENTICATE: deauthentication request and notification; like
    224  *	NL80211_CMD_AUTHENTICATE but for Deauthentication frames (similar to
    225  *	MLME-DEAUTHENTICATION.request and MLME-DEAUTHENTICATE.indication
    226  *	primitives).
    227  * @NL80211_CMD_DISASSOCIATE: disassociation request and notification; like
    228  *	NL80211_CMD_AUTHENTICATE but for Disassociation frames (similar to
    229  *	MLME-DISASSOCIATE.request and MLME-DISASSOCIATE.indication primitives).
    230  *
    231  * @NL80211_CMD_MICHAEL_MIC_FAILURE: notification of a locally detected Michael
    232  *	MIC (part of TKIP) failure; sent on the "mlme" multicast group; the
    233  *	event includes %NL80211_ATTR_MAC to describe the source MAC address of
    234  *	the frame with invalid MIC, %NL80211_ATTR_KEY_TYPE to show the key
    235  *	type, %NL80211_ATTR_KEY_IDX to indicate the key identifier, and
    236  *	%NL80211_ATTR_KEY_SEQ to indicate the TSC value of the frame; this
    237  *	event matches with MLME-MICHAELMICFAILURE.indication() primitive
    238  *
    239  * @NL80211_CMD_JOIN_IBSS: Join a new IBSS -- given at least an SSID and a
    240  *	FREQ attribute (for the initial frequency if no peer can be found)
    241  *	and optionally a MAC (as BSSID) and FREQ_FIXED attribute if those
    242  *	should be fixed rather than automatically determined. Can only be
    243  *	executed on a network interface that is UP, and fixed BSSID/FREQ
    244  *	may be rejected. Another optional parameter is the beacon interval,
    245  *	given in the %NL80211_ATTR_BEACON_INTERVAL attribute, which if not
    246  *	given defaults to 100 TU (102.4ms).
    247  * @NL80211_CMD_LEAVE_IBSS: Leave the IBSS -- no special arguments, the IBSS is
    248  *	determined by the network interface.
    249  *
    250  * @NL80211_CMD_TESTMODE: testmode command, takes a wiphy (or ifindex) attribute
    251  *	to identify the device, and the TESTDATA blob attribute to pass through
    252  *	to the driver.
    253  *
    254  * @NL80211_CMD_CONNECT: connection request and notification; this command
    255  *	requests to connect to a specified network but without separating
    256  *	auth and assoc steps. For this, you need to specify the SSID in a
    257  *	%NL80211_ATTR_SSID attribute, and can optionally specify the association
    258  *	IEs in %NL80211_ATTR_IE, %NL80211_ATTR_AUTH_TYPE, %NL80211_ATTR_MAC,
    259  *	%NL80211_ATTR_WIPHY_FREQ and %NL80211_ATTR_CONTROL_PORT.
    260  *	It is also sent as an event, with the BSSID and response IEs when the
    261  *	connection is established or failed to be established. This can be
    262  *	determined by the STATUS_CODE attribute.
    263  * @NL80211_CMD_ROAM: request that the card roam (currently not implemented),
    264  *	sent as an event when the card/driver roamed by itself.
    265  * @NL80211_CMD_DISCONNECT: drop a given connection; also used to notify
    266  *	userspace that a connection was dropped by the AP or due to other
    267  *	reasons, for this the %NL80211_ATTR_DISCONNECTED_BY_AP and
    268  *	%NL80211_ATTR_REASON_CODE attributes are used.
    269  *
    270  * @NL80211_CMD_SET_WIPHY_NETNS: Set a wiphy's netns. Note that all devices
    271  *	associated with this wiphy must be down and will follow.
    272  *
    273  * @NL80211_CMD_MAX: highest used command number
    274  * @__NL80211_CMD_AFTER_LAST: internal use
