+/**
+ * DOC: Frame transmission/registration support
+ *
+ * Frame transmission and registration support exists to allow userspace
+ * management entities such as wpa_supplicant react to management frames
+ * that are not being handled by the kernel. This includes, for example,
+ * certain classes of action frames that cannot be handled in the kernel
+ * for various reasons.
+ *
+ * Frame registration is done on a per-interface basis and registrations
+ * cannot be removed other than by closing the socket. It is possible to
+ * specify a registration filter to register, for example, only for a
+ * certain type of action frame. In particular with action frames, those
+ * that userspace registers for will not be returned as unhandled by the
+ * driver, so that the registered application has to take responsibility
+ * for doing that.
+ *
+ * The type of frame that can be registered for is also dependent on the
+ * driver and interface type. The frame types are advertised in wiphy
+ * attributes so applications know what to expect.
+ *
+ * NOTE: When an interface changes type while registrations are active,
+ *       these registrations are ignored until the interface type is
+ *       changed again. This means that changing the interface type can
+ *       lead to a situation that couldn't otherwise be produced, but
+ *       any such registrations will be dormant in the sense that they
+ *       will not be serviced, i.e. they will not receive any frames.
+ *
+ * Frame transmission allows userspace to send for example the required
+ * responses to action frames. It is subject to some sanity checking,
+ * but many frames can be transmitted. When a frame was transmitted, its
+ * status is indicated to the sending socket.
+ *
+ * For more technical details, see the corresponding command descriptions
+ * below.

+ * @NL80211_CMD_NEW_SCAN_RESULTS: scan notification (as a reply to
+ *	NL80211_CMD_GET_SCAN and on the "scan" multicast group)
+ * @NL80211_CMD_SCAN_ABORTED: scan was aborted, for unspecified reasons,

+ *
+ * @NL80211_CMD_REG_CHANGE: indicates to userspace the regulatory domain
+ * 	has been changed and provides details of the request information
+ * 	that caused the change such as who initiated the regulatory request
+ * 	(%NL80211_ATTR_REG_INITIATOR), the wiphy_idx
+ * 	(%NL80211_ATTR_REG_ALPHA2) on which the request was made from if
+ * 	the initiator was %NL80211_REGDOM_SET_BY_COUNTRY_IE or
+ * 	%NL80211_REGDOM_SET_BY_DRIVER, the type of regulatory domain
+ * 	set (%NL80211_ATTR_REG_TYPE), if the type of regulatory domain is
+ * 	%NL80211_REG_TYPE_COUNTRY the alpha2 to which we have moved on
+ * 	to (%NL80211_ATTR_REG_ALPHA2).
+ * @NL80211_CMD_REG_BEACON_HINT: indicates to userspace that an AP beacon
+ * 	has been found while world roaming thus enabling active scan or
+ * 	any mode of operation that initiates TX (beacons) on a channel
+ * 	where we would not have been able to do either before. 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. This
+ *	command is used as an event to indicate the that a trigger level was
+ *	reached.
+ * @NL80211_CMD_SET_CHANNEL: Set the channel (using %NL80211_ATTR_WIPHY_FREQ
+ *	and %NL80211_ATTR_WIPHY_CHANNEL_TYPE) the given interface (identifed
+ *	by %NL80211_ATTR_IFINDEX) shall operate on.
+ *	In case multiple channels are supported by the device, the mechanism
+ *	with which it switches channels is implementation-defined.
+ *	When a monitor interface is given, it can only switch channel while
+ *	no other interfaces are operating to avoid disturbing the operation
+ *	of any other interfaces, and other interfaces will again take
+ *	precedence when they are used.
+ *
+ * @NL80211_CMD_SET_WDS_PEER: Set the MAC address of the peer on a WDS interface.
+ *
+ * @NL80211_CMD_JOIN_MESH: Join a mesh. The mesh ID must be given, and initial
+ *	mesh config parameters may be given.
+ * @NL80211_CMD_LEAVE_MESH: Leave the mesh network -- no special arguments, the
+ *	network is determined by the network interface.
+ *
+ * @NL80211_CMD_UNPROT_DEAUTHENTICATE: Unprotected deauthentication frame
+ *	notification. This event is used to indicate that an unprotected
+ *	deauthentication frame was dropped when MFP is in use.
+ * @NL80211_CMD_UNPROT_DISASSOCIATE: Unprotected disassociation frame
+ *	notification. This event is used to indicate that an unprotected
+ *	disassociation frame was dropped when MFP is in use.
+ *
+ * @NL80211_CMD_MAX: highest used command number
+ * @__NL80211_CMD_AFTER_LAST: internal use

+ *	drivers can derive which chainmasks to use (if all antennas belonging to
+ *	a particular chain are disabled this chain should be disabled) and if
+ *	a chain has diversity antennas wether diversity should be used or not.
+ *	HT capabilities (STBC, TX Beamforming, Antenna selection) can be
+ *	derived from the available chains after applying the antenna mask.

+/*
+ * Initial APIs (1996 -> onward) :
+ * -----------------------------
+ * Basically, the wireless extensions are for now a set of standard ioctl
+ * call + /proc/net/wireless
+ *
+ * The entry /proc/net/wireless give statistics and information on the
+ * driver.
+ * This is better than having each driver having its entry because
+ * its centralised and we may remove the driver module safely.
+ *
+ * Ioctl are used to configure the driver and issue commands.  This is
+ * better than command line options of insmod because we may want to
+ * change dynamically (while the driver is running) some parameters.
+ *
+ * The ioctl mechanimsm are copied from standard devices ioctl.
+ * We have the list of command plus a structure descibing the
+ * data exchanged...
+ * Note that to add these ioctl, I was obliged to modify :
+ *	# net/core/dev.c (two place + add include)
+ *	# net/ipv4/af_inet.c (one place + add include)
+ *
+ * /proc/net/wireless is a copy of /proc/net/dev.
+ * We have a structure for data passed from the driver to /proc/net/wireless
+ * Too add this, I've modified :
+ *	# net/core/dev.c (two other places)
+ *	# include/linux/netdevice.h (one place)
+ *	# include/linux/proc_fs.h (one place)
+ *
+ * New driver API (2002 -> onward) :
+ * -------------------------------
+ * This file is only concerned with the user space API and common definitions.
+ * The new driver API is defined and documented in :
+ *	# include/net/iw_handler.h
+ *
+ * Note as well that /proc/net/wireless implementation has now moved in :
+ *	# net/core/wireless.c
+ *
+ * Wireless Events (2002 -> onward) :
+ * --------------------------------
+ * Events are defined at the end of this file, and implemented in :
+ *	# net/core/wireless.c
+ *
+ * Other comments :
+ * --------------
+ * Do not add here things that are redundant with other mechanisms
+ * (drivers init, ifconfig, /proc/net/dev, ...) and with are not
+ * wireless specific.
+ *
+ * These wireless extensions are not magic : each driver has to provide
+ * support for them...
+ *
+ * IMPORTANT NOTE : As everything in the kernel, this is very much a
+ * work in progress. Contact me if you have ideas of improvements...
