+                      Version 2, June 1991
+
+ Copyright (C) 1989, 1991 Free Software Foundation, Inc.,
+ 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+                           Preamble
+
+  The licenses for most software are designed to take away your
+freedom to share and change it.  By contrast, the GNU General Public
+License is intended to guarantee your freedom to share and change free
+software--to make sure the software is free for all its users.  This
+General Public License applies to most of the Free Software
+Foundation's software and to any other program whose authors commit to
+using it.  (Some other Free Software Foundation software is covered by
+the GNU Lesser General Public License instead.)  You can apply it to
+your programs, too.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+this service if you wish), that you receive source code or can get it
+if you want it, that you can change the software or use pieces of it
+in new free programs; and that you know you can do these things.
+
+  To protect your rights, we need to make restrictions that forbid
+anyone to deny you these rights or to ask you to surrender the rights.
+These restrictions translate to certain responsibilities for you if you
+distribute copies of the software, or if you modify it.
+
+  For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must give the recipients all the rights that
+you have.  You must make sure that they, too, receive or can get the
+source code.  And you must show them these terms so they know their
+rights.
+
+  We protect your rights with two steps: (1) copyright the software, and
+(2) offer you this license which gives you legal permission to copy,
+distribute and/or modify the software.
+
+  Also, for each author's protection and ours, we want to make certain
+that everyone understands that there is no warranty for this free
+software.  If the software is modified by someone else and passed on, we
+want its recipients to know that what they have is not the original, so
+that any problems introduced by others will not reflect on the original
+authors' reputations.
+
+  Finally, any free program is threatened constantly by software
+patents.  We wish to avoid the danger that redistributors of a free
+program will individually obtain patent licenses, in effect making the
+program proprietary.  To prevent this, we have made it clear that any
+patent must be licensed for everyone's free use or not licensed at all.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+                   GNU GENERAL PUBLIC LICENSE
+   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+  0. This License applies to any program or other work which contains
+a notice placed by the copyright holder saying it may be distributed
+under the terms of this General Public License.  The "Program", below,
+refers to any such program or work, and a "work based on the Program"
+means either the Program or any derivative work under copyright law:
+that is to say, a work containing the Program or a portion of it,
+either verbatim or with modifications and/or translated into another
+language.  (Hereinafter, translation is included without limitation in
+the term "modification".)  Each licensee is addressed as "you".
+
+Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope.  The act of
+running the Program is not restricted, and the output from the Program
+is covered only if its contents constitute a work based on the
+Program (independent of having been made by running the Program).
+Whether that is true depends on what the Program does.
+
+  1. You may copy and distribute verbatim copies of the Program's
+source code as you receive it, in any medium, provided that you
+conspicuously and appropriately publish on each copy an appropriate
+copyright notice and disclaimer of warranty; keep intact all the
+notices that refer to this License and to the absence of any warranty;
+and give any other recipients of the Program a copy of this License
+along with the Program.
+
+You may charge a fee for the physical act of transferring a copy, and
+you may at your option offer warranty protection in exchange for a fee.
+
+  2. You may modify your copy or copies of the Program or any portion
+of it, thus forming a work based on the Program, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+    a) You must cause the modified files to carry prominent notices
+    stating that you changed the files and the date of any change.
+
+    b) You must cause any work that you distribute or publish, that in
+    whole or in part contains or is derived from the Program or any
+    part thereof, to be licensed as a whole at no charge to all third
+    parties under the terms of this License.
+
+    c) If the modified program normally reads commands interactively
+    when run, you must cause it, when started running for such
+    interactive use in the most ordinary way, to print or display an
+    announcement including an appropriate copyright notice and a
+    notice that there is no warranty (or else, saying that you provide
+    a warranty) and that users may redistribute the program under
+    these conditions, and telling the user how to view a copy of this
+    License.  (Exception: if the Program itself is interactive but
+    does not normally print such an announcement, your work based on
+    the Program is not required to print an announcement.)
+
+These requirements apply to the modified work as a whole.  If
+identifiable sections of that work are not derived from the Program,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works.  But when you
+distribute the same sections as part of a whole which is a work based
+on the Program, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Program.
+
+In addition, mere aggregation of another work not based on the Program
+with the Program (or with a work based on the Program) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+  3. You may copy and distribute the Program (or a work based on it,
+under Section 2) in object code or executable form under the terms of
+Sections 1 and 2 above provided that you also do one of the following:
+
+    a) Accompany it with the complete corresponding machine-readable
+    source code, which must be distributed under the terms of Sections
+    1 and 2 above on a medium customarily used for software interchange; or,
+
+    b) Accompany it with a written offer, valid for at least three
+    years, to give any third party, for a charge no more than your
+    cost of physically performing source distribution, a complete
+    machine-readable copy of the corresponding source code, to be
+    distributed under the terms of Sections 1 and 2 above on a medium
+    customarily used for software interchange; or,
+
+    c) Accompany it with the information you received as to the offer
+    to distribute corresponding source code.  (This alternative is
+    allowed only for noncommercial distribution and only if you
+    received the program in object code or executable form with such
+    an offer, in accord with Subsection b above.)
+
+The source code for a work means the preferred form of the work for
+making modifications to it.  For an executable work, complete source
+code means all the source code for all modules it contains, plus any
+associated interface definition files, plus the scripts used to
+control compilation and installation of the executable.  However, as a
+special exception, the source code distributed need not include
+anything that is normally distributed (in either source or binary
+form) with the major components (compiler, kernel, and so on) of the
+operating system on which the executable runs, unless that component
+itself accompanies the executable.
+
+If distribution of executable or object code is made by offering
+access to copy from a designated place, then offering equivalent
+access to copy the source code from the same place counts as
+distribution of the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+  4. You may not copy, modify, sublicense, or distribute the Program
+except as expressly provided under this License.  Any attempt
+otherwise to copy, modify, sublicense or distribute the Program is
+void, and will automatically terminate your rights under this License.
+However, parties who have received copies, or rights, from you under
+this License will not have their licenses terminated so long as such
+parties remain in full compliance.
+
+  5. You are not required to accept this License, since you have not
+signed it.  However, nothing else grants you permission to modify or
+distribute the Program or its derivative works.  These actions are
+prohibited by law if you do not accept this License.  Therefore, by
+modifying or distributing the Program (or any work based on the
+Program), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Program or works based on it.
+
+  6. Each time you redistribute the Program (or any work based on the
+Program), the recipient automatically receives a license from the
+original licensor to copy, distribute or modify the Program subject to
+these terms and conditions.  You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties to
+this License.
+
+  7. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Program at all.  For example, if a patent
+license would not permit royalty-free redistribution of the Program by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Program.
+
+If any portion of this section is held invalid or unenforceable under
+any particular circumstance, the balance of the section is intended to
+apply and the section as a whole is intended to apply in other
+circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system, which is
+implemented by public license practices.  Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+  8. If the distribution and/or use of the Program is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Program under this License
+may add an explicit geographical distribution limitation excluding
+those countries, so that distribution is permitted only in or among
+countries not thus excluded.  In such case, this License incorporates
+the limitation as if written in the body of this License.
+
+  9. The Free Software Foundation may publish revised and/or new versions
+of the General Public License from time to time.  Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+Each version is given a distinguishing version number.  If the Program
+specifies a version number of this License which applies to it and "any
+later version", you have the option of following the terms and conditions
+either of that version or of any later version published by the Free
+Software Foundation.  If the Program does not specify a version number of
+this License, you may choose any version ever published by the Free Software
+Foundation.
+
+  10. If you wish to incorporate parts of the Program into other free
+programs whose distribution conditions are different, write to the author
+to ask for permission.  For software which is copyrighted by the Free
+Software Foundation, write to the Free Software Foundation; we sometimes
+make exceptions for this.  Our decision will be guided by the two goals
+of preserving the free status of all derivatives of our free software and
+of promoting the sharing and reuse of software generally.
+
+                           NO WARRANTY
+
+  11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
+FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN
+OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
+PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
+OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
+MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS
+TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE
+PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
+REPAIR OR CORRECTION.
+
+  12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
+REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
+INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
+OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
+TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
+YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
+PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
+POSSIBILITY OF SUCH DAMAGES.
+
+                    END OF TERMS AND CONDITIONS
+
+           How to Apply These Terms to Your New Programs
+
+  If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+  To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the program's name and a brief idea of what it does.>
+    Copyright (C) <year>  <name of author>
+
+    This program is free software; you can redistribute it and/or modify
+    it under the terms of the GNU General Public License as published by
+    the Free Software Foundation; either version 2 of the License, or
+    (at your option) any later version.
+
+    This program is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
+    GNU General Public License for more details.
+
+    You should have received a copy of the GNU General Public License along
+    with this program; if not, write to the Free Software Foundation, Inc.,
+    51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA.
+
+Also add information on how to contact you by electronic and paper mail.
+
+If the program is interactive, make it output a short notice like this
+when it starts in an interactive mode:
+
+    Gnomovision version 69, Copyright (C) year name of author
+    Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+    This is free software, and you are welcome to redistribute it
+    under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License.  Of course, the commands you use may
+be called something other than `show w' and `show c'; they could even be
+mouse-clicks or menu items--whatever suits your program.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the program, if
+necessary.  Here is a sample; alter the names:
+
+  Yoyodyne, Inc., hereby disclaims all copyright interest in the program
+  `Gnomovision' (which makes passes at compilers) written by James Hacker.

+
+This General Public License does not permit incorporating your program into
+proprietary programs.  If your program is a subroutine library, you may
+consider it more useful to permit linking proprietary applications with the
+library.  If this is what you want to do, use the GNU Lesser General
+Public License instead of this License.

+/**
+ * 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.

+ * is a bit complex though, as there may be a number of restrictions
+ * on the types of concurrency that are supported.
+ *
+ * To start with, each device supports the interface types listed in
+ * the %NL80211_ATTR_SUPPORTED_IFTYPES attribute, but by listing the
+ * types there no concurrency is implied.
+ *
+ * Once concurrency is desired, more attributes must be observed:
+ * To start with, since some interface types are purely managed in
+ * software, like the AP-VLAN type in mac80211 for example, there's
+ * an additional list of these, they can be added at any time and
+ * are only restricted by some semantic restrictions (e.g. AP-VLAN
+ * cannot be added without a corresponding AP interface). This list
+ * is exported in the %NL80211_ATTR_SOFTWARE_IFTYPES attribute.
+ *
+ * Further, the list of supported combinations is exported. This is
+ * in the %NL80211_ATTR_INTERFACE_COMBINATIONS attribute. Basically,
+ * it exports a list of "groups", and at any point in time the
+ * interfaces that are currently active must fall into any one of
+ * the advertised groups. Within each group, there are restrictions
+ * on the number of interfaces of different types that are supported
+ * and also the number of different channels, along with potentially
+ * some other restrictions. See &enum nl80211_if_combination_attrs.

+ *     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

+ *     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

+ *     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

+ *     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

+ *     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

+ *     If included, %NL80211_ATTR_MAC and %NL80211_ATTR_WIPHY_FREQ are
+ *     restrictions on BSS selection, i.e., they effectively prevent roaming
+ *     within the ESS. %NL80211_ATTR_MAC_HINT and %NL80211_ATTR_WIPHY_FREQ_HINT
+ *     can be included to provide a recommendation of the initial BSS while
+ *     allowing the driver to roam to other BSSes within the ESS and also to
+ *     ignore this recommendation if the indicated BSS is not ideal. Only one
+ *     set of BSSID,frequency parameters is used (i.e., either the enforcing
+ *     %NL80211_ATTR_MAC,%NL80211_ATTR_WIPHY_FREQ or the less strict

+ *     This attribute is ignored if driver does not support roam scan.
+ *     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_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

+ *     %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

+ *     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

+ *     and the attributes determining channel width) 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

+ *     inform userspace of the new replay counter.
+ *
+ * @NL80211_CMD_PMKSA_CANDIDATE: This is used as an event to inform userspace
+ *     of PMKSA caching dandidates.
+ *
+ * @NL80211_CMD_TDLS_OPER: Perform a high-level TDLS command (e.g. link setup).
+ *     In addition, this can be used as an event to request userspace to take
+ *     actions on TDLS links (set up a new link or tear down an existing one).
+ *     In such events, %NL80211_ATTR_TDLS_OPERATION indicates the requested

+ *     %NL80211_ATTR_TDLS_ACTION attribute determines the type of frame to be
+ *     sent. Public Action codes (802.11-2012 8.1.5.1) will be sent as
+ *     802.11 management frames, while TDLS action codes (802.11-2012
+ *     8.5.13.1) will be encapsulated and sent as data frames. The currently

+ *
+ * @NL80211_CMD_START_P2P_DEVICE: Start the given P2P Device, identified by
+ *     its %NL80211_ATTR_WDEV identifier. It must have been created with
+ *     %NL80211_CMD_NEW_INTERFACE previously. After it has been started, the
+ *     P2P Device can be used for P2P operations, e.g. remain-on-channel and
+ *     public action frame TX.
+ * @NL80211_CMD_STOP_P2P_DEVICE: Stop the given P2P Device, identified by
+ *     its %NL80211_ATTR_WDEV identifier.
+ *
+ * @NL80211_CMD_CONN_FAILED: connection request to an AP failed; used to

+ *     for IBSS or MESH vif.
+ *
+ * @NL80211_CMD_SET_MAC_ACL: sets ACL for MAC address based access control.
+ *     This is to be used with the drivers advertising the support of MAC
+ *     address based access control. List of MAC addresses is passed in
+ *     %NL80211_ATTR_MAC_ADDRS and ACL policy is passed in
+ *     %NL80211_ATTR_ACL_POLICY. Driver will enable ACL with this list, if it
+ *     is not already done. The new list will replace any existing list. Driver
+ *     will clear its ACL when the list of MAC addresses passed is empty. This
+ *     command is used in AP/P2P GO mode. Driver has to make sure to clear its
+ *     ACL list during %NL80211_CMD_STOP_AP.
+ *
+ * @NL80211_CMD_RADAR_DETECT: Start a Channel availability check (CAC). Once
+ *     a radar is detected or the channel availability scan (CAC) has finished
+ *     or was aborted, or a radar was detected, usermode will be notified with
+ *     this event. This command is also used to notify userspace about radars
+ *     while operating on this channel.
+ *     %NL80211_ATTR_RADAR_EVENT is used to inform about the type of the
+ *     event.
+ *
+ * @NL80211_CMD_GET_PROTOCOL_FEATURES: Get global nl80211 protocol features,
+ *     i.e. features for the nl80211 protocol rather than device features.
+ *     Returns the features in the %NL80211_ATTR_PROTOCOL_FEATURES bitmap.
+ *
+ * @NL80211_CMD_UPDATE_FT_IES: Pass down the most up-to-date Fast Transition
+ *     Information Element to the WLAN driver
+ *
+ * @NL80211_CMD_FT_EVENT: Send a Fast transition event from the WLAN driver
+ *     to the supplicant. This will carry the target AP's MAC address along
+ *     with the relevant Information Elements. This event is used to report
+ *     received FT IEs (MDIE, FTIE, RSN IE, TIE, RICIE).
+ *
+ * @NL80211_CMD_CRIT_PROTOCOL_START: Indicates user-space will start running
+ *     a critical protocol that needs more reliability in the connection to
+ *     complete.
+ *
+ * @NL80211_CMD_CRIT_PROTOCOL_STOP: Indicates the connection reliability can
+ *     return back to normal.
+ *
+ * @NL80211_CMD_GET_COALESCE: Get currently supported coalesce rules.
+ * @NL80211_CMD_SET_COALESCE: Configure coalesce rules or clear existing rules.

+ *     the new channel information (Channel Switch Announcement - CSA)
+ *     in the beacon for some time (as defined in the
+ *     %NL80211_ATTR_CH_SWITCH_COUNT parameter) and then change to the
+ *     new channel. Userspace provides the new channel information (using
+ *     %NL80211_ATTR_WIPHY_FREQ and the attributes determining channel
+ *     width). %NL80211_ATTR_CH_SWITCH_BLOCK_TX may be supplied to inform
+ *     other station that transmission must be blocked until the channel
+ *     switch is complete.
+ *
+ * @NL80211_CMD_VENDOR: Vendor-specified command/event. The command is specified
+ *     by the %NL80211_ATTR_VENDOR_ID attribute and a sub-command in
+ *     %NL80211_ATTR_VENDOR_SUBCMD. Parameter(s) can be transported in
+ *     %NL80211_ATTR_VENDOR_DATA.
+ *     For feature advertisement, the %NL80211_ATTR_VENDOR_DATA attribute is
+ *     used in the wiphy data as a nested attribute containing descriptions
+ *     (&struct nl80211_vendor_cmd_info) of the supported vendor commands.
+ *     This may also be sent as an event with the same attributes.
+ *
+ * @NL80211_CMD_SET_QOS_MAP: Set Interworking QoS mapping for IP DSCP values.
+ *     The QoS mapping information is included in %NL80211_ATTR_QOS_MAP. If
+ *     that attribute is not included, QoS mapping is disabled. Since this
+ *     QoS mapping is relevant for IP packets, it is only valid during an
+ *     association. This is cleared on disassociation and AP restart.

+ * service, and periodically send data to that service. The first data
+ * packet is usually transmitted after SYN/ACK, also ACKing the SYN/ACK.
+ * The data packets can optionally include a (little endian) sequence
+ * number (in the TCP payload!) that is generated by the device, and, also
+ * optionally, a token from a list of tokens. This serves as a keep-alive
+ * with the service, and for NATed connections, etc.
+ *
+ * During this keep-alive period, the server doesn't send any data to the
+ * client. When receiving data, it is compared against the wakeup pattern

+ * connection breaks or cannot be established to start with, the host is
+ * also woken up.

+/*
+ * 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...
