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 Library 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., 59 Temple Place, Suite 330, Boston, MA 02111-1307 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. + + <signature of Ty Coon>, 1 April 1989 + Ty Coon, President of Vice + +This General Public License does not permit incorporating your program into +proprietary programs.

For most users this would be + sufficient to start working with rt2x00. + +=================== + 3.3: Build +========= + + To build all rt2x00 components which were enabled in the configuration file + simply run (root privileges not required): + + # $ make + + All modules (.ko files) will be created in the current directory. + +=================== + 3.4: Installation +========= + + All rt2x00 modules can be installed by doing (with root privileges): + + # $ make install + + With this command all rt2x00 modules (including rfkill and d80211) will be + created in a newly created folder named 'rt2x00' inside the kernel modules + directory (usually '/lib/modules/$(uname -r)/'). + + +============================================================================== + 4: Firmware +======================================= + +=================== + 4.1: Firmware files +========= + + rt61pci and rt73usb require firmware to be available while loading the module. + The following firmware files are available for each driver: + + # rt61pci + - rt2561.bin + - rt2561s.bin + - rt2661.bin + + # rt73usb + - rt73.bin + +=================== + 4.2: Firmware installation +========= + + The latest firmware files are available in a separate .zip archive and can be + downloaded from the support page on the Ralink website at + http://www.ralinktech.com. + Note that by a high level of logic, Ralink has named their firmware for rt73 + chipsets "rt71W" with a comment that it is for the rt2571W and rt2671 devices. + For rt61pci 3 seperate firmware files are available, which one is used depends + on which RT chip is on the device. Usually it is best to install all files. + To install the firmware the firmware files need to be manually copied to the + systems firmware folder (usually '/lib/firmware/') the exact folder depends + on the distribution. When in doubt consult the distributions documentation. + +=================== + 4.3: Firmware requirements +========= + + To load firmware when the module is loaded the hotplug daemon should be + running. Make sure you either enable hotplugging manually before loading the + module, or make sure hotplugging is enabled during the system boot process. + + +============================================================================== + 5: Module loading +======================================= + +=================== + 5.1: Module load order +========= + + When the modules have been properly installed by following the installation + instructions from the previous section, the module handlers (i.e. modprobe) + will automaticly resolve all module dependencies when loading the device + specific driver. + + When loading the modules manually with insmod, you should load them in the + following order: + + # eeprom_93cx6.ko (optional, only required for pci devices) + # rt2x00lib.ko + # rt2x00pci.ko (optional, only required for pci devices) + # rt2x00usb.ko (optional, only required for usb devices) + # rt2400pci.ko (optional, only required for rt2400 support) + # rt2500pci.ko (optional, only required for rt2500 support) + # rt2500usb.ko (optional, only required for rt2570 support) + # rt61pci.ko (optional, only required for rt61 support) + # rt73usb.ko (optional, only required for rt73 support) + +=================== + 5.2: Module load options +========= + + None. + + +============================================================================== + 6: Interfaces +======================================= + +=================== + 6.1: Wireless interfaces +========= + + After loading the modules two interfaces will now be visible in ifconfig and + iwconfig, namely wmaster0 and wlan0. The first device is the so called master + device which is can be used by some userspace tools, but normally can be + ignored by the user. The second interface wlan0 is the client interface which + the user can configure. + With rt2x00 it is possible to run multiple client interfaces with + only a single device. 1 client interface can run in adhoc, managed or master + mode while a second interface can run in monitor mode at the same time. + More client interfaces can be added by issuing the following command + (with root privileges): + + # $ echo -n <name> > /sys/class/ieee80211/<dev>/add_iface + + where the variable <name> is the name of the client interface that should be + added (i.e. wlan1), and <dev> is the physical device where the new client + interface should be attached to (i.e. phy0). + +=================== + 6.2: Input interface +========= + + When the rfkill driver is being used a new input device with the name of the + device specific module where the button belongs to will have been created. + Whenever the user presses the hardware button the rfkill driver will + automatically make sure the hardware radio is being disabled or enabled + accordingly. When the user has opened the input device the radio will + not be automatically controlled, but instead the input device will + report all button events (KEY_RFKILL) to userspace where the user + could have setup script to do all the work that has to be executed. + This means that while the input device is opened, the user is responsible + for the correct behaviour. + + +============================================================================== + 7: Interface configuration +======================================= + +=================== + 7.1: Minimal configuration +========= + + - After loading the modules the interface should be configured to start + an association or work in monitor mode. The following steps are required + for a minimal configuration to associate with a non-encrypted access point. + + - Before bringing the client interface up, the working mode should be set: + + # $ iwconfig wlan0 mode managed + + - Configuration parts like essid and channel can be set before or after the + client interface has been brought up. + + - It is usually a good idea to set the essid: + + # $ iwconfig wlan0 essid myessid + + - In some situations the device also requires the channel to be manually set: + + # $ iwconfig wlan0 channel mychannel + + - To bring the client interface up: + + # $ ifconfig wlan0 up + + - After the client interface has been brought up, scanning can be performed + to check if the desired AP is being detected. + + # $ iwlist wlan0 scan + + - To start an association attempt, the AP address should be set: + + # $ iwconfig wlan0 ap mybssid + +=================== + 7.2: Configuration tools +========= + + To configure the interface several tools are possible, the most basic tools + are the wireless-tools that provide the iwconfig, iwpriv and iwlist commands. + For WPA connections the wireless-tools are not sufficient, to configure the + interface for WPA wireless network wpa_supplicant is required. + For master mode functionality it is possible to only use the wireless-tools, + but it is recommended to use hostapd instead. This tool offers the best + functionality. + For all configuration tools (wireless-tools, wpa_supplicant and hostapd) are + manuals and howto's present in the manpages or on the internet. It is adviced + to have at least read the manpages before using the tools for a better + understanding on configuring the interface. + + +============================================================================== + 8: Distribution specific notes +======================================= + +=================== + 8.1: Debian & derivatives +========= + + In some instances installing the rt2x00 drivers on debian will result + in the problem that the files are being copied into the wrong folder, + which results in the fact that the driver cannot be loaded. + Installing the drivers should be done manually in this case, + please refer to the distributions documentation regarding the proper + location of the kernel modules. + +=================== + 8.2: Fedora +========= + + Although rt2x00 contains many backward compatibility fixes to ensure + that all rt2x00 components will be able to compile and run on all + systems that meet the minimal requirements, this does not work in all + situations when the Fedora kernels are being used. + The problem lies in the fact that Fedora (like most other distributions) + heavily patch their kernel for better stability and more features. + Unlike the other distributions however, Fedora does not pay attention to + compatibility for external kernel drivers. This means that compiling rt2x00 + while using a Fedora kernel will result in compile errors regarding unknown + fields in structures or problems with function arguments. + For rt2x00 it is impossible to make all checks to support all Fedora kernel + releases. This means that when rt2x00 compilation is failing while using a + Fedora kernel we cannot give support for the compilation steps. + We recommend the user to complain to the Fedora developers when this problem + occurs. + If the user has managed to compile rt2x00 for a Fedora kernel we will + give support for possible problems while working with rt2x00. So the only + part we do not support is the building of rt2x00. + Please note that when you have edited the rt2x00 code to make it compile, + it is advised to state those changes in bugreports while reporting other + problems with rt2x00. + +=================== + 8.3: Gentoo +========= + + rt2x00 can also be found in portage, both the beta releases and the cvs tree. + Because rt2x00 is still experimental these ebuild are still masked, this means + that before you can emerge them they first have to be unmasked. + Gentoo provides various instructions on how this can be done on their website. + +=================== + 8.4: Mandriva +========= + + In some instances installing the rt2x00 drivers on Mandriva will result + in the problem that the files are being copied into the wrong folder, + which results in the fact that the driver cannot be loaded. + Installing the drivers should be done manually in this case, + please refer to the distributions documentation regarding the proper + location of the kernel modules. + + +============================================================================== + 9: Problems & Troubleshooting +======================================= + +=================== + 9.1: Debug information +========= + + When reporting problems make sure the driver has been compiled with debug + enabled. + If you have done so, the debug output can be found in the output + of 'dmesg' and also in /var/log/messages and /var/log/syslog. + +=================== + 9.2: Debugfs +========= + + rt2x00 provides several debugfs entries which can be used to help + provide more information about the interface. + To see the rt2x00 debugfs entries, debugfs should first be mounted, + to do this you should issue the following command: + + # $ mount -t debugfs none /debug + + Where /debug is the directy on which the debugfs entries should appear, + make sure this directory exists when mounting debugfs. + With the debugfs folder, the rt2x00 folder with the rt2x00 debugfs entries + will be created. Within the rt2x00 folder, each physical device will be + represented by a folder named after the interface which belongs to this + device. Within the folder the following files can be found: + + # register + - This file contains the register contents of the interface. + # eeprom + - This file contains the eeprom contents of the interface. + +=================== + 9.3: Bug reporting +========= + + When reporting a bug or problem with the rt2x00 module, + make sure you report the following information: + # How to reproduce + # RT2x00 debug output, usually found in /var/log/messages + # Module version + # Wireless card chipset, model and manufacturer + # Kernel version (i.e. 2.6.17) + # Hardware architecture (i.e. x86, AMD64, Sparc) + # rt2x00 code changes done by the user + # Anything else you may think will help us resolve the issue + + +============================================================================== + 10: Problems & Workarounds +======================================= + +=================== + 10.1: udev interface naming +========= + + In some cases when loading the rt2x00 drivers the interface names are + different from the names used in this README. This is usually caused by the + udev handler who has set some rules regarding the interface. These rules + are usually set up by the distribution and have been created especially for + for the legacy driver and their strange behavior. + To change the rules udev applies to your interface you should edit the udev + rules stored in /etc/udev/rules.d/ (exact location might be different + depending on distribution). + When editing this file, search for the line that contains something like this: + + # ACTION=="add", SUBSYSTEM=="net", DRIVERS=="?*", + # SYSFS{address}=="<mac address>", NAME="<interface>" + (line has been wrapped due to max line length limit) + + Where <mac address> is the hardware address of your wireless networkcard, + and <interface> is the interface name the interface takes as soon as the + rt2x00 modules are loaded. + This line should be changed to look like: + + # ACTION=="add", SUBSYSTEM=="net", DRIVERS=="?*", + # SYSFS{address}=="<mac address>", SYSFS{type}=="801", + # NAME="wmaster0" + # ACTION=="add", SUBSYSTEM=="net", DRIVERS=="?*", + # SYSFS{address}=="<mac address>", NAME="wlan0" + (the 2 lines have been wrapped due to max line length limit) + + Where <mac address> is the hardware address of your wireless networkcard, + and thus should be the same as on the original line. + +=================== + 10.2: BUG - ifdown & ifup radio failure +========= + + It is a known issue (and BUG) that the driver will fail to correctly resume + its radio operations after the interface has been brought down and up again. + It is still unknown what the cause for this issue could be, besides the fact + that for some reason the device's registers have been incorrectly initialized. + This issue also has impact on the device status after a suspend/resume + operation. There is no known workaround for this yet. + + +============================================================================== + 11: TODO list +======================================= + See http://rt2x00.serialmonkey.com/wiki/index.php/Rt2x00_beta + +============================================================================== + 12: Contact us +======================================= + + - Website + # http://rt2x00.serialmonkey.com/ + # http://rt2x00.serialmonkey.com/wiki/index.php/Rt2x00_beta + + - Forums: + # http://rt2x00.serialmonkey.com/phpBB2/ + + - Mailing list: + # general: rt2400-general@lists.sourceforge.net + # developers: rt2400-devel@lists.sourceforge.net + + - Sourceforge: + # http://sourceforge.net/projects/rt2400 + diff --git a/package/rt2x00/src/THANKS b/package/rt2x00/src/THANKS new file mode 100644 index 0000000000..81b88d21f9 --- /dev/null +++ b/package/rt2x00/src/THANKS @@ -0,0 +1,54 @@ +A big thanks to all the developers, testers and supporters of +the rt2x00 Linux source code. + +Thanks to the projects main developers: +* Mark Wallis - mwallis@serialmonkey.com +* Ivo van Doorn - IvDoorn@gmail.com +* Luis Correia - lfcorreia@users.sf.net +* Robin Cornelius - robin.cornelius@gmail.com +* Gertjan van Wingerde - gwingerde@kpnplanet.nl +* Romain - spy84464@hotmail.com + +Special thanks to the contributors of this project: +* Adisorn Ermongkonchai - moo7822-wlan@yahoo.com +* Amir Shalem - amir@boom.org.il +* Bernd Petrovitsch - bernd@firmix.at +* Bruno - bruno123@users.sf.net +* Chris Houston - chris.houston@atterotech.com +* Defekt - defekt@liquid-nexus.net +* Edvard - eaglenest@users.sourceforge.net +* Flavio Stanchina - flavio@stanchina.net +* Gregor Glomm - gg@seh.de +* Heikki Pernu - heikki.pernu@nekonet.fi +* Jerzy Kozera - nordom@tlen.pl +* Joachim Gleißner - jg@suse.de +* John Coppens - john@jcoppens.com +* Jonathan Hudson +* KrissN - krissn@op.pl +* Luca Tettamanti - kronos.it@gmail.com +* Magnus Damm - magnus.damm@gmail.com +* Mags +* Mathias Klien - ma_klein@gmx.de +* Meelis Roos - mroos@linux.ee +* Michal Ludvig - michal@logix.cz +* Miguel - miguel.marte2@verizon.net +* Mike Skinner +* Olivier Cornu - o.cornu@gmail.com +* Paul Hampson - Paul.Hampson@anu.edu.au +* Philippe Rousselot - amazilia@users.sourceforge.net +* Remco - remco@d-compu.dyndns.org +* Sergey Vlasov - vsu@altlinux.ru +* Stephen Warren - SWarren@nvidia.com +* Stuart Rackham - srackham@methods.co.nz +* Thor Harald Johansen - thorhajo@gmail.com +* Tor Petterson - 2r@manowar.dk + +Special thanks: +* Ralink - http://www.ralinktech.com.tw + For releasing their rt2400/rt2500/rt2570 drivers under the GPL, + and their assistance in providing documentation to help development. +* Minitar - www.minitar.com + For working together with Ralink on releasing the + rt2400/rt2500/rt2570 drivers under the GPL. +* All the people that have assisted with the rt2400/rt2500/rt2570 source + and hence progressed the rt2x00 along the way. diff --git a/package/rt2x00/src/config b/package/rt2x00/src/config new file mode 100644 index 0000000000..8a099118b2 --- /dev/null +++ b/package/rt2x00/src/config @@ -0,0 +1,41 @@ +# rt2x00 configuration +# All configuration options can be enabled +# by setting the value to 'y'.
