GNU GENERAL PUBLIC LICENSE - Version 2, June 1991 - - Copyright (C) 1989, 1991 Free Software Foundation, Inc. - 59 Temple Place, Suite 330, Boston, MA 02111-1307 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 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.

This means that - after each kernel upgrade the modules need to be rebuild and - reinstalled in order to make them work with the new kernel. - -=================== - 3.2: Configure -========= - - Before starting to build the rt2x00 components it is recommended to look into - the 'config' file first. In this file you can configure which components of - rt2x00 should be built. And even more importantly, you can configure with - what options the components will be built. - To build all the rt2x00 drivers (with debug capabilities enabled) no changes - in the configuration file are required. 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 deleted file mode 100644 index 81b88d21f9..0000000000 --- a/package/rt2x00/src/THANKS +++ /dev/null @@ -1,54 +0,0 @@ -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/rt2400pci.c b/package/rt2x00/src/rt2400pci.c deleted file mode 100644 index 31c1dd2716..0000000000 --- a/package/rt2x00/src/rt2400pci.c +++ /dev/null @@ -1,1664 +0,0 @@ -/* - Copyright (C) 2004 - 2007 rt2x00 SourceForge Project - <http://rt2x00.serialmonkey.com> - - 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.
