+ 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.
+\f
+ 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.)
+\f
+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.
+\f
+ 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.
+\f
+ 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
+\f
+ 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. 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 Library General
+Public License instead of this License.

+
+===============================================================================
+ 1: Minimal requirements:
+=======================================
+
+===================
+ 1.1: kernel
+=========
+
+ - The minimal required kernel version is 2.6.22-rc1
+
+ - It is important that the installed kernel sources match
+ the running kernel. Unless you are crosscompiling and you
+ know what you are doing.
+
+ - Depending on what rt2x00 components will be built,
+ some kernel configuration options are mandatory.
+ It does however not matter if these options are compiled
+ into the kernel or compiled as module.
+
+ Kernel config option Required for component
+ ------------------------------------------------------------------
+ # CONFIG_NET_RADIO all
+ # CONFIG_MAC80211 all
+ # CONFIG_WLAN_80211 all
+ # CONFIG_PCI rt2400pci, rt2500pci, rt61pci
+ # CONFIG_USB rt2500usb, rt73usb
+ # CONFIG_HOTPLUG rt61pci, rt73usb
+ # CONFIG_FW_LOADER rt61pci, rt73usb
+ # CONFIG_CRC_ITU_T rt61pci, rt73usb
+ # CONFIG_DEBUG_FS rt2x00 (optional, only for debug)
+ # CONFIG_RFKILL rt2400pci, rt2500pci, rt61pci (optional,
+ only for button support)
+
+===================
+ 1.2: GCC
+=========
+
+ - For building the rt2x00 components the same gcc version is required
+ as was used to build your target kernel.
+
+===================
+ 1.3: make
+=========
+
+ - The program 'make' needs to be installed on the system. There are no
+ further special requirements for this program.
+
+===============================================================================
+ 2: Hardware
+=======================================
+
+===================
+ 2.1: Chipsets
+=========
+
+ Support for each Ralink wireless chipset has been split into separate drivers.
+
+ # rt2400pci
+ - chipset: rt2400
+ - supports: rt2460
+ - bus type: PCI/PCMCIA/miniPCI
+ # rt2500pci

+ - bus type: PCI/PCMCIA/miniPCI
+ # rt2500usb
+ - chipset: rt2570
+ - supports: rt2570

+===================
+ 2.2: RF button
+=========
+
+ On some occasions the Ralink chipset has been built into a laptop.
+ If that is the case, there usually is a hardware button that controls the
+ radio of the wireless interface.
+ If you have such a hardware device, make sure you enable hardware button
+ support for your device in the configuration before building the rt2x00
+ components.
+ Note: This feature requires the enabling of the rfkill driver in the kernel.
+
+===============================================================================
+ 3: Module building & Installation
+=======================================
+
+===================
+ 3.1: Introduction
+=========
+
+ The following steps in this chapter concerning module building and
+ installation need to be performed for each kernel. 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.
