- 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.

- 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>

-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 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:

-
-===============================================================================
- 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
- - chipset: rt2500
- - supports: rt2560
- - bus type: PCI/PCMCIA/miniPCI
- # rt2500usb
- - chipset: rt2570
- - supports: rt2570
- - bus type: USB
- # rt61pci
- - chipset: rt61 (or rt2600)
- - supports: rt2561, rt2561s, rt2661
- - bus type: PCI/PCMCIA/miniPCI
- # rt73usb
- - chipset: rt73
- - supports: rt2571(w), rt2573, rt2671
- - bus type: USB
-
-===================
- 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.
