| /************************** DOCUMENTATION ***************************/ |
| /* |
| * This driver provides a Linux interface to the WaveLAN ISA hardware. |
| * The WaveLAN is a product of Lucent (http://www.wavelan.com/). |
| * This division was formerly part of NCR and then AT&T. |
| * WaveLANs are also distributed by DEC (RoamAbout DS) and Digital Ocean. |
| * |
| * To learn how to use this driver, read the NET3 HOWTO. |
| * If you want to exploit the many other functionalities, read the comments |
| * in the code. |
| * |
| * This driver is the result of the effort of many people (see below). |
| */ |
| |
| /* ------------------------ SPECIFIC NOTES ------------------------ */ |
| /* |
| * Web page |
| * -------- |
| * I try to maintain a web page with the Wireless LAN Howto at : |
| * http://www.hpl.hp.com/personal/Jean_Tourrilhes/Linux/Wavelan.html |
| * |
| * SMP |
| * --- |
| * We now are SMP compliant (I eventually fixed the remaining bugs). |
| * The driver has been tested on a dual P6-150 and survived my usual |
| * set of torture tests. |
| * Anyway, I spent enough time chasing interrupt re-entrancy during |
| * errors or reconfigure, and I designed the locked/unlocked sections |
| * of the driver with great care, and with the recent addition of |
| * the spinlock (thanks to the new API), we should be quite close to |
| * the truth. |
| * The SMP/IRQ locking is quite coarse and conservative (i.e. not fast), |
| * but better safe than sorry (especially at 2 Mb/s ;-). |
| * |
| * I have also looked into disabling only our interrupt on the card |
| * (via HACR) instead of all interrupts in the processor (via cli), |
| * so that other driver are not impacted, and it look like it's |
| * possible, but it's very tricky to do right (full of races). As |
| * the gain would be mostly for SMP systems, it can wait... |
| * |
| * Debugging and options |
| * --------------------- |
| * You will find below a set of '#define" allowing a very fine control |
| * on the driver behaviour and the debug messages printed. |
| * The main options are : |
| * o SET_PSA_CRC, to have your card correctly recognised by |
| * an access point and the Point-to-Point diagnostic tool. |
| * o USE_PSA_CONFIG, to read configuration from the PSA (EEprom) |
| * (otherwise we always start afresh with some defaults) |
| * |
| * wavelan.o is too darned big |
| * --------------------------- |
| * That's true! There is a very simple way to reduce the driver |
| * object by 33%! Comment out the following line: |
| * #include <linux/wireless.h> |
| * Other compile options can also reduce the size of it... |
| * |
| * MAC address and hardware detection: |
| * ----------------------------------- |
| * The detection code for the WaveLAN checks that the first three |
| * octets of the MAC address fit the company code. This type of |
| * detection works well for AT&T cards (because the AT&T code is |
| * hardcoded in wavelan.h), but of course will fail for other |
| * manufacturers. |
| * |
| * If you are sure that your card is derived from the WaveLAN, |
| * here is the way to configure it: |
| * 1) Get your MAC address |
| * a) With your card utilities (wfreqsel, instconf, etc.) |
| * b) With the driver: |
| * o compile the kernel with DEBUG_CONFIG_INFO enabled |
| * o Boot and look the card messages |
| * 2) Set your MAC code (3 octets) in MAC_ADDRESSES[][3] (wavelan.h) |
| * 3) Compile and verify |
| * 4) Send me the MAC code. I will include it in the next version. |
| * |

| |
| /* --------------------- WIRELESS EXTENSIONS --------------------- */ |
| /* |
| * This driver is the first to support "wireless extensions". |
| * This set of extensions provides a standard way to control the wireless |
| * characteristics of the hardware. Applications such as mobile IP may |
| * take advantage of it. |
| * |
| * It might be a good idea as well to fetch the wireless tools to |
| * configure the device and play a bit. |

| /* --------------------------- HISTORY --------------------------- */ |
| /* |
| * This is based on information in the drivers' headers. It may not be |
| * accurate, and I guarantee only my best effort. |
| * |
| * The history of the WaveLAN drivers is as complicated as the history of |
| * the WaveLAN itself (NCR -> AT&T -> Lucent). |
| * |
| * It all started with Anders Klemets <klemets@paul.rutgers.edu> |
| * writing a WaveLAN ISA driver for the Mach microkernel. Girish |
| * Welling <welling@paul.rutgers.edu> had also worked on it. |
| * Keith Moore modified this for the PCMCIA hardware. |
| * |
| * Robert Morris <rtm@das.harvard.edu> ported these two drivers to BSDI |
| * and added specific PCMCIA support (there is currently no equivalent |
| * of the PCMCIA package under BSD). |
| * |
| * Jim Binkley <jrb@cs.pdx.edu> ported both BSDI drivers to FreeBSD. |
| * |
| * Bruce Janson <bruce@cs.usyd.edu.au> ported the BSDI ISA driver to Linux. |
| * |
| * Anthony D. Joseph <adj@lcs.mit.edu> started to modify Bruce's driver |
| * (with help of the BSDI PCMCIA driver) for PCMCIA. |
| * Yunzhou Li <yunzhou@strat.iol.unh.edu> finished this work. |
| * Joe Finney <joe@comp.lancs.ac.uk> patched the driver to start |
| * 2.00 cards correctly (2.4 GHz with frequency selection). |
| * David Hinds <dahinds@users.sourceforge.net> integrated the whole in his |
| * PCMCIA package (and bug corrections). |
| * |
| * I (Jean Tourrilhes - jt@hplb.hpl.hp.com) then started to make some |
| * patches to the PCMCIA driver. Later, I added code in the ISA driver |
| * for Wireless Extensions and full support of frequency selection |
| * cards. Then, I did the same to the PCMCIA driver, and did some |
| * reorganisation. Finally, I came back to the ISA driver to |
| * upgrade it at the same level as the PCMCIA one and reorganise |
| * the code. |
| * Loeke Brederveld <lbrederv@wavelan.com> from Lucent has given me |
| * much needed information on the WaveLAN hardware. |
