/* * Wavelan Pcmcia driver * * Jean II - HPLB '96 * * Reorganisation and extension of the driver. * * This file contain all definition and declarations necessary for the * wavelan pcmcia driver. This file is a private header, so it should * be included only on wavelan_cs.c !!! */ #ifndef WAVELAN_CS_P_H #define WAVELAN_CS_P_H /************************** DOCUMENTATION **************************/ /* * This driver provide a Linux interface to the Wavelan Pcmcia hardware * The Wavelan is a product of Lucent (http://www.wavelan.com/). * This division was formerly part of NCR and then AT&T. * Wavelan are also distributed by DEC (RoamAbout DS)... * * To know how to use this driver, read the PCMCIA HOWTO. * If you want to exploit the many other fonctionalities, look comments * in the code... * * This driver is the result of the effort of many peoples (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 WAVELAN_ROAMING, for the experimental roaming support. * 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_cs.o is darn too big * ------------------------- * That's true ! There is a very simple way to reduce the driver * object by 33% (yes !). 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 of the wavelan chech that the first 3 * octets of the MAC address fit the company code. This type of * detection work well for AT&T cards (because the AT&T code is * hardcoded in wavelan_cs.h), but of course will fail for other * manufacturer. * * 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, ...) * 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_cs.h) * 3) Compile & verify * 4) Send me the MAC code - I will include it in the next version... * */ /* --------------------- WIRELESS EXTENSIONS --------------------- */ /* * This driver is the first one to support "wireless extensions". * This set of extensions provide you some way to control the wireless * caracteristics of the hardware in a standard way and support for * applications for taking advantage of it (like Mobile IP). * * It might be a good idea as well to fetch the wireless tools to * configure the device and play a bit. */ /* ---------------------------- FILES ---------------------------- */ /* * wavelan_cs.c : The actual code for the driver - C functions * * wavelan_cs.p.h : Private header : local types / vars for the driver * * wavelan_cs.h : Description of the hardware interface & structs * * i82593.h : Description if the Ethernet controller */ /* --------------------------- HISTORY --------------------------- */ /* * The history of the Wavelan drivers is as complicated as history of * the Wavelan itself (NCR -> AT&T -> Lucent). * * 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 modify this for the Pcmcia hardware. * * Robert Morris <rtm@das.harvard.edu> port these two drivers to BSDI * and add specific Pcmcia support (there is currently no equivalent * of the PCMCIA package under BSD...). * * Jim Binkley <jrb@cs.pdx.edu> port both BSDI drivers to FreeBSD. * * Bruce Janson <bruce@cs.usyd.edu.au> port the BSDI ISA driver to Linux. * * Anthony D. Joseph <adj@lcs.mit.edu> started modify Bruce driver * (with help of the BSDI PCMCIA driver) for PCMCIA. * Yunzhou Li <yunzhou@strat.iol.unh.edu> finished is work. * Joe Finney <joe@comp.lancs.ac.uk> patched the driver to start * correctly 2.00 cards (2.4 GHz with frequency selection). * David Hinds <dahinds@users.sourceforge.net> integrated the whole in his * Pcmcia package (+ bug corrections). * * I (Jean Tourrilhes - jt@hplb.hpl.hp.com) then started to make some * patchs to the Pcmcia driver. After, I added code in the ISA driver * for Wireless Extensions and full support of frequency selection * cards. Now, I'm doing the same to the Pcmcia driver + some * reorganisation. * Loeke Brederveld <lbrederv@wavelan.com> from Lucent has given me * much needed informations on the Wavelan hardware. */ /* By the way : for the copyright & legal stuff : * Almost everybody wrote code under GNU or BSD license (or alike), * and want that their original copyright remain somewhere in the * code (for myself, I go with the GPL). * Nobody want to take responsibility for anything, except the fame... */ /* --------------------------- CREDITS --------------------------- */ /* * Credits: * Special thanks to Jan Hoogendoorn of AT&T GIS Utrecht and * Loeke Brederveld of Lucent for providing extremely useful * information about WaveLAN PCMCIA hardware * * This driver is based upon several other drivers, in particular: * David Hinds' Linux driver for the PCMCIA 3c589 ethernet adapter * Bruce Janson's Linux driver for the AT-bus WaveLAN adapter * Anders Klemets' PCMCIA WaveLAN adapter driver * Robert Morris' BSDI driver for the PCMCIA WaveLAN adapter * * Additional Credits: * * This software was originally developed under Linux 1.2.3 * (Slackware 2.0 distribution). * And then under Linux 2.0.x (Debian 1.1 -> 2.2 - pcmcia 2.8.18+) * with an HP OmniBook 4000 and then a 5500. * * It is based on other device drivers and information either written * or supplied by: * James Ashton (jaa101@syseng.anu.edu.au), * Ajay Bakre (bakre@paul.rutgers.edu), * Donald Becker (becker@super.org), * Jim Binkley <jrb@cs.pdx.edu>, * Loeke Brederveld <lbrederv@wavelan.com>, * Allan Creighton (allanc@cs.su.oz.au), * Brent Elphick <belphick@uwaterloo.ca>, * Joe Finney <joe@comp.lancs.ac.uk>, * Matthew Geier (matthew@cs.su.oz.au), * Remo di Giovanni (remo@cs.su.oz.au), * Mark Hagan (mhagan@wtcpost.daytonoh.NCR.COM), * David Hinds <dahinds@users.sourceforge.net>, * Jan Hoogendoorn (c/o marteijn@lucent.com), * Bruce Janson <bruce@cs.usyd.edu.au>, * Anthony D.
