If you have one of those product, you will need to * make some changes below... * * This driver is still a beta software. A lot of bugs have been corrected, * a lot of functionalities are implemented, the whole appear pretty stable, * but there is still some area of improvement (encryption, performance...). * * To know how to use this driver, read the NET3 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 ------------------------ */ /* * wavelan.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> * * 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.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.h) * 3) Compile & verify * 4) Send me the MAC code - I will include it in the next version... * * "CU Inactive" message at boot up : * ----------------------------------- * It seem that there is some weird timings problems with the * Intel microcontroler. In fact, this message is triggered by a * bad reading of the on board ram the first time we read the * control block. If you ignore this message, all is ok (but in * fact, currently, it reset the wavelan hardware). * * To get rid of that problem, there is two solution. The first * is to add a dummy read of the scb at the end of * wv_82586_config. The second is to add the timers * wv_synchronous_cmd and wv_ack (the udelay just after the * waiting loops - seem that the controler is not totally ready * when it say it is !). * * In the current code, I use the second solution (to be * consistent with the original solution of Bruce Janson). */ /* --------------------- 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). * * You will need to enable the CONFIG_NET_RADIO define in the kernel * configuration to enable the wireless extensions (this is the one * giving access to the radio network device choice). * * It might also be a good idea as well to fetch the wireless tools to * configure the device and play a bit. */ /* ---------------------------- FILES ---------------------------- */ /* * wavelan.c : The actual code for the driver - C functions * * wavelan.p.h : Private header : local types / vars for the driver * * wavelan.h : Description of the hardware interface & structs * * i82586.h : Description if the Ethernet controler */ /* --------------------------- HISTORY --------------------------- */ /* * (Made with information in drivers headers. It may not be accurate, * and I garantee nothing except my best effort...) * * 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>, * writting 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 <dhinds@hyper.stanford.edu> 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. Then, I've done the same to the Pcmcia driver + 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 informations on the Wavelan hardware. */ /* The original copyrights and litteratures mention others names and * credits.
