/************************** DOCUMENTATION **************************/
/*
 * This driver provide a Linux interface to the Wavelan ISA hardware
 * The Wavelan is a product of Lucent ("http://wavelan.netland.nl/").
 * This division was formerly part of NCR and then AT&T.
 * Wavelan are also distributed by DEC (RoamAbout), Digital Ocean and
 * Aironet (Arlan). 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.

/* --------------------------- 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.
