- /************************** 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
- *
- * 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.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...
- *
- */
- /* --------------------- 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 --------------------------- */
- /*
- * 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@pcmcia.sourceforge.org> 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.
