6 * Reorganisation and extension of the driver.
8 * This file contains all definitions and declarations necessary for the
9 * WaveLAN ISA driver. This file is a private header, so it should
10 * be included only in wavelan.c!
16 /************************** DOCUMENTATION ***************************/
18 * This driver provides a Linux interface to the WaveLAN ISA hardware.
19 * The WaveLAN is a product of Lucent (http://www.wavelan.com/).
20 * This division was formerly part of NCR and then AT&T.
21 * WaveLANs are also distributed by DEC (RoamAbout DS) and Digital Ocean.
23 * To learn how to use this driver, read the NET3 HOWTO.
24 * If you want to exploit the many other functionalities, read the comments
27 * This driver is the result of the effort of many people (see below).
30 /* ------------------------ SPECIFIC NOTES ------------------------ */
34 * I try to maintain a web page with the Wireless LAN Howto at :
35 * http://www.hpl.hp.com/personal/Jean_Tourrilhes/Linux/Wavelan.html
39 * We now are SMP compliant (I eventually fixed the remaining bugs).
40 * The driver has been tested on a dual P6-150 and survived my usual
41 * set of torture tests.
42 * Anyway, I spent enough time chasing interrupt re-entrancy during
43 * errors or reconfigure, and I designed the locked/unlocked sections
44 * of the driver with great care, and with the recent addition of
45 * the spinlock (thanks to the new API), we should be quite close to
47 * The SMP/IRQ locking is quite coarse and conservative (i.e. not fast),
48 * but better safe than sorry (especially at 2 Mb/s ;-).
50 * I have also looked into disabling only our interrupt on the card
51 * (via HACR) instead of all interrupts in the processor (via cli),
52 * so that other driver are not impacted, and it look like it's
53 * possible, but it's very tricky to do right (full of races). As
54 * the gain would be mostly for SMP systems, it can wait...
56 * Debugging and options
57 * ---------------------
58 * You will find below a set of '#define" allowing a very fine control
59 * on the driver behaviour and the debug messages printed.
60 * The main options are :
61 * o SET_PSA_CRC, to have your card correctly recognised by
62 * an access point and the Point-to-Point diagnostic tool.
63 * o USE_PSA_CONFIG, to read configuration from the PSA (EEprom)
64 * (otherwise we always start afresh with some defaults)
66 * wavelan.o is too darned big
67 * ---------------------------
68 * That's true! There is a very simple way to reduce the driver
69 * object by 33%! Comment out the following line:
70 * #include <linux/wireless.h>
71 * Other compile options can also reduce the size of it...
73 * MAC address and hardware detection:
74 * -----------------------------------
75 * The detection code for the WaveLAN checks that the first three
76 * octets of the MAC address fit the company code. This type of
77 * detection works well for AT&T cards (because the AT&T code is
78 * hardcoded in wavelan.h), but of course will fail for other
81 * If you are sure that your card is derived from the WaveLAN,
82 * here is the way to configure it:
83 * 1) Get your MAC address
84 * a) With your card utilities (wfreqsel, instconf, etc.)
86 * o compile the kernel with DEBUG_CONFIG_INFO enabled
87 * o Boot and look the card messages
88 * 2) Set your MAC code (3 octets) in MAC_ADDRESSES[][3] (wavelan.h)
89 * 3) Compile and verify
90 * 4) Send me the MAC code. I will include it in the next version.
94 /* --------------------- WIRELESS EXTENSIONS --------------------- */
96 * This driver is the first to support "wireless extensions".
97 * This set of extensions provides a standard way to control the wireless
98 * characteristics of the hardware. Applications such as mobile IP may
99 * take advantage of it.
101 * You will need to enable the CONFIG_NET_RADIO define in the kernel
102 * configuration to enable the wireless extensions (this is the one
103 * giving access to the radio network device choice).
105 * It might also be a good idea as well to fetch the wireless tools to
106 * configure the device and play a bit.

120 /* --------------------------- HISTORY --------------------------- */
122 * This is based on information in the drivers' headers. It may not be
123 * accurate, and I guarantee only my best effort.
125 * The history of the WaveLAN drivers is as complicated as the history of
126 * the WaveLAN itself (NCR -> AT&T -> Lucent).
128 * It all started with Anders Klemets <klemets@paul.rutgers.edu>
129 * writing a WaveLAN ISA driver for the Mach microkernel. Girish
130 * Welling <welling@paul.rutgers.edu> had also worked on it.
131 * Keith Moore modified this for the PCMCIA hardware.
133 * Robert Morris <rtm@das.harvard.edu> ported these two drivers to BSDI
134 * and added specific PCMCIA support (there is currently no equivalent
135 * of the PCMCIA package under BSD).
137 * Jim Binkley <jrb@cs.pdx.edu> ported both BSDI drivers to FreeBSD.
139 * Bruce Janson <bruce@cs.usyd.edu.au> ported the BSDI ISA driver to Linux.
141 * Anthony D. Joseph <adj@lcs.mit.edu> started to modify Bruce's driver
142 * (with help of the BSDI PCMCIA driver) for PCMCIA.
143 * Yunzhou Li <yunzhou@strat.iol.unh.edu> finished this work.
144 * Joe Finney <joe@comp.lancs.ac.uk> patched the driver to start
145 * 2.00 cards correctly (2.4 GHz with frequency selection).
146 * David Hinds <dahinds@users.sourceforge.net> integrated the whole in his
147 * PCMCIA package (and bug corrections).
149 * I (Jean Tourrilhes - jt@hplb.hpl.hp.com) then started to make some
150 * patches to the PCMCIA driver. Later, I added code in the ISA driver
151 * for Wireless Extensions and full support of frequency selection
152 * cards. Then, I did the same to the PCMCIA driver, and did some
153 * reorganisation. Finally, I came back to the ISA driver to
154 * upgrade it at the same level as the PCMCIA one and reorganise
156 * Loeke Brederveld <lbrederv@wavelan.com> from Lucent has given me
157 * much needed information on the WaveLAN hardware.
160 /* The original copyrights and literature mention others' names and
161 * credits. I don't know what their part in this development was.
164 /* By the way, for the copyright and legal stuff:
165 * almost everybody wrote code under the GNU or BSD license (or similar),
166 * and want their original copyright to remain somewhere in the

168 * Nobody wants to take responsibility for anything, except the fame.
