wavelan: move driver to staging
Move the wavelan driver to drivers/staging. This is another pre-802.11 driver that has seen virtually no non-API-fixup activity in years, and for which no active hardware is likely to still exist. This driver represents unnecessary ongoing maintenance for no clear benefit. This patch brought to you by the "hacking" session at the 2009 Kernel Summit in Tokyo, Japan...

17/*
18 * This driver provide a Linux interface to the Wavelan Pcmcia 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 * Wavelan are also distributed by DEC (RoamAbout DS)...
22 *
23 * To know how to use this driver, read the PCMCIA HOWTO.
24 * If you want to exploit the many other fonctionalities, look comments
25 * in the code...
26 *
27 * This driver is the result of the effort of many peoples (see below).

30/* ------------------------ SPECIFIC NOTES ------------------------ */
31/*
32 * Web page
33 * --------
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
36 *
37 * SMP
38 * ---
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
46 * the truth.
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 ;-).
49 *
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...
55 *
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 WAVELAN_ROAMING, for the experimental roaming support.
62 * o SET_PSA_CRC, to have your card correctly recognised by
63 * an access point and the Point-to-Point diagnostic tool.
64 * o USE_PSA_CONFIG, to read configuration from the PSA (EEprom)
65 * (otherwise we always start afresh with some defaults)
66 *
67 * wavelan_cs.o is darn too big
68 * -------------------------
69 * That's true ! There is a very simple way to reduce the driver
70 * object by 33% (yes !). Comment out the following line :
71 * #include <linux/wireless.h>
72 * Other compile options can also reduce the size of it...
73 *
74 * MAC address and hardware detection :
75 * ----------------------------------
76 * The detection code of the wavelan chech that the first 3
77 * octets of the MAC address fit the company code. This type of
78 * detection work well for AT&T cards (because the AT&T code is
79 * hardcoded in wavelan_cs.h), but of course will fail for other
80 * manufacturer.
81 *
82 * If you are sure that your card is derived from the wavelan,
83 * here is the way to configure it :
84 * 1) Get your MAC address
85 * a) With your card utilities (wfreqsel, instconf, ...)
86 * b) With the driver :
87 * o compile the kernel with DEBUG_CONFIG_INFO enabled
88 * o Boot and look the card messages
89 * 2) Set your MAC code (3 octets) in MAC_ADDRESSES[][3] (wavelan_cs.h)
90 * 3) Compile & verify
91 * 4) Send me the MAC code - I will include it in the next version...
92 *
93 */
94
95/* --------------------- WIRELESS EXTENSIONS --------------------- */
96/*
97 * This driver is the first one to support "wireless extensions".
98 * This set of extensions provide you some way to control the wireless
99 * caracteristics of the hardware in a standard way and support for
100 * applications for taking advantage of it (like Mobile IP).
101 *
102 * It might be a good idea as well to fetch the wireless tools to
103 * configure the device and play a bit.

117/* --------------------------- HISTORY --------------------------- */
118/*
119 * The history of the Wavelan drivers is as complicated as history of
120 * the Wavelan itself (NCR -> AT&T -> Lucent).
121 *
122 * All started with Anders Klemets <klemets@paul.rutgers.edu>,
123 * writing a Wavelan ISA driver for the MACH microkernel. Girish
124 * Welling <welling@paul.rutgers.edu> had also worked on it.
125 * Keith Moore modify this for the Pcmcia hardware.
126 *
127 * Robert Morris <rtm@das.harvard.edu> port these two drivers to BSDI
128 * and add specific Pcmcia support (there is currently no equivalent
129 * of the PCMCIA package under BSD...).
130 *
131 * Jim Binkley <jrb@cs.pdx.edu> port both BSDI drivers to FreeBSD.
132 *
133 * Bruce Janson <bruce@cs.usyd.edu.au> port the BSDI ISA driver to Linux.
134 *
135 * Anthony D. Joseph <adj@lcs.mit.edu> started modify Bruce driver
136 * (with help of the BSDI PCMCIA driver) for PCMCIA.
137 * Yunzhou Li <yunzhou@strat.iol.unh.edu> finished is work.
138 * Joe Finney <joe@comp.lancs.ac.uk> patched the driver to start
139 * correctly 2.00 cards (2.4 GHz with frequency selection).
140 * David Hinds <dahinds@users.sourceforge.net> integrated the whole in his
141 * Pcmcia package (+ bug corrections).
142 *
143 * I (Jean Tourrilhes - jt@hplb.hpl.hp.com) then started to make some
144 * patchs to the Pcmcia driver. After, I added code in the ISA driver
145 * for Wireless Extensions and full support of frequency selection
146 * cards. Now, I'm doing the same to the Pcmcia driver + some
147 * reorganisation.
148 * Loeke Brederveld <lbrederv@wavelan.com> from Lucent has given me
149 * much needed informations on the Wavelan hardware.

152/* By the way : for the copyright & legal stuff :
153 * Almost everybody wrote code under GNU or BSD license (or alike),
154 * and want that their original copyright remain somewhere in the
155 * code (for myself, I go with the GPL).
156 * Nobody want to take responsibility for anything, except the fame...
