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...

16/************************** DOCUMENTATION ***************************/
17/*
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.
22 *
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
25 * in the code.
26 *
27 * This driver is the result of the effort of many people (see below).
28 */

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 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)
65 *
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...
72 *
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
79 * manufacturers.
80 *
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.)
85 * b) With the driver:
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.
91 *
92 */
93
94/* --------------------- WIRELESS EXTENSIONS --------------------- */
95/*
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.
100 *
101 * It might be a good idea as well to fetch the wireless tools to
102 * configure the device and play a bit.

116/* --------------------------- HISTORY --------------------------- */
117/*
118 * This is based on information in the drivers' headers. It may not be
119 * accurate, and I guarantee only my best effort.
120 *
121 * The history of the WaveLAN drivers is as complicated as the history of
122 * the WaveLAN itself (NCR -> AT&T -> Lucent).
123 *
124 * It all started with Anders Klemets <klemets@paul.rutgers.edu>
125 * writing a WaveLAN ISA driver for the Mach microkernel. Girish
126 * Welling <welling@paul.rutgers.edu> had also worked on it.
127 * Keith Moore modified this for the PCMCIA hardware.
128 *
129 * Robert Morris <rtm@das.harvard.edu> ported these two drivers to BSDI
130 * and added specific PCMCIA support (there is currently no equivalent
131 * of the PCMCIA package under BSD).
132 *
133 * Jim Binkley <jrb@cs.pdx.edu> ported both BSDI drivers to FreeBSD.
134 *
135 * Bruce Janson <bruce@cs.usyd.edu.au> ported the BSDI ISA driver to Linux.
136 *
137 * Anthony D. Joseph <adj@lcs.mit.edu> started to modify Bruce's driver
138 * (with help of the BSDI PCMCIA driver) for PCMCIA.
139 * Yunzhou Li <yunzhou@strat.iol.unh.edu> finished this work.
140 * Joe Finney <joe@comp.lancs.ac.uk> patched the driver to start
141 * 2.00 cards correctly (2.4 GHz with frequency selection).
142 * David Hinds <dahinds@users.sourceforge.net> integrated the whole in his
143 * PCMCIA package (and bug corrections).
144 *
145 * I (Jean Tourrilhes - jt@hplb.hpl.hp.com) then started to make some
146 * patches to the PCMCIA driver. Later, I added code in the ISA driver
147 * for Wireless Extensions and full support of frequency selection
148 * cards. Then, I did the same to the PCMCIA driver, and did some
149 * reorganisation. Finally, I came back to the ISA driver to
150 * upgrade it at the same level as the PCMCIA one and reorganise
151 * the code.
152 * Loeke Brederveld <lbrederv@wavelan.com> from Lucent has given me
153 * much needed information on the WaveLAN hardware.
