Staging: wavelan: delete the driver 

It has sat in the staging directory since October of 2009, and no one
has stepped up to take it over, so odds are, no one cares about it
anymore.  So, it is now deleted as scheduled, and documented in the TODO
file.

config WAVELAN
tristate "AT&T/Lucent old WaveLAN & DEC RoamAbout DS ISA support"
depends on ISA && WLAN
select WIRELESS_EXT
select WEXT_SPY
select WEXT_PRIV
---help---
The Lucent WaveLAN (formerly NCR and AT&T; or DEC RoamAbout DS) is
a Radio LAN (wireless Ethernet-like Local Area Network) using the
radio frequencies 900 MHz and 2.4 GHz.
If you want to use an ISA WaveLAN card under Linux, say Y and read
the Ethernet-HOWTO, available from
<http://www.tldp.org/docs.html#howto>. Some more specific
information is contained in
<file:Documentation/networking/wavelan.txt> and in the source code
<file:drivers/net/wireless/wavelan.p.h>.
You will also need the wireless tools package available from
<http://www.hpl.hp.com/personal/Jean_Tourrilhes/Linux/Tools.html>.
Please read the man pages contained therein.
To compile this driver as a module, choose M here: the module will be
called wavelan.
config PCMCIA_WAVELAN
tristate "AT&T/Lucent old WaveLAN Pcmcia wireless support"
depends on PCMCIA && WLAN
select WIRELESS_EXT
select WEXT_SPY
select WEXT_PRIV
help
Say Y here if you intend to attach an AT&T/Lucent Wavelan PCMCIA
(PC-card) wireless Ethernet networking card to your computer. This
driver is for the non-IEEE-802.11 Wavelan cards.
To compile this driver as a module, choose M here: the module will be
called wavelan_cs. If unsure, say N.

TODO:
- step up and maintain this driver to ensure that it continues
to work. Having the hardware for this is pretty much a
requirement. If this does not happen, the will be removed in
the 2.6.35 kernel release.
Please send patches to Greg Kroah-Hartman <greg@kroah.com>.

* The description of a later device, the

* Coprocessor", (ibid. p1-38 to p1-109) does mention
* the SCP and ISCP and also has an i82586 compatibility

/************************** DOCUMENTATION ***************************/
/*
* This driver provides a Linux interface to the WaveLAN ISA hardware.
* The WaveLAN is a product of Lucent (http://www.wavelan.com/).
* This division was formerly part of NCR and then AT&T.
* WaveLANs are also distributed by DEC (RoamAbout DS) and Digital Ocean.
*
* To learn how to use this driver, read the NET3 HOWTO.
* If you want to exploit the many other functionalities, read the comments
* in the code.
*
* This driver is the result of the effort of many people (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
*
* SMP
* ---
* We now are SMP compliant (I eventually fixed the remaining bugs).
* The driver has been tested on a dual P6-150 and survived my usual
* set of torture tests.
* Anyway, I spent enough time chasing interrupt re-entrancy during
* errors or reconfigure, and I designed the locked/unlocked sections
* of the driver with great care, and with the recent addition of
* the spinlock (thanks to the new API), we should be quite close to
* the truth.
* The SMP/IRQ locking is quite coarse and conservative (i.e. not fast),
* but better safe than sorry (especially at 2 Mb/s ;-).
*
* I have also looked into disabling only our interrupt on the card
* (via HACR) instead of all interrupts in the processor (via cli),
* so that other driver are not impacted, and it look like it's
* possible, but it's very tricky to do right (full of races). As
* the gain would be mostly for SMP systems, it can wait...
*
* 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 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.o is too darned big
* ---------------------------
* That's true! There is a very simple way to reduce the driver
* object by 33%! 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 for the WaveLAN checks that the first three
* octets of the MAC address fit the company code. This type of
* detection works well for AT&T cards (because the AT&T code is
* hardcoded in wavelan.h), but of course will fail for other
* manufacturers.
*
* 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, etc.)
* 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 and verify
* 4) Send me the MAC code. I will include it in the next version.
*
*/
/* --------------------- WIRELESS EXTENSIONS --------------------- */
/*
* This driver is the first to support "wireless extensions".
* This set of extensions provides a standard way to control the wireless
* characteristics of the hardware. Applications such as mobile IP may
* take advantage of it.
*
* It might be a good idea as well to fetch the wireless tools to
* configure the device and play a bit.

/* --------------------------- HISTORY --------------------------- */
/*
* This is based on information in the drivers' headers. It may not be
* accurate, and I guarantee only my best effort.
*
* The history of the WaveLAN drivers is as complicated as the history of
* the WaveLAN itself (NCR -> AT&T -> Lucent).
*
* It all started with Anders Klemets <klemets@paul.rutgers.edu>
* writing a WaveLAN ISA driver for the Mach microkernel. Girish
* Welling <welling@paul.rutgers.edu> had also worked on it.
* Keith Moore modified this for the PCMCIA hardware.
*
* Robert Morris <rtm@das.harvard.edu> ported these two drivers to BSDI
* and added specific PCMCIA support (there is currently no equivalent
* of the PCMCIA package under BSD).
*
* Jim Binkley <jrb@cs.pdx.edu> ported both BSDI drivers to FreeBSD.
*
* Bruce Janson <bruce@cs.usyd.edu.au> ported the BSDI ISA driver to Linux.
*
* Anthony D. Joseph <adj@lcs.mit.edu> started to modify Bruce's driver
* (with help of the BSDI PCMCIA driver) for PCMCIA.
* Yunzhou Li <yunzhou@strat.iol.unh.edu> finished this work.
* Joe Finney <joe@comp.lancs.ac.uk> patched the driver to start
* 2.00 cards correctly (2.4 GHz with frequency selection).
* David Hinds <dahinds@users.sourceforge.net> integrated the whole in his
* PCMCIA package (and bug corrections).
*
* I (Jean Tourrilhes - jt@hplb.hpl.hp.com) then started to make some
* patches to the PCMCIA driver. Later, I added code in the ISA driver
* for Wireless Extensions and full support of frequency selection
* cards. Then, I did the same to the PCMCIA driver, and did 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 information on the WaveLAN hardware.

* - remove extern keyword for wavelan_probe()
* - level threshold is now a standard wireless extension (version 4 !)
* - modules parameters types (new module interface)
*
* Changes made for release in 2.1.36:
* -----------------------------------
* - byte count stats (courtesy of David Hinds)
* - remove dev_tint stuff (courtesy of David Hinds)
* - encryption setting from Brent Elphick (thanks a lot!)
* - 'ioaddr' to 'u_long' for the Alpha (thanks to Stanislav Sinyagin)
*
* Other changes (not by me) :
* -------------------------
* - Spelling and gramar "rectification".
*
* Changes made for release in 2.0.37 & 2.2.2 :
* ------------------------------------------
* - Correct status in /proc/net/wireless
* - Set PSA CRC to make PtP diagnostic tool happy (Bob Gray)
* - Module init code don't fail if we found at least one card in
* the address list (Karlis Peisenieks)

* - Encryption initialisation bug (Robert McCormack)
* - New mac addresses detected in the probe
* - Increase watchdog for busy environments
*
* Changes made for release in 2.0.38 & 2.2.7 :
* ------------------------------------------
* - Correct the reception logic to better report errors and avoid
* sending bogus packet up the stack
* - Delay RU config to avoid corrupting first received packet
* - Change config completion code (to actually check something)
* - Avoid reading out of bound in skbuf to transmit
* - Rectify a lot of (useless) debugging code
* - Change the way to `#ifdef SET_PSA_CRC'
*
* Changes made for release in 2.2.11 & 2.3.13 :
* -------------------------------------------
* - Change e-mail and web page addresses
* - Watchdog timer is now correctly expressed in HZ, not in jiffies
* - Add channel number to the list of frequencies in range
* - Add the (short) list of bit-rates in range
* - Developp a new sensitivity... (sens.value & sens.fixed)
*
* Changes made for release in 2.2.14 & 2.3.23 :
* -------------------------------------------
* - Fix check for root permission (break instead of exit)
* - New nwid & encoding setting (Wireless Extension 9)
*
* Changes made for release in 2.3.49 :
* ----------------------------------
* - Indentation reformating (Alan)
* - Update to new network API (softnet - 2.3.43) :
* o replace dev->tbusy (Alan)
* o replace dev->tstart (Alan)
* o remove dev->interrupt (Alan)
* o add SMP locking via spinlock in splxx (me)
* o add spinlock in interrupt handler (me)
* o use kernel watchdog instead of ours (me)
* o increase watchdog timeout (kernel is more sensitive) (me)
* o verify that all the changes make sense and work (me)
* - Fixup a potential gotcha when reconfiguring and thighten a bit
* the interactions with Tx queue.
*
* Changes made for release in 2.4.0 :
* ---------------------------------
* - Fix spinlock stupid bugs that I left in. The driver is now SMP
* compliant and doesn't lockup at startup.
*
* Changes made for release in 2.5.2 :
* ---------------------------------
* - Use new driver API for Wireless Extensions :
* o got rid of wavelan_ioctl()
* o use a bunch of iw_handler instead
*
* Changes made for release in 2.5.35 :
* ----------------------------------
* - Set dev->trans_start to avoid filling the logs
* - Handle better spurious/bogus interrupt
* - Avoid deadlocks in mmc_out()/mmc_in()
*
* Wishes & dreams:
* ----------------
* - roaming (see Pcmcia driver)

/************************** 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
*
* SMP
* ---
* We now are SMP compliant (I eventually fixed the remaining bugs).
* The driver has been tested on a dual P6-150 and survived my usual
* set of torture tests.
* Anyway, I spent enough time chasing interrupt re-entrancy during
* errors or reconfigure, and I designed the locked/unlocked sections
* of the driver with great care, and with the recent addition of
* the spinlock (thanks to the new API), we should be quite close to
* the truth.
* The SMP/IRQ locking is quite coarse and conservative (i.e. not fast),
* but better safe than sorry (especially at 2 Mb/s ;-).
*
* I have also looked into disabling only our interrupt on the card
* (via HACR) instead of all interrupts in the processor (via cli),
* so that other driver are not impacted, and it look like it's
* possible, but it's very tricky to do right (full of races). As
* the gain would be mostly for SMP systems, it can wait...
*
* 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_cs.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_cs.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).
*
* It might 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>,
* writing 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 <dahinds@users.sourceforge.net> 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.
