/************************** 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 .
*
2006-01-21 02:46:55 +03:00
* It might be a good idea as well to fetch the wireless tools to
2005-04-17 02:20:36 +04:00
* 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 .
