|
|
* This driver provide 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 |
|
|
* Wavelan are also distributed by DEC (RoamAbout DS) and Digital Ocean.
|
| 22 |
|
|
*
|
| 23 |
|
|
* To know how to use this driver, read the NET3 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).

/*
|
| 32 |
|
|
* Web page
|
| 33 |
|
|
* --------
|
| 34 |
|
|
* I try to maintain a web page with the Wireless LAN Howto at :
|
| 35 |
|
|
* http://www-uk.hpl.hp.com/people/jt/Linux/Wavelan.html
|
| 36 |
|
|
*
|
| 37 |
|
|
* wavelan.o is darn too big
|
| 38 |
|
|
* -------------------------
|
| 39 |
|
|
* That's true ! There is a very simple way to reduce the driver
|
| 40 |
|
|
* object by 33% (yes !). Comment out the following line :
|
| 41 |
|
|
* #include <linux/wireless.h>
|
| 42 |
|
|
*
|
| 43 |
|
|
* Debugging and options
|
| 44 |
|
|
* ---------------------
|
| 45 |
|
|
* You will find below a set of '#define" allowing a very fine control
|
| 46 |
|
|
* on the driver behaviour and the debug messages printed.
|
| 47 |
|
|
*
|
| 48 |
|
|
* MAC address and hardware detection :
|
| 49 |
|
|
* ----------------------------------
|
| 50 |
|
|
* The detection code of the wavelan chech that the first 3
|
| 51 |
|
|
* octets of the MAC address fit the company code. This type of
|
| 52 |
|
|
* detection work well for AT&T cards (because the AT&T code is
|
| 53 |
|
|
* hardcoded in wavelan.h), but of course will fail for other
|
| 54 |
|
|
* manufacturer.
|
| 55 |
|
|
*
|
| 56 |
|
|
* If you are sure that your card is derived from the wavelan,
|
| 57 |
|
|
* here is the way to configure it :
|
| 58 |
|
|
* 1) Get your MAC address
|
| 59 |
|
|
* a) With your card utilities (wfreqsel, instconf, ...)
|
| 60 |
|
|
* b) With the driver :
|
| 61 |
|
|
* o compile the kernel with DEBUG_CONFIG_INFO enabled
|
| 62 |
|
|
* o Boot and look the card messages
|
| 63 |
|
|
* 2) Set your MAC code (3 octets) in MAC_ADDRESSES[][3] (wavelan.h)
|
| 64 |
|
|
* 3) Compile & verify
|
| 65 |
|
|
* 4) Send me the MAC code - I will include it in the next version...

/* --------------------- WIRELESS EXTENSIONS --------------------- */
|
| 70 |
|
|
/*
|
| 71 |
|
|
* This driver is the first one to support "wireless extensions".
|
| 72 |
|
|
* This set of extensions provide you some way to control the wireless
|
| 73 |
|
|
* caracteristics of the hardware in a standard way and support for
|
| 74 |
|
|
* applications for taking advantage of it (like Mobile IP).
|
| 75 |
|
|
*
|
| 76 |
|
|
* You will need to enable the CONFIG_NET_RADIO define in the kernel
|
| 77 |
|
|
* configuration to enable the wireless extensions (this is the one
|
| 78 |
|
|
* giving access to the radio network device choice).
|
| 79 |
|
|
*
|
| 80 |
|
|
* It might also be a good idea as well to fetch the wireless tools to
|
| 81 |
|
|
* configure the device and play a bit.

| 98 |
|
|
* and I garantee nothing except my best effort...)
|
| 99 |
|
|
*
|
| 100 |
|
|
* The history of the Wavelan drivers is as complicated as history of
|
| 101 |
|
|
* the Wavelan itself (NCR -> AT&T -> Lucent).
|
| 102 |
|
|
*
|
| 103 |
|
|
* All started with Anders Klemets <klemets@paul.rutgers.edu>,
|
| 104 |
|
|
* writting a Wavelan ISA driver for the MACH microkernel. Girish
|
| 105 |
|
|
* Welling <welling@paul.rutgers.edu> had also worked on it.
|
| 106 |
|
|
* Keith Moore modify this for the Pcmcia hardware.
|
| 107 |
|
|
*
|
| 108 |
|
|
* Robert Morris <rtm@das.harvard.edu> port these two drivers to BSDI
|
| 109 |
|
|
* and add specific Pcmcia support (there is currently no equivalent
|
| 110 |
|
|
* of the PCMCIA package under BSD...).
|
| 111 |
|
|
*
|
| 112 |
|
|
* Jim Binkley <jrb@cs.pdx.edu> port both BSDI drivers to freeBSD.
|
| 113 |
|
|
*
|
| 114 |
|
|
* Bruce Janson <bruce@cs.usyd.edu.au> port the BSDI ISA driver to Linux.
|
| 115 |
|
|
*
|
| 116 |
|
|
* Anthony D. Joseph <adj@lcs.mit.edu> started modify Bruce driver
|
| 117 |
|
|
* (with help of the BSDI PCMCIA driver) for PCMCIA.
|
| 118 |
|
|
* Yunzhou Li <yunzhou@strat.iol.unh.edu> finished is work.
|
| 119 |
|
|
* Joe Finney <joe@comp.lancs.ac.uk> patched the driver to start
|
| 120 |
|
|
* correctly 2.00 cards (2.4 GHz with frequency selection).
|
| 121 |
|
|
* David Hinds <dhinds@hyper.stanford.edu> integrated the whole in his
|
| 122 |
|
|
* Pcmcia package (+ bug corrections).
|
| 123 |
|
|
*
|
| 124 |
|
|
* I (Jean Tourrilhes - jt@hplb.hpl.hp.com) then started to make some
|
| 125 |
|
|
* patchs to the Pcmcia driver. After, I added code in the ISA driver
|
| 126 |
|
|
* for Wireless Extensions and full support of frequency selection
|
| 127 |
|
|
* cards. Then, I've done the same to the Pcmcia driver + some
|
| 128 |
|
|
* reorganisation. Finally, I came back to the ISA driver to
|
| 129 |
|
|
* upgrade it at the same level as the Pcmcia one and reorganise
|
| 130 |
|
|
* the code
|
| 131 |
|
|
* Loeke Brederveld <lbrederv@wavelan.com> from Lucent has given me
|
| 132 |
|
|
* much needed informations on the Wavelan hardware.
