Linux-2.6.12-rc2
Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!

+/************************** 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.
+ *
+ * You will need to enable the CONFIG_NET_RADIO define in the kernel
+ * configuration to enable the wireless extensions (this is the one
+ * giving access to the radio network device choice).
+ *
+ * It might also 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.

+ * code (for myself, I go with the GPL).
