Linux-2.6.12-rc2v2.6.12-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!

+ *                
+ * Filename:      netwave_cs.c
+ * Version:       0.4.1
+ * Description:   Netwave AirSurfer Wireless LAN PC Card driver
+ * Status:        Experimental.
+ * Authors:       John Markus Bjørndalen <johnm@cs.uit.no>
+ *                Dag Brattli <dagb@cs.uit.no>
+ *                David Hinds <dahinds@users.sourceforge.net>
+ * Created at:    A long time ago!
+ * Modified at:   Mon Nov 10 11:54:37 1997
+ * Modified by:   Dag Brattli <dagb@cs.uit.no>

+ *
+ * Revision History:
+ *
+ *   08-Nov-97 15:14:47   John Markus Bjørndalen <johnm@cs.uit.no>
+ *    - Fixed some bugs in netwave_rx and cleaned it up a bit. 
+ *      (One of the bugs would have destroyed packets when receiving
+ *      multiple packets per interrupt). 
+ *    - Cleaned up parts of newave_hw_xmit. 
+ *    - A few general cleanups. 
+ *   24-Oct-97 13:17:36   Dag Brattli <dagb@cs.uit.no>
+ *    - Fixed netwave_rx receive function (got updated docs)
+ *   Others:
+ *    - Changed name from xircnw to netwave, take a look at 
+ *      http://www.netwave-wireless.com
+ *    - Some reorganizing of the code
+ *    - Removed possible race condition between interrupt handler and transmit
+ *      function
+ *    - Started to add wireless extensions, but still needs some coding
+ *    - Added watchdog for better handling of transmission timeouts 
+ *      (hopefully this works better)
