[PATCH 4/4] netwave: move driver to staging

[John W. Linville]

Move the netwave driver to drivers/staging.  This is another pre-802.11
driver that has seen virtually no non-API-fixup activity in years, and
for which no active hardware is likely to still exist.  This driver
represents unnecessary ongoing maintenance for no clear benefit.

This patch brought to you by the "hacking" session at the 2009 Kernel
Summit in Tokyo, Japan...

- *                Dag Brattli <dagb@xxxxxxxxx>

- *
- * Revision History:
- *
- *   08-Nov-97 15:14:47   John Markus Bjørndalen <johnm@xxxxxxxxx>
- *    - 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@xxxxxxxxx>
- *    - 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)

+ * Modified by:   Dag Brattli <dagb@xxxxxxxxx>

+ *
+ * Revision History:
+ *
+ *   08-Nov-97 15:14:47   John Markus Bjørndalen <johnm@xxxxxxxxx>
+ *    - 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@xxxxxxxxx>
+ *    - 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)
