- *
- * 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>
- *
- * Copyright (c) 1997 University of Tromsø, Norway
- *
- * 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)

+ *
+ * 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>

+ * Copyright (c) 1997 University of Tromsø, Norway
+ *
+ * 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)
