Jan Engelhardt 96de0e252c Convert files to UTF-8 and some cleanups 
* Convert files to UTF-8.

  * Also correct some people's names
    (one example is Eißfeldt, which was found in a source file.
    Given that the author used an ß at all in a source file
    indicates that the real name has in fact a 'ß' and not an 'ss',
    which is commonly used as a substitute for 'ß' when limited to
    7bit.)

  * Correct town names (Goettingen -> Göttingen)

  * Update Eberhard Mönkeberg's address (http://lkml.org/lkml/2007/1/8/313)

/*********************************************************************
*
* 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)

A struct pcmcia_device structure has fields for most things that are needed
to keep track of a socket, but there will usually be some device
specific information that also needs to be kept track of. The
'priv' pointer in a struct pcmcia_device structure can be used to point to
a device-specific private data structure, like this.
A driver needs to provide a dev_node_t structure for each device
on a card. In some cases, there is only one device per card (for
example, ethernet cards, modems). In other cases, there may be
many actual or logical devices (SCSI adapters, memory cards with
multiple partitions). The dev_node_t structures need to be kept
in a linked list starting at the 'dev' field of a struct pcmcia_device
structure. We allocate them in the card's private data structure,
because they generally can't be allocated dynamically.
