4 * Version: 0.4.1
5 * Description: Netwave AirSurfer Wireless LAN PC Card driver
6 * Status: Experimental.
7 * Authors: John Markus Bjørndalen <johnm@cs.uit.no>
8 * Dag Brattli <dagb@cs.uit.no>
9 * David Hinds <dahinds@users.sourceforge.net>
10 * Created at: A long time ago!
11 * Modified at: Mon Nov 10 11:54:37 1997
12 * Modified by: Dag Brattli <dagb@cs.uit.no>
14 * Copyright (c) 1997 University of Tromsø, Norway
16 * Revision History:
18 * 08-Nov-97 15:14:47 John Markus Bjørndalen <johnm@cs.uit.no>
19 * - Fixed some bugs in netwave_rx and cleaned it up a bit.
20 * (One of the bugs would have destroyed packets when receiving
21 * multiple packets per interrupt).
22 * - Cleaned up parts of newave_hw_xmit.
23 * - A few general cleanups.
24 * 24-Oct-97 13:17:36 Dag Brattli <dagb@cs.uit.no>
25 * - Fixed netwave_rx receive function (got updated docs)
26 * Others:
27 * - Changed name from xircnw to netwave, take a look at
28 * http://www.netwave-wireless.com
29 * - Some reorganizing of the code
30 * - Removed possible race condition between interrupt handler and transmit
31 * function
32 * - Started to add wireless extensions, but still needs some coding
33 * - Added watchdog for better handling of transmission timeouts
34 * (hopefully this works better)

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