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)
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
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)

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