/*
* at76c503-i3863.c:
*
* Driver for at76c503-based devices based on the Atmel "Fast-Vnet" reference
* design using the Intersil 3863 radio chip
*
* Copyright (c) 2002 - 2003 Oliver Kurth <oku@masqmail.cx>
*
* This program is free software; you can redistribute it and/or
* modify it under the terms of the GNU General Public License as
* published by the Free Software Foundation; either version 2 of
* the License, or (at your option) any later version.
*
*
* This driver is derived from usb-skeleton.c
*
* This driver contains code specific to Atmel AT76C503 (USB wireless 802.11)
* devices which use the Intersil 3863 radio chip. Almost all of the actual
* driver is handled by the generic at76c503.c module, this file mostly just
* deals with the initial probes and downloading the correct firmware to the
* device before handing it off to at76c503.
*
* History:
*
* 2003_02_15 0.1: (alex)
* - created 3863-specific driver file
*
* 2003_02_18 0.2: (alex)
* - Reduced duplicated code and moved as much as possible into at76c503.c
* - Changed default netdev name to "wlan%d"
