+ *  tmspci.c: A generic network driver for TMS380-based PCI token ring cards.
+ *
+ *  Written 1999 by Adam Fritzler
+ *
+ *  This software may be used and distributed according to the terms
+ *  of the GNU General Public License, incorporated herein by reference.
+ *
+ *  This driver module supports the following cards:
+ *      - SysKonnect TR4/16(+) PCI      (SK-4590)
+ *      - SysKonnect TR4/16 PCI         (SK-4591)
+ *      - Compaq TR 4/16 PCI
+ *      - Thomas-Conrad TC4048 4/16 PCI 
+ *      - 3Com 3C339 Token Link Velocity
+ *
+ *  Maintainer(s):
+ *    AF        Adam Fritzler
+ *
+ *  Modification History:
+ *      30-Dec-99       AF      Split off from the tms380tr driver.
+ *      22-Jan-00       AF      Updated to use indirect read/writes
+ *      23-Nov-00       JG      New PCI API, cleanups
+ *
+ *  TODO:
+ *      1. See if we can use MMIO instead of port accesses
