* 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
