-/*
- * abyss.c: Network driver for the Madge Smart 16/4 PCI Mk2 token ring card.
- *
- * Written 1999-2000 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:
- * - Madge Smart 16/4 PCI Mk2
- *
- * 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 inb/outb/inw/outw
- * 2. Add support for Mk1 (has AT24 attached to the PCI
- * config registers)
- *
