-/*
- * skisa.c: A network driver for SK-NET TMS380-based ISA token ring cards.
- *
- * Based on tmspci written 1999 by Adam Fritzler
- *
- * Written 2000 by Jochen Friedrich
- * Dedicated to my girlfriend Steffi Bopp
- *
- * 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(+) ISA (SK-4190)
- *
- * Maintainer(s):
- * AF Adam Fritzler
- * JF Jochen Friedrich jochen@scram.de
- *
- * Modification History:
- * 14-Jan-01 JF Created
- * 28-Oct-02 JF Fixed probe of card for static compilation.
- * Fixed module init to not make hotplug go wild.
- * 09-Nov-02 JF Fixed early bail out on out of memory
- * situations if multiple cards are found.
- * Cleaned up some unnecessary console SPAM.
- * 09-Dec-02 JF Fixed module reference counting.
- * 02-Jan-03 JF Renamed to skisa.c
- *
