- * smctr.c: A network driver for the SMC Token Ring Adapters.
- *
- * Written by Jay Schulist <jschlst@samba.org>
- *
- * This software may be used and distributed according to the terms
- * of the GNU General Public License, incorporated herein by reference.
- *
- * This device driver works with the following SMC adapters:
- * - SMC TokenCard Elite (8115T, chips 825/584)
- * - SMC TokenCard Elite/A MCA (8115T/A, chips 825/594)
- *
- * Source(s):
- * - SMC TokenCard SDK.
- *
- * Maintainer(s):
- * JS Jay Schulist <jschlst@samba.org>
- *
- * Changes:
- * 07102000 JS Fixed a timing problem in smctr_wait_cmd();
- * Also added a bit more discriptive error msgs.
- * 07122000 JS Fixed problem with detecting a card with
- * module io/irq/mem specified.
- *
- * To do:
- * 1. Multicast support.
- *
- * Initial 2.5 cleanup Alan Cox <alan@lxorguk.ukuu.org.uk> 2002/10/28
