+ *  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@redhat.com>  2002/10/28
