5 *
6 * This software may be used and distributed according to the terms
7 * of the GNU General Public License, incorporated herein by reference.
8 *
9 * This device driver works with the following SMC adapters:
10 * - SMC TokenCard Elite (8115T, chips 825/584)
11 * - SMC TokenCard Elite/A MCA (8115T/A, chips 825/594)
12 *
13 * Source(s):
14 * - SMC TokenCard SDK.
15 *
16 * Maintainer(s):
17 * JS Jay Schulist <jschlst@samba.org>
18 *
19 * Changes:
20 * 07102000 JS Fixed a timing problem in smctr_wait_cmd();
21 * Also added a bit more discriptive error msgs.
22 * 07122000 JS Fixed problem with detecting a card with
23 * module io/irq/mem specified.
24 *
25 * To do:
26 * 1. Multicast support.
27 *
28 * Initial 2.5 cleanup Alan Cox <alan@redhat.com> 2002/10/28
