Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

2 * tmspci.c: A generic network driver for TMS380-based PCI token ring cards.
3 *
4 * Written 1999 by Adam Fritzler
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 driver module supports the following cards:
10 * - SysKonnect TR4/16(+) PCI (SK-4590)
11 * - SysKonnect TR4/16 PCI (SK-4591)
12 * - Compaq TR 4/16 PCI
13 * - Thomas-Conrad TC4048 4/16 PCI
14 * - 3Com 3C339 Token Link Velocity
15 *
16 * Maintainer(s):
17 * AF Adam Fritzler mid@auk.cx
18 *
19 * Modification History:
20 * 30-Dec-99 AF Split off from the tms380tr driver.
21 * 22-Jan-00 AF Updated to use indirect read/writes
22 * 23-Nov-00 JG New PCI API, cleanups
23 *
24 * TODO:
25 * 1. See if we can use MMIO instead of port accesses
26 *
