Linux-2.6.12-rc2
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!

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