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!

+ * macsonic.c
+ *
+ * (C) 1998 Alan Cox
+ *
+ * Debugging Andreas Ehliar, Michael Schmitz
+ *
+ * Based on code
+ * (C) 1996 by Thomas Bogendoerfer (tsbogend@bigbug.franken.de)
+ *
+ * This driver is based on work from Andreas Busse, but most of
+ * the code is rewritten.
+ *
+ * (C) 1995 by Andreas Busse (andy@waldorf-gmbh.de)
+ *
+ * A driver for the Mac onboard Sonic ethernet chip.
+ *
+ * 98/12/21 MSch: judged from tests on Q800, it's basically working,
+ * but eating up both receive and transmit resources
+ * and duplicating packets. Needs more testing.
+ *
+ * 99/01/03 MSch: upgraded to version 0.92 of the core driver, fixed.
+ *
+ * 00/10/31 sammy@oh.verio.com: Updated driver for 2.4 kernels, fixed problems
+ * on centris.
