+ * 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.
