- * jazzsonic.c
- *
- * (C) 2005 Finn Thain
- *
- * Converted to DMA API, and (from the mac68k project) introduced
- * dhd's support for 16-bit cards.
- *
- * (C) 1996,1998 by Thomas Bogendoerfer (tsbogend@alpha.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 onboard Sonic ethernet controller on Mips Jazz
- * systems (Acer Pica-61, Mips Magnum 4000, Olivetti M700 and
- * perhaps others, too)
