LT		 1/*
2 * macsonic.c
3 *
efcce839
FT		 4 * (C) 2005 Finn Thain
5 *
6 * Converted to DMA API, converted to unified driver model, made it work as
7 * a module again, and from the mac68k project, introduced more 32-bit cards
8 * and dhd's support for 16-bit cards.
9 *
1da177e4
LT		 10 * (C) 1998 Alan Cox
11 *
12 * Debugging Andreas Ehliar, Michael Schmitz
13 *
14 * Based on code
15 * (C) 1996 by Thomas Bogendoerfer (tsbogend@bigbug.franken.de)
6aa20a22 16 *
1da177e4
LT		 17 * This driver is based on work from Andreas Busse, but most of
18 * the code is rewritten.
6aa20a22 19 *
1da177e4
LT		 20 * (C) 1995 by Andreas Busse (andy@waldorf-gmbh.de)
21 *
22 * A driver for the Mac onboard Sonic ethernet chip.
23 *
6aa20a22 24 * 98/12/21 MSch: judged from tests on Q800, it's basically working,
1da177e4
LT		 25 * but eating up both receive and transmit resources
26 * and duplicating packets. Needs more testing.
27 *
28 * 99/01/03 MSch: upgraded to version 0.92 of the core driver, fixed.
6aa20a22 29 *
1da177e4
LT		 30 * 00/10/31 sammy@oh.verio.com: Updated driver for 2.4 kernels, fixed problems
31 * on centris.
