2 | * macsonic.c | |

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 | * | |

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) | |
16 | * | |
17 | * This driver is based on work from Andreas Busse, but most of | |
18 | * the code is rewritten. | |
19 | * | |
20 | * (C) 1995 by Andreas Busse (andy@waldorf-gmbh.de) | |
21 | * | |
22 | * A driver for the Mac onboard Sonic ethernet chip. | |
23 | * | |
24 | * 98/12/21 MSch: judged from tests on Q800, it's basically working, | |
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. | |
29 | * | |
30 | * 00/10/31 sammy@oh.verio.com: Updated driver for 2.4 kernels, fixed problems | |
31 | * on centris. | |
