  1. /*
  2. * macsonic.c
  3. *
  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.
