   2  * macsonic.c
   3  *
   4  * (C) 1998 Alan Cox
   5  *
   6  * Debugging Andreas Ehliar, Michael Schmitz
   7  *
   8  * Based on code
   9  * (C) 1996 by Thomas Bogendoerfer (tsbogend@bigbug.franken.de)
  10  *
  11  * This driver is based on work from Andreas Busse, but most of
  12  * the code is rewritten.
  13  *
  14  * (C) 1995 by Andreas Busse (andy@waldorf-gmbh.de)
  15  *
  16  * A driver for the Mac onboard Sonic ethernet chip.
  17  *
  18  * 98/12/21 MSch: judged from tests on Q800, it's basically working,
  19  *                but eating up both receive and transmit resources
  20  *                and duplicating packets. Needs more testing.
  21  *
  22  * 99/01/03 MSch: upgraded to version 0.92 of the core driver, fixed.
  23  *
  24  * 00/10/31 sammy@oh.verio.com: Updated driver for 2.4 kernels, fixed problems
  25  *          on centris.
