* Revision 2.2 93/09/29 13:23:25 davidg

 * added no multi-buffer override for 3c503
 *
 * Revision 2.1  93/09/29  12:32:12  davidg
 * changed multi-buffer count for 16bit 3c503's from 5 to 2 after
 * noticing that the transmitter becomes idle because of so many
 * packets to load.
 *
 * Revision 2.0  93/09/29  00:00:19  davidg
 * many changes, rewrites, additions, etc. Now supports the
 * NE1000, NE2000, WD8003, WD8013, 3C503, 16bit 3C503, and
 * a variety of similar clones. 16bit 3c503 now does multi
 * transmit buffers. Nearly every part of the driver has
 * changed in some way since rev 1.30.
