 * change all splnet's to splimp's
 *
 * Revision 2.13  1993/11/22  10:53:52  davidg
 * patch to add support for SMC8216 (Elite-Ultra) boards
 * from Glen H. Lowe
 *
 * Revision 2.12  1993/11/07  18:04:13  davidg
 * fix from Garrett Wollman:
 * add a return(0) at the end of ed_probe so that if the various device
 * specific probes fail that we just don't fall of the end of the function.
