17 * - get rid of pre-linked dev list, dynamic device allocation
18 * Paul Gortmaker (03/2002)
19 * - struct init cleanup, enable multiple ISA autoprobes.
20 * Arnaldo Carvalho de Melo <acme@conectiva.com.br> - 09/1999
21 * - fix sbni: s/device/net_device/
22 * Paul Gortmaker (06/98):
23 * - sort probes in a sane way, make sure all (safe) probes
24 * get run once & failed autoprobes don't autoprobe again.
