+ * INET                An implementation of the TCP/IP protocol suite for the LINUX
+ *             operating system.  INET is implemented using the  BSD Socket
+ *             interface as the means of communication with the user level.
+ *
+ *             Holds initial configuration information for devices.
+ *
+ * Version:    @(#)Space.c     1.0.7   08/12/93
+ *
+ * Authors:    Ross Biro
+ *             Fred N. van Kempen, <waltje@uWalt.NL.Mugnet.ORG>
+ *             Donald J. Becker, <becker@scyld.com>
+ *
+ * Changelog:
+ *             Stephen Hemminger (09/2003)
+ *             - get rid of pre-linked dev list, dynamic device allocation
+ *             Paul Gortmaker (03/2002)
+ *             - struct init cleanup, enable multiple ISA autoprobes.
+ *             Arnaldo Carvalho de Melo <acme@conectiva.com.br> - 09/1999
+ *             - fix sbni: s/device/net_device/
+ *             Paul Gortmaker (06/98):
+ *              - sort probes in a sane way, make sure all (safe) probes
+ *                get run once & failed autoprobes don't autoprobe again.
