/*
 * 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.
