2 * INET		An implementation of the TCP/IP protocol suite for the LINUX
3 *		operating system.  INET is implemented using the  BSD Socket
4 *		interface as the means of communication with the user level.
5 *
6 *		Holds initial configuration information for devices.
7 *
8 * Version:	@(#)Space.c	1.0.7	08/12/93
9 *
10 * Authors:	Ross Biro
11 *		Fred N. van Kempen, <waltje@uWalt.NL.Mugnet.ORG>
12 *		Donald J. Becker, <becker@scyld.com>
13 *
14 * Changelog:
15 *		Stephen Hemminger (09/2003)
16 *		- get rid of pre-linked dev list, dynamic device allocation
17 *		Paul Gortmaker (03/2002)
18 *		- struct init cleanup, enable multiple ISA autoprobes.
19 *		Arnaldo Carvalho de Melo <acme@conectiva.com.br> - 09/1999
20 *		- fix sbni: s/device/net_device/
21 *		Paul Gortmaker (06/98):
22 *		 - sort probes in a sane way, make sure all (safe) probes
23 *		   get run once & failed autoprobes don't autoprobe again.
