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.
