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.
