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