/*

 * 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.
