/*
 * 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, <[email protected]>
 *      Donald J. Becker, <[email protected]>
 *
 * 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 <[email protected]> - 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.
