/*
* 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.
