/*
* 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, <bir7@leland.Stanford.Edu>
* Fred N. van Kempen, <waltje@uWalt.NL.Mugnet.ORG>
* Donald J. Becker, <becker@scyld.com>
*
* Changelog:
* 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.
*
* FIXME:
* Phase out placeholder dev entries put in the linked list
* here in favour of drivers using init_etherdev(NULL, ...)
* combined with a single find_all_devs() function (for 2.3)
