2 * INET An implementation of the TCP/IP protocol suite for the LINUX
3 * operating system. INET is implemented using the BSD Socket
4 * interface as the means of communication with the user level.
5 *
6 * Holds initial configuration information for devices.
7 *
8 * Version: @(#)Space.c 1.0.7 08/12/93
9 *
10 * Authors: Ross Biro, <bir7@leland.Stanford.Edu>
11 * Fred N. van Kempen, <waltje@uWalt.NL.Mugnet.ORG>
12 * Donald J. Becker, <becker@super.org>
13 *
14 * Changelog:
15 * Arnaldo Carvalho de Melo <acme@conectiva.com.br> - 09/1999
16 * - fix sbni: s/device/net_device/
17 * Paul Gortmaker (06/98):
18 * - sort probes in a sane way, make sure all (safe) probes
19 * get run once & failed autoprobes don't autoprobe again.
20 *
21 * FIXME:
22 * Phase out placeholder dev entries put in the linked list
23 * here in favour of drivers using init_etherdev(NULL, ...)
24 * combined with a single find_all_devs() function (for 2.3)
