1 /* 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 11 * Fred N. van Kempen, <waltje@uWalt.NL.Mugnet.ORG> 12 * Donald J. Becker, <becker@scyld.com> 13 * 14 * Changelog: 15 * Stephen Hemminger (09/2003) 16 * - get rid of pre-linked dev list, dynamic device allocation 17 * Paul Gortmaker (03/2002) 18 * - struct init cleanup, enable multiple ISA autoprobes. 19 * Arnaldo Carvalho de Melo <acme@conectiva.com.br> - 09/1999 20 * - fix sbni: s/device/net_device/ 21 * Paul Gortmaker (06/98): 22 * - sort probes in a sane way, make sure all (safe) probes 23 * get run once & failed autoprobes don't autoprobe again. 24 * 25 * This program is free software; you can redistribute it and/or 26 * modify it under the terms of the GNU General Public License 27 * as published by the Free Software Foundation; either version 28 * 2 of the License, or (at your option) any later version. 29 */ 30 #include <linux/netdevice.h> 31 #include <linux/etherdevice.h> 32 #include <linux/trdevice.h> 33 #include <linux/errno.h> 34 #include <linux/init.h> 35 #include <linux/netlink.h> 36 37 /* A unified ethernet device probe.
