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 | * | |
02c30a84 | 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/ | |
6aa20a22 | 21 | * Paul Gortmaker (06/98): |
1da177e4 LT |
22 | * - sort probes in a sane way, make sure all (safe) probes |
23 | * get run once & failed autoprobes don't autoprobe again. | |
