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, <[email protected]>
12  * Donald J. Becker, <[email protected]>
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 <[email protected]> - 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.
