   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.
