Release 4.7 drivers/net/Space.c

/*
 * INET         An implementation of the TCP/IP protocol suite for the LINUX
 *              operating system.  INET is implemented using the  BSD Socket
 *              interface as the means of communication with the user level.
 *
 *              Holds initial configuration information for devices.
 *
 * Version:     @(#)Space.c     1.0.7   08/12/93
 *
 * Authors:     Ross Biro
 *              Fred N. van Kempen, <waltje@uWalt.NL.Mugnet.ORG>
 *              Donald J. Becker, <becker@scyld.com>
 *
 * Changelog:
 *              Stephen Hemminger (09/2003)
 *              - get rid of pre-linked dev list, dynamic device allocation
 *              Paul Gortmaker (03/2002)
 *              - struct init cleanup, enable multiple ISA autoprobes.
 *              Arnaldo Carvalho de Melo <acme@conectiva.com.br> - 09/1999
 *              - fix sbni: s/device/net_device/
 *              Paul Gortmaker (06/98):
 *               - sort probes in a sane way, make sure all (safe) probes
 *                 get run once & failed autoprobes don't autoprobe again.
