/*
 * 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, <[e-mail]>
 *		Fred N. van Kempen, <[e-mail]>
 *		Donald J. Becker, <[e-mail]>
 *
 * Changelog:
 *		Paul Gortmaker (06/98): 
 *		 - sort probes in a sane way, make sure all (safe) probes
 *		   get run once & failed autoprobes don't autoprobe again.
 *
 *	FIXME:
 *		Phase out placeholder dev entries put in the linked list
 *		here in favour of drivers using init_etherdev(NULL, ...)
 *		combined with a single find_all_devs() function (for 2.3)
 *
