/* * 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. * * NOTE: This file is a nice idea, but its current format does not work * well for drivers that support multiple units, like the SLIP * driver. We should actually have only one pointer to a driver * here, with the driver knowing how many units it supports. * Currently, the SLIP driver abuses the "base_addr" integer * field of the 'device' structure to store the unit number... * -FvK * * Version: @(#)Space.c 1.0.7 08/12/93 * * Authors: Ross Biro, * Fred N. van Kempen, * Donald J.
