/*
 * 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...
