 * 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 
 * NOTE:        This file is a nice idea, but its current format does not work
9 
 *              well for drivers that support multiple units, like the SLIP
10 
 *              driver.  We should actually have only one pointer to a driver
11 
 *              here, with the driver knowing how many units it supports.
12 
 *              Currently, the SLIP driver abuses the "base_addr" integer
13 
 *              field of the 'device' structure to store the unit number...
