/*
* 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...
