2 * 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...
