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...
