| * 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... |
