* 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.

|
|
* 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...
