/*
|

* Example gateway configuration with two IP interfaces, one SLIP over
|
||||
* USB and one over 802.11.4 radio.
|
||||
*
|
||||
* The IP address is hardcoded to 172.16.0.1 and the 172.16/16 network
|
||||
* is on the radio interface.
|
||||
*
|
||||
* The default route is over the SLIP interface.
|
||||
*
|
||||
* On the SLIP host run a standard SLIP implementation or the tunslip
|
||||
* program that can also view debug printfs, example:
|
||||
*
|
||||
* sliphost# ./tunslip 172.16.0.1 255.255.0.0
|
||||
*
|
||||
*
|
||||
* This kernel has no application code but new modules can be uploaded
|
||||
* using the codeprop program, example:
|
||||
*
|
||||
* datan$ ./codeprop 172.16.0.1 loadable_prg.ko
