/*
 * Example configuration with one statically configured IP interface.
 *
 * The IP address is hardcoded to 172.16.0.9 and the 172.16/16 network
 * is on the radio interface.
 *
 * The default route and gateway is at 172.16.0.1.
 *
 * On the SLIP gateway 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 172.16.0.9 loadable_prg.ko
 * File successfully sent (1116 bytes)
 * Reply: ok
