/*
 * 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
 * File successfully sent (1116 bytes)
 * Reply: ok
