typedef union uip_ip4addr_t {
u16_t u16[2];
u8_t u8[4];
} uip_ip4addr_t;
typedef uip_ip4addr_t uip_ipaddr_t;
This implies that one must consistently pass pointers to
uip_ipaddr_t:s and not mix and match pointers with
uip_ipaddr_t:s as was done earlier.

/*

|
* 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
