 2007-05-21 14:30:38 +00:00
bg- 1009c3fabf * Literal constants REMOTE_*. 2007-05-21 14:24:51 +00:00
bg- be3d5e8394 * s/uip-fw-service/uip-fw-drv/ 2007-05-21 14:13:04 +00:00
oliverschmidt 5f3296e943 Changed packet drivers from services to plain processes. 
Now tcpip_output() is a function pointer that is supposed to be set via the macro tcpip_set_outputfunc(). Packet drivers do so on process startup.

Thus if there are several packet drivers in a Contiki system the one started last is the one actually used. This behaviour is especially useful for the 'IP forwarding' "meta" packet driver.

fros4943 42a952981b bugfix: could not store last seen rreqs 2007-05-20 20:08:28 +00:00
oliverschmidt c32b2ca581 Replaced function with macro. 2007-05-20 00:04:18 +00:00
oliverschmidt 9f97290665 Changed Contiki File System (cfs) from a service to a plain library. 
This change means that one needs to select _ONE_ cfs implementation at Contiki library link time. But this doesn't appear to be an issue as all platforms have their "favorite" implementation anyway.

bg- faf94db265 * Respect "destination only" flag in RREQs.

this using conditional compilation (AODV_COMPLIANCE).

bg- 8b1cd7a470 * Explain that SCMP32 comes from RFC 3561 and is easy to implement 
using 2's complement arithmetic. Unfortunately C only defines
  unsigned arithmetic and consequently machines that don't use 2's
  complement (i.e unknown arithmetic) will have to be dealt with on a
  per machine basis.
