c3f62b24c8 Moved ETX management from neighbor-info to rpl-of-etx. Avoids conversions between different fixed point representations, and simplifies neighbor management. Makes more clear how default-ETX and noack-ETX actually affect the rank. Removed neighbor-info and neighbor-attr. 2013-08-19 17:48:30 +02:00

512a339c50 Bugfix: DIOs with infinite ranks should not be ignored as they are used by RPL as a signal by nodes that have lost their routes. Instead of ignoring them, we should send out our latest information to let the node with infinite rank find their way into the network again. 2013-07-26 12:38:25 +02:00

afe13b22bc Rewrote the uIP IPv6 route handling code. Instead of being nested deeply inside the uip-ds6.c file, the route management code is now in a separate file, uip-ds6-route.c. This file presents a lib/list.h API for the routes, which makes the route list much easier to use. Additionally, the uip-ds6-route.c file adds a callback API that invokes a callback when routes are added and removed. 2012-11-27 23:04:33 +01:00

15deb37e64 Updated DAG version processing to occur even for infinite rank DIOs. This makes it possible for the RPL root to infer the DAG version number from a network that hasn't had a root for a while, and where the rank has increased to infinity. 2012-11-27 23:04:30 +01:00
