e000b1abf3 A major update to ContikiRPL resulting in a reduced code footprint by
300 bytes, as well as cleaner protocol logic.

* Made parent management uniform.

* Simplified the DIO processing.

* Improved the Objective Function API and its documentation.

* Removed redundant code at various places.

* Improved identifier naming.

* Switched visualization from candidate parents to preferred parents only.

* Made DAO ACK transmissions configurable.

* Improved initial ETX guess by using a cached local confidence value.

* Added a periodical rank recalculation function to reduce
  the maximum stack depth.

* Increased the Trickle redundancy constant to ensure faster
  topological updates.

c201058325 Purge all routes related to a DAG being freed. Do not send no-DAOs when doing a global repair. 2010-06-03 15:20:56 +00:00

f135105567 Added support for multiple objective functions.
Extended the objective function API with a callback function that receives link-layer neighbor information.

Throttled DAO transmissions to one per DEFAULT_DAO_LATENCY period.

Added support for an ETX objective function (hysteresis control still lacking though).

Fixed a leak of routes installed by DAOs.

Control that dst_adv_supported is set before sending DAOs.

Improved debugging output.
