Joakim Eriksson 09c624dcd3 fixed clearing of state flag and avoid starting retransmission timer 2016-03-26 09:45:38 +01:00
Joakim Eriksson 8afe3fb9b7 fixed so that DAO NACK now is either for the path or for RPL root - if from root then do not try to switch parent since that will not help 2016-03-26 09:45:38 +01:00
Joakim Eriksson 13b8c04c6f fixed so that nbr policy for RPL Root do not save room for parents 2016-03-26 09:45:38 +01:00
Joakim Eriksson 1fcef0f90d added function for checking downward route and added configuration for DAO NACK repair - default off 2016-03-26 09:45:38 +01:00
Joakim Eriksson 444015df67 refactored the rpl-nbr-policy to be called from nbr-table module 2016-03-26 09:45:37 +01:00
Joakim Eriksson be81d1d2c6 added uip_clear_buf to avoid the risk of sending received packets 2016-03-26 09:45:37 +01:00
Joakim Eriksson fa1b70b723 added configuration of DAO route refresh for broadcast DIOs 2016-03-26 09:45:36 +01:00
Joakim Eriksson 3fd8c4db2d added nbr policy for Contiki RPL that avoids thrashing the nbr table with new entries all the time 2016-03-26 09:45:36 +01:00
Joakim Eriksson 946be77248 Added support for end-to-end DAO ACK for Contiki RPL.
This is a fix for Contiki RPL so that it fully supports DAO ACK in
an end-to-end fashion. When DAO is sent it will be forwarded upwards
as before. DAO ACK will be forwarded downwards until it reach the node
that initiated the DAO ACK and unlike before it is not a single-hop
DAO ACK but it is fully reaching the RPL ROOT before any DAO ACK is
sent back. DAO ACK also now fully support different status messages
(success / fail).

Valentin Sawadski b0c7dabf4c Removes duplicate of uip_is_addr_linklocal
A simple search and replace of `uip_is_addr_link_local` to ensure the more
commonly used `uip_is_addr_linklocal` is used consistently.

Adam Dunkels faff1c2a7e Preliminary support for RPL node types. This change allows a node to be in any of three given types:
* Mesh: this is the normal case. Nodes route data on behalf of others and the node can be reached via a DAO route.
* Leaf: the node does not route data on behalf of others, but others can route data to the node (it has a RPL DAO route).
* Feather: this is a new type of node. A feather node routes data on behalf of others, but does not install DAO routes in the network. Feather nodes allow having a larger number of nodes than the RPL network can sustain in terms of routing tables.

This commit introduces the RPL node types and the feather mode, but does not add support for the leaf node type.
