Neighbor ETX should accumulate over retransmission timeouts;
...
Best neighbor has minimum sum of routing metric and neighbor ETX. Previously best neighbor prioritizes routing metric before neighbor ETX, which often causes a poor neighbor with a good upstream path to be selected.

Added logic for announcing that a network has a gateway to the outside world (with the function uip_over_mesh_make_announced_gateway()). The announced gateway sends a trickle message to the network, containing the address of the gateway. Other nodes will then know that packets destined to the outside world should go through the gateway node.

Bugfix: there was a problem with TCP segments not being properly retransmitted for protosockets-based applications. Cleaning up the logic around acknowledgements and retransmissions fixed the bugs pertaining to retransmissions of lost packets. This bugfix affects both the telnet server and the web server (which now work as expected wrt packet loss).

This is an initial commit of an implementation of the Chameleon
...
architecture for the Rime stack for Contiki. The Chameleon
architecture separates the header processing from the Rime protocol
logic. Instead of having each protocol create its own part of the
packet header, protocols use packet attributes. Before sending a
packet, a special Chameleon header processing module creates a packet
header from the packet attributes. The same Chameleon module parses
incoming packets and creates packet attributes from the header.
