9508d2c4d7 * Added configurable default number of transmissions for CSMA to use when not specified using packetbuf attributes (CSMA_CONF_MAX_MAC_TRANSMISSIONS). 
* Renamed packetbuf attribute PACKETBUF_ATTR_MAX_MAC_REXMIT to PACKETBUF_ATTR_MAX_MAC_TRANSMISSIONS where value 0 (attribute not set) means that default number of transmissions should be used.

7bab9316da Two major changes: 
* Low-power streaming. Experimental support for a low-power mode which
  allows rapid exchange of packets with a 16% duty cycle. Does not
  seem to function correctly yet though.

* Phase locking. When the phase of a neighbor has been detected, the
  sender assumes that the neighbor will keeps it phase and does not
  send more strobes than necessary to hit the receiver's channel
  check - even if the receiver does not acknowledge the reception of
  the strobes when it should have been awake. Instead, the sender
  stops strobing and tries again at a later time.

7165a3866f Significant rework of the Contiki data collection protocol: 
* the new version makes use of MAC-layer feedback so that bad paths
  can be identified quicker and then avoided.

* the new code uses transport layer ACKs that contain feedback from
  the collect protocol: when a packet cannot be forwarded due to lack
  of resources, the ACK contains a flag that indicates that the packet
  could not be forwarded. ACKs also contain the routing metric of the
  sender, which improves agility in face of rapid path changes.

* loop detection and management has been improved: with higher path
  metric agility, the system is more prone to short-lived routing
  loops. Instead of dropping looping packets, the new version adjusts
  the routing metric for the routes that exhibit loops so that the
  risk for future loops is reduced.

* make use of packet attributes to inform the MAC layer of how many
  times packets should be retransmitted.
