Perform the path between a node and the DAG root in respect with the RPL algorithm.
[R] = NL_R_RPLPath(S,D,P)
RPL root.
Destination node.
Predecessor vector.
Path.
NL_R_RPLPath performs the path R between the node D and the DAG root S in respect with the RPL algorithm. The predecessor vector P is generated by the RPL algorithm started from the root S.
