Keep track of STA journeys between multiple nodes. When a new STA is reported from a foreign node, check whether this STA was previously associated with a local node. Vice versa, check upon association whether or not the STA was previously associated with a foreign node. Keep track of these roaming transactions using two new (local) fields of the node struct.
