Hello everyone, I need to access the "prev_hop_" filed of the data packets, in order to update some protocol states in my program.
I am using the OLSR routing agent. And I have already checked the recv() and forward_data() functions, there is no sign that the 'prev_hop_' field is set or modified as I wanted. could anybody tell me if the 'prev_hop_' field is automatically changed somewhere else, like in the mac layer? or should I set and modify it every time I send a packet? Any help would be appreciated, thanks in advance. Edward Lee.
