Detailed Description

Less trivial test of OLSR Topology Control message generation.

This test simulates 3 Wi-Fi stations with chain topology and runs OLSR without any extra traffic. It is expected that only second station will send TC messages.

Expected trace (20 seconds, note random b-cast jitter):
