26 * \brief Less trivial test of OLSR Topology Control message generation
27 *
28 * This test simulates 3 Wi-Fi stations with chain topology and runs OLSR without any extra traffic.
29 * It is expected that only second station will send TC messages.
30 *
31 * Expected trace (20 seconds, note random b-cast jitter):
