I could narrow down the problem to the fact that no TC messages are by
olsrd2 daemon. I am using OpenWRT with "oonf-olsrd2 - 0.9.2" installed.

I tried changing tc_interval to e.g. 3.0 but this did not changed anything.

Any idea how I should further debug the problem? Which part of the code
decides whether to send TC messages or not?
