[Olsr-dev] olsrd etx + plugin

Thank you Henning. That's a good way to go about doing this. However, the
version of olsr installed on my devices is 0.5.5. I would like to keep them
on that version for now. Is updating them to the most recent development
version (for using your lq-Plugin suggestion) the only way for now?

The only thing you need is a modified lq-Plugin (see /lib/lq_... for
examples). The whole link quality calculation of the development-tip of
olsr.org is concentrated in this plugins.

And you will find an experimental OLSR version that can read transmission
speed of WLAN cards into an internal database here (needs kernel 2.6.29):
