[Olsr-dev] LinkQualityMult support for olsrd development branch

[David Murray]

Hi Henning,

Tried it again this afternoon, default routes seemed to work fine. I'm 
not sure why they were not working before. Also, the rewrite of ETX 
seemed to work fine with nodes running the old version (olsrd5.5). I 
only had time to test it out on 3 dual radio nodes this afternoon.

I am still noticing that the rewrite of the ETX metric is giving 
different/higher costs. Do you know why this might be occurring? I 
would have thought that they should give the same cost if they are both 
based on [1].

Tomorrow morning I will load it onto the other three nodes and let you 
know how I go.

Regards,
Dave
