node" is bad, but using LinkQualityMult to say "please do not use my
node/interface if it is not really necessary" is something else. And
currently LinkQualityMult is not good even for this as it sets LQ only

link which is otherwise lossless. That is why I would like to see
something more like "willingness" I have described. Which would
influence end ETX value not all (real) values calculated by different

currently there is no nice way to flag your own node/interface as
