batman-adv has no ability to manually manipulate the cost of a link. Our goal 
is to make batman-adv as easy to use as possible, thus we refrain from adding 
too many configuration options. We'd rather implement an automatic detection 
even if it comes at the cost of not being amongst the first of supporting a 
certain feature.
