What about detecting that an ethernet link is flapping and in that
case it turns on link-quality measurement?

Because I think it is pretty uncommon for ethernet link to be coming
up and down. The main reason why Babel does not use link quality on
the ethernet link is that, arguably, failures on ethernet often means
a permanent failure and it is good to detect this quick. But if the
link is coming back soon afterwards and then again down and so on,
Babel should decide to instead go for packet loss? I think that would
be the best default.
