If my 10Ge has 5% packet loss, its broken. I don't want to use
it. Falling back to the 56K link is the right thing to do.

There is a general rule of thumb. The higher the bandwidth, the less
packet loss there is. This is because high bandwidth links are
generally not wireless and so don't suffer high packet loss.

As a side effect, BATMAN will tend to favor wired links over wireless
links, because wired links tend to be reliable, wireless links drop
