That's interesting. Could I please see a log?

Interesting. AFAIK, ECN is only considered by AQM queues, so this implies
there's a queue in the way that's dropping Babel packets. Perhaps this
queue could be convinced to treat Babel packets specially without having
to hack around it using ECN? Or perhaps, if we know which queue that is,
we could modify Babel's packet scheduling to be more AQM friendly?
