Finally, after some more discussions, observations and better
overall understanding of the issue we were able to find a
successful strategy for ARP reduction.

The result is an additional patch which introduces a generic
"noflood mark" which for ARP Requests means a prevention of
the DAT broadcast fallback.

At Freifunk Darmstadt, an 800 nodes setup, these two patches
were tested for a month with no issues so far but a significant
amount of ARP Request reduction.
