Hello Brian,

The option could be simpler, because its only purpose would
be to distinguish different flooded packets.  Since any node
adding this option would use the same hash to find if there
had been a collision recently, there would be no need for the
Tagger ID.  I reckon that the data field for the option might
only have to be one byte, but of course there is all the glue.

Regards,
Charlie P.
