What will happen if you use fisheye?

Was the bug fix so that olsr will not start a duplicate or so that it
would not propagate it? I assume only to not start it because I see the
propagation?

It is happening again. This time I see two duplicated hna messages.
Currently the only way I can get rid of these is by blocking olsr packets
from the originator address.

Would it be a mission to add code to filter duplicates? Is there a use
for duplicate messages? Up to now I have only seen hna duplicate messages.
Would there be a reason for it? I guess the place to start is hna_set.c?

Thanks
