Those commits were not intended to fix any problems; just to make
the code and algorithm  more comprehensible. I doubt it will make any
difference.

When you have configured the zc706, can you confirm that it actually
has the correct address, and that the correct interface(s) is enabled?
If so, and everything is correct, you may have to instrument the code
and look at what is happening in the discovery logics (discover.c)
We can help you out with the latter, if you are positive that the configuraton
is ok, and the discovery broadcast actually don't go to the wrong interface.
