Comments would sometimes be so helpful to better understand what is
supposed to happen.  Let's just add one.
A couple of sample shell scripts to manage the LPM table for tests

It is a great learning experience and a great time sink at the end
of the week.

Still "abusing" the OSPF counter for state debugging on real hw,
just in case the bitfile might do anything.
