Kerry has merged fixes for the 2 sanity errors so you can synch your branch.

The proposed code changes look great. The structure is clean and efficient. The posted test results are all good.

I am posting a couple of comments. They are just questions, but at least one of them may require a minor change (in "merge" handling).

Thank you for making the incremental changes to address the issue regarding presence of the 'mac' option when creating a new IP neighbor.

All current proposed code changes and corresponding test results look good.

Approved.
