I don't mean to speak for Tariq (so my apologies Tariq), but I
suspect it may not be clear in which cases IFF_UP is checked and in
which cases get_base is called.

I tried to clear it up in my longer response with examples from

If you have a moment could you take a look and let me know if I've
gotten it wrong in my explanation/walk through?
