Looks good to me.

One question thought.  What causes the stack to send via Default Router instead
of sending an NS (Section 3.2).  I see there is code to prevent sending NS from
the optimistic address, but I see nothing that would send this packet to a default
router.  This might be buried somewhere in the routing code, but I just can't see it.

Thanks
