OK I finally got this to work, however, I cannot boot to single user,
and then 'exit' to mutli-user and have it work.  I'm not sure what's
broken there.

Also, I'm still having a problem with 'tentative'.   For example I
assigned the internal interface with my prefix manually:

ifconfig internal inet6 [prefix]/64 eui64

'tentative' is supposed to disappear after DAD, but instead 'hangs on'
indefinitely.  There appears to be a bug there.  There is no collision
unless it's seeing it's own broadcast somehow.  Even if it did, there's
no log/complaining.

If I set dad count to 0 and remove and re-add the address, still stuck.
