After further thought the chicken or egg issue does not exist as all
IPV6 devices come up with an auto created link-local address which would
be used to query dhcp where it can be given another static link-local
address. The only way it would exist is if the device did not do a query
to see if a dhcp server is trying to give it an additional address.
