as I wrote, if you want to use specific interface id (lower 64 bits)
you can swap link-local address. I don't recommend it since
we did not make extensive tests for it.

If you want the following:
- For servers
- put name-address mapping onto DNS
- and would like to use the mapping across ethernet card replacement
it is covered.
You should be okay if you configure extra address.
# ifconfig ne2 inet6 3ffe:501:ffff::1 prefixlen 64 alias
and put it onto DNS.
myserver.flame.org. IN AAAA 3ffe:501:ffff::1
You do not need to worry about extra addresses configured from
MAC-address based link-locals. If you don't advertisem them in
DNS, they won't be used by clients. When you initiate a connection
from the server, it may occasionally be used.
