Hello, Doug.

man ifconfig has only one mention about link-local addresses in BUGS
section (with warning about removing them by hands) and mention, that
they are automagically assigned on interface creation, if
net.inet6.ip6.auto_linklocal is set to 1 (which is true on my system,
but all my interfaces were created BEFORE IPv6 has been enabled in
system).
/etc/rc.d/auto_linklocal works only with lo0.
It seems to me, that it is impossible to force kernel to create
link-local addresses for already-created interfaces. But I want to be
wrong here!
