Subject: Not assigning a link local address by default breaks various things.
X-Git-Url: http://artulab.com/gitweb/?a=commitdiff_plain;h=bef794e1c7078038a0bef92153ce0d517b85779b;p=openbsd

Not assigning a link local address by default breaks various things.
A lot of code depends on a eui64 address to be present. So revert this
bit of the last commit.
