Subject: There is a problem with assigning 127.0.0.1 here. Revert the call
X-Git-Url: http://artulab.com/gitweb/?a=commitdiff_plain;h=c539b04c9400aacaff594a8bb3daf9bd02452111;p=openbsd

There is a problem with assigning 127.0.0.1 here. Revert the call
to in_up_loopback(). There is an issue when doing ifconfig lo0 127.0.0.1/8
the system ends up with 2 127.0.0.1 routes which breaks things like smptd.
