Author: qingli Date: Wed Aug 12 19:15:26 2009 New Revision: 196152 URL: http://svn.freebsd.org/changeset/base/196152 Log: A piece of code was added to install a host route when an IPv6 interface address is configured with a /128 prefix. This is no longer necessary due to r192011. In fact that code conflicts with r192011. This patch removes the host route installation when detecting the /128 prefix, and instead let the code added by r192011 to install the loopback route for that IPv6 interface address.
