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.
