Here it is. The differences of "route get" between -current kernel and the new implementation are: - Flag CLONING is changed to CONNECTED. - If a nexthop entry is cached, "route get" to it was changed from a cloning route to a cloned route (nexthop entry) while the new implementation always shows a connected route. During collecting the outputs, I found a bug route get <nexthop> was broken. So I fixed it: http://www.netbsd.org/~ozaki-r/separate-nexthop-caches-v4.diff http://www.netbsd.org/~ozaki-r/separate-nexthop-caches-v4-diff.diff In order to fix the issue, I needed a workaround to keep backward compatibility (for old binaries of arp/ndp -d). See the comment of the 2nd patch for details.
