From 5c2dae8edc8ba97935136bd4cea593c2e64f6f8f Mon Sep 17 00:00:00 2001
From: Garrett Wollman <wollman@FreeBSD.org>
Date: Wed, 2 Nov 1994 04:41:39 +0000
Subject: Add code to be a bit smarter about IP routes, conditioned on the
 option IN_RMX.  (Eventually this will be standard, but I just wrote the code
 today and don't want to break anyone.)
