+dnl This test checks that repeated uses of a "learn" action cause the
+dnl modified time of the learned flow to advance. Otherwise, the
+dnl learned flow will expire after its hard timeout even though it's
+dnl supposed to be refreshed. (The expiration can be hard to see since
+dnl it gets re-learned again the next time a packet appears, but
+dnl sometimes the expiration can cause temporary flooding etc.)
