that the mirroring action is triggered by a flower match.

+# This tests flower-triggered mirroring to gretap and ip6gretap netdevices. The
+# interfaces on H1 and H2 have two addresses each. Flower match on one of the
+# addresses is configured with mirror action. It is expected that when pinging
+# this address, mirroring takes place, whereas when pinging the other one,
+# there's no mirroring.
