      4 # This test uses standard topology for testing gretap. See
      5 # mirror_gre_topo_lib.sh for more details.
      6 #
      7 # This tests flower-triggered mirroring to gretap and ip6gretap netdevices. The
      8 # interfaces on H1 and H2 have two addresses each. Flower match on one of the
      9 # addresses is configured with mirror action. It is expected that when pinging
     10 # this address, mirroring takes place, whereas when pinging the other one,
     11 # there's no mirroring.
