   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.
