0007 # This tests flower-triggered mirroring to gretap and ip6gretap netdevices. The
0008 # interfaces on H1 and H2 have two addresses each. Flower match on one of the
0009 # addresses is configured with mirror action. It is expected that when pinging
0010 # this address, mirroring takes place, whereas when pinging the other one,
0011 # there's no mirroring.
