selftests: forwarding: Test flower mirror to gretap
Add a test for mirroring to a gretap and an ip6gretap netdevices such that the mirroring action is triggered by a flower match. Signed-off-by: Petr Machata <petrm@mellanox.com> Reviewed-by: Jiri Pirko <jiri@mellanox.com> Signed-off-by: David S. Miller <davem@davemloft.net>

+#
+# 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.
