| # This test uses standard topology for testing gretap. See |
| # mirror_gre_topo_lib.sh for more details. |
| # |
| # Test for "tc action mirred egress mirror" when the device to mirror to is a |
| # gretap or ip6gretap netdevice. Expect that the packets come out encapsulated, |
| # and another gretap / ip6gretap netdevice is then capable of decapsulating the |
| # traffic. Test that the payload is what is expected (ICMP ping request or |
| # reply, depending on test). |
