4 # This test uses standard topology for testing gretap. See
5 # mirror_gre_topo_lib.sh for more details.
6 #
7 # Test for "tc action mirred egress mirror" when the device to mirror to is a
8 # gretap or ip6gretap netdevice. Expect that the packets come out encapsulated,
9 # and another gretap / ip6gretap netdevice is then capable of decapsulating the
10 # traffic. Test that the payload is what is expected (ICMP ping request or
11 # reply, depending on test).
