| # | |
| # 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). | |
