# 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).
