In order to determine that it issues a stream of ICMP packets and checks if they are mirrored as expected. However, the mausezahn invocation missed the -6 flag to identify the use of IPv6 protocol, and was sending ICMP messages over IPv6, as opposed to ICMP6. It also didn't pass an explicit source IP address, which apparently worked at some point in the past, but does not anymore. To fix these issues, extend the function mirror_test() in mirror_lib by detecting the IPv6 protocol addresses, and using a different ICMP scheme. Fix __mirror_gre_test() in the selftest itself to pass a source IP address. Signed-off-by: Petr Machata Signed-off-by: David S.
