Subject: [PATCH net-next 06/15] selftests: Add ipv6 tcp tests to fcnal-test
From: David Ahern <dsahern@...il.com>
Add IPv6 tcp tests to fcnal-test.sh. Covers the permutations of directly
connected addresses, routed destinations, VRF and non-VRF, and expected
failures for both clients and servers. Includes permutations with
net.ipv4.tcp_l3mdev_accept set to 0 and 1.
