Subject: [PATCH net-next 04/15] selftests: Add ipv6 ping tests to fcnal-test
From: David Ahern <dsahern@...il.com>
Add IPv6 ping tests to fcnal-test.sh. Covers the permutations of directly
connected addresses, routed destinations, VRF and non-VRF, and expected
failures.
Setup includes unreachable routes and fib rules blocking traffic.
