selftests: Add ipv6 ping tests to fcnal-test
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. Signed-off-by: David Ahern <dsahern@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
