selftests: Add ipv4 udp tests to fcnal-test
Add udp 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.udp_l3mdev_accept set to 0 and 1. Signed-off-by: David Ahern <dsahern@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
