From 6abdb651255784f1907d8c8fcbf7e4ba4196b1da Mon Sep 17 00:00:00 2001 From: David Ahern Date: Thu, 1 Aug 2019 11:56:41 -0700 Subject: selftests: Add ipv6 udp tests to fcnal-test Add IPv6 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 Signed-off-by: David S.
