Message-Id: <20190801185648.27653-9-dsahern@kernel.org>
Date: Thu, 1 Aug 2019 11:56:41 -0700

Subject: [PATCH net-next 08/15] selftests: Add ipv6 udp tests to fcnal-test
From: David Ahern <dsahern@...il.com>
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.
