Subject: [PATCH net-next 10/10] selftests: mlxsw: Add resilient nexthop groups configuration tests
From: Ido Schimmel <idosch@...dia.com>
Test that unsupported resilient nexthop group configurations are
rejected and that offload / trap indication is correctly set on nexthop
buckets in a resilient group.
