From 5aa3c334a449bab24519c4967f5ac2b3304c8dcf Mon Sep 17 00:00:00 2001 From: Hangbin Liu Date: Fri, 19 Mar 2021 22:33:14 +0800 Subject: selftests: forwarding: vxlan_bridge_1d: Fix vxlan ecn decapsulate value The ECN bit defines ECT(1) = 1, ECT(0) = 2. So inner 0x02 + outer 0x01 should be inner ECT(0) + outer ECT(1). Based on the description of __INET_ECN_decapsulate, the final decapsulate value should be ECT(1). So fix the test expect value to 0x01. Before the fix: TEST: VXLAN: ECN decap: 01/02->0x02 [FAIL] Expected to capture 10 packets, got 0. After the fix: TEST: VXLAN: ECN decap: 01/02->0x01 [ OK ] Fixes: a0b61f3d8ebf ("selftests: forwarding: vxlan_bridge_1d: Add an ECN decap test") Signed-off-by: Hangbin Liu Signed-off-by: David S.
