| Subject: selftests: forwarding: vxlan_bridge_1d: Fix vxlan ecn decapsulate |
| value |
| |
| From: Hangbin Liu <liuhangbin@gmail.com> |
| |
| [ Upstream commit 5aa3c334a449bab24519c4967f5ac2b3304c8dcf ] |
| |
| 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 ] |
| |
