From 5ce772f3b2d83c31eda5c2abdcd6cc4547ecc6c8 Mon Sep 17 00:00:00 2001 From: Fangyin Hu Date: Tue, 11 Apr 2017 00:31:33 -0700 Subject: Add the NSH SFC functional test cases. 1. Proxy Inbound test with 152/256/512/1024/1280/1518 Bytes VxLAN-GPE + NSH packet 2. Proxy Outbound test with 128/256/512/1024/1280/1518 Bytes VxLAN packet 3. SFC SFF test with 152/256/512/1024/1280/1518 Bytes VxLAN-GPE + NSH packet Separate the functional test bootstrap file to another code review.
