1. ip_fragmentation 畫出程式流程圖，從Function判斷要砍掉哪個
2. Remove unrelated functions, keep only initial and RTE setup then finally print ipv4 informations. Github
3. ONLY supply ipv4，TCP/UDP.
4. Sucess install OVS+DPDK and bind NIC with DPDK driver，but can't run DPDK example。
原本以為是 ./configure OVS的參數問題，看完官方文件覺得不是該問題。
