Deploy TRex in Centos7.4

TRex based on DPDK, have high performance for traffics generator scenario. TRex has two deployment scenarios, one is Stateless mode, another is Server/client mode. How different for them? As follow pic. Btw, TRex has a GUI tool that can easy config traffic pattern, but that only support in Stateless mode. For Server/Client mode, only CLI (you can reference “Linux SRv6实战 (第三篇) 多云环境下Overlay(VPP) 和Underlay整合测试 ” that use Server/Client mode). For the article, only focus on stateless mode and GUI tool.
