Enable rte_tm to support queue rate limitation configure.\n+2. Enable devargs to parse the quanta_size for IGP pacing.\n+\n+The packet pacing quality is heavily rely on FlexRan application/OS setup.\n+For DPDK validation, we will focus on:\n+1. Make sure queue rate limitation configuration take effect by measure the bandwidth.\n+2. Should not exceed the bandwidth that be limited by the DCF. \n+3. Not to break anything else.\n+\n+Prerequisites\n+=============\n+\n+Topology\n+--------\n+DUT port 0 <----> Tester port 0\n+\n+Hardware\n+--------\n+Supported NICs: Intel® Ethernet 800 Series E810-XXVDA4/E810-CQ\n+\n+Software\n+--------\n+dpdk: http://dpdk.org/git/dpdk\n+runtime command: https://doc.dpdk.org/guides/testpmd_app_ug/testpmd_funcs.html\n+\n+General Set Up\n+--------------\n+1.
