Dear DPDK experts. Thank you very much for your best great efforts and precious answers. I have a problem in setting up DPDK 2.1.0 in Fedora OS release 20 (Heisenbug). My problem is that I cannot receive any traffics in test-pmd. There are 2 nics (2 port NIC), I connected port 0 to port 1(loopback), port 2 to port3 (loopback). I attached details of my setup. I also attached my DPDK setup shell script. Did I miss something? or Is there any my mistakes? I will really appreciate if you check them and I can be given any advice and answers. It is important for me and urgent job. Thank you very much. Sincerely Yours, Ick-Sung Choi. * test-pmd log. $ sudo ./build/app/testpmd -c 0xF -n 4 -- -i --portmask=0xF --nb-cores=3 EAL: Detected lcore 0 as core 0 on socket 0 EAL: Detected lcore 1 as core 1 on socket 0 EAL: Detected lcore 2 as core 2 on socket 0 EAL: Detected lcore 3 as core 3 on socket 0 EAL: Detected lcore 4 as core 4 on socket 0 EAL: Detected lcore 5 as core 8 on socket 0 EAL: Detected lcore 6 as core 9 on socket 0 EAL: Detected lcore 7 as core 10 on socket 0 EAL: Detected lcore 8 as core 11 on socket 0 EAL: Detected lcore 9 as core 12 on socket 0 EAL: Detected lcore 10 as core 0 on socket 1 EAL: Detected lcore 11 as core 1 on socket 1 EAL: Detected lcore 12 as core 2 on socket 1 EAL: Detected lcore 13 as core 3 on socket 1 EAL: Detected lcore 14 as core 4 on socket 1 EAL: Detected lcore 15 as core 8 on socket 1 EAL: Detected lcore 16 as core 9 on socket 1 EAL: Detected lcore 17 as core 10 on socket 1 EAL: Detected lcore 18 as core 11 on socket 1 EAL: Detected lcore 19 as core 12 on socket 1 EAL: Support maximum 128 logical core(s) by configuration.
