Dear DPDK experts. Thank you very much for your best great efforts and precious answers. As you suggested, I reinstalled newer version of Fedora 22. I succeeded to communicate test-pmd in Fedora 22 (linux kernel version 4.2.3-200.fc22.x86_64, DPDK 2.1.0). The steps are as follows. sudo yum install gcc sudo yum install kernel-devel sudo yum install libpcap-devel And then I patched the source codes as in http://dpdk.org/dev/patchwork/patch/6800/ Patchwork [dpdk-dev] kni: fix igb build with kernel 4.2. And then, I followed the quick start instructions from http://dpdk.org/doc/quick-start . The test-pmd example seems to work. Thank you very much. I have another problem. As in the following test-pmd log scripts, most of received packets are RX-error. The same errors are occurred in the Ubuntu OS computer (Ubuntu 14.04.1 LTS, kernel version : 3.13.0-34-generic, DPDK 2.1.0). If you have any advices or answers for the above problem, I will really appreciate. Thank you very much. Sincerely Yours, Ick-Sung Choi. ---------------------------------------------------------------------- test-pmd scripts: $ sudo ./build/app/testpmd -c 0xFF -n 4 -- -i --portmask=0x3 --nb-cores=2 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.
