I compared .map file between "changed code" and the original, they are same for both linux and bsd. In fact you had ACK'd v4 version of this patch series and no major changes after that. Please let me know if I missed something. dpdk-common-eal-f-4 has all the common code movement changes dpdk-tmp is original code #/home/rkerur/dpdk-common-eal-f-4/dpdk# diff lib/librte_eal/linuxapp/eal/rte_eal_version.map /home/rkerur/dpdk-tmp/dpdk/lib/librte_eal/linuxapp/eal/rte_eal_version.map #/home/rkerur/dpdk-common-eal-f-4/dpdk# diff lib/librte_eal/bsdapp/eal/rte_eal_version.map /home/rkerur/dpdk-tmp/dpdk/lib/librte_eal/bsdapp/eal/rte_eal_version.map Thanks, Ravi Neil > >
