Dear all, I am a beginner with DPDK. I just install it in fedora18 with two X540 Enthercards.
After compile it and run the testpmd I got the following message: ==================================================================== [root at localhost test-pmd]# ./testpmd -c7 -n3 -- -i --nb-cores=2 --nb-ports=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: Setting up hugepage memory...
