Quick Start Guide

Extract sources

  tar xf dpdk.tar.gz
  cd dpdk

Enable pcap (libpcap headers are required).

  make config T=x86_64-native-linuxapp-gcc
  sed -ri 's,(PMD_PCAP=).*,\1y,' build/.config

Build libraries and test application (Linux headers may be needed with default config).

  make

Reserve huge pages memory.

  mkdir -p /mnt/huge
  mount -t hugetlbfs nodev /mnt/huge
  echo 64 > /sys/devices/system/node/node0/hugepages/hugepages-2048kB/nr_hugepages

Run poll-mode driver test (with a cable between ports).

  build/app/testpmd -c7 -n3 --vdev=net_pcap0,iface=eth0     --vdev=net_pcap1,iface=eth1 --
                  -i --nb-cores=2 --nb-ports=2 --total-num-mbufs=2048
