DPDK linux下安装

系统：ubuntu-14.04.3-desktop-amd64.iso 内核：3.19.0-25-generic， 低版本有问题

按照官网安装：

Quick start

"A simple forwarding test with pcap PMD which works with any NIC (with performance penalties)"

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

make过程可能会出现问题：

pcap.h not found! 解决办法：sudo apt-get install libpcap-dev

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

            运行：build/app/testpmd -c7 -n3 --vdev=eth_pcap0,iface=eth0 --vdev=eth_pcap1,iface=eth1 -- -i --nb-cores=2 --nb-ports=2 --total-num-mbufs=2048
