dpdk编译
1、下载：http://core.dpdk.org/download/
2、编译：http://core.dpdk.org/doc/quick-start/
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).

Some sample applications can be tested after building them.
make -C examples RTE_SDK=$(pwd) RTE_TARGET=build O=$(pwd)/build/examples
3、问题：
1）pcap.h not found! 解决办法：sudo apt-get install libpcap-de
2）hugepage设置失败
修改/etc/default/grub 中的 GRUB_CMDLINE_LINUX，然后运行 grub 更新并重启系统： //根据系统实际情况设置
default_hugepagesz=1G hugepagesz=1G hugepages=16 hugepagesz=2M hugepages=2048 iommu=pt intel_iommu=on isolcpus=1-13,15-27
grub2-mkconfig -o /boot/grub2/grub.cfg
