DPDK-ANS基于 DPDK 的 TCP/IP 协议栈
ANS(Acceleted Network Stack) 是一个基于 DPDK 的 TCP/IP stack，可以运行在 linux userspace。用户可以自由添加、删除ether 接口和IP地址，添加、删除静态路由。
支持的环境
EAL is based on dpdk-1.7.0
Development enviroment is based on x86_64-native-linuxapp-gcc
TCP/IP stack is based on FreeBSD 10.0-RELEASE
支持的特性
Netdp initialize
Ether layer
ARP
IP layer
Routing
ICMP
TCP
UDP
Commands for adding, deleting, showing IP address
Commands for adding, deleting, showing static route
