Open data plane on dpdk, TCP/IP stack for dpdk.

####TCP/IP stack for dpdk

Netdp is porting from FreeBSD TCP/IP stack, and provide a userspace TCP/IP stack for use with the Intel dpdk.

• librte_netdp: TCP/IP stack static library. netdp use dpdk mbuf, ring, memzone, mempool, timer, spinlock. so zero copy mbuf between dpdk and netdp.

• librte_netdpsock: Netdp socket lib for application, zero copy between netdp and application.

• netdp_cmd: Command for configure netdp tcp/ip stack.

• netdp_test: Example application with netdp for testing netdp tcp/ip stack
