I realized that there are some sample examples available in dpdk-rumptcpip,
and am currently trying the tcp_http_get example.

But the basic question still remains for me, without assigning an IPaddress
to the NIC which DPDK is controlling, how does the communication happen. In
more detail, what is the src_ipaddr in the packet being sent out.
