Hi Jog,
The missing link in connecting applications which receive packets from port
80/443 and DPDK itself is the TCP/IP stack in use. DPDK itself does not include
any stack, so you'll need to select a stack to use with your applications. The
mechanics of how apps talk to ports and how traffic gets filtered to them is
largely the stack's responsibility.
