 Dear All,
 
 I'm new to DPDK and try to implement
 below scenario in my physical box having DPDK supported 1GB
 two port NIC( 82575EB)
 
 Connectivity scenario :
 PC laptop (via cross cable+static
 IP)----> [DPDK physical Box]- DPDK port 0 -->
 L2forwarder -->DPDK port 1 ---> Internet router/Gw.
 
 Environment :
 
 DPDK 16.11.1 + Ubuntu 
 
 My Objective is below:
 
 1) connect PC via DPDK forwarding
 application reside in DPDK physical box to Internet home
 router and monitor real time traffic while browsing.(The
 DPDK box act as bridge between Internet and client PC.)
 
 2) Implement QoS for the same traffic
 (source IP based)
 
 I try to achieve it, but no much
 success, as my forwarding PC able to ping one way after put
 ARP entry as mentioning gateway IP as DPDK port 0 MAC , but
 no reply.
 
 A) Seeking your valuable advice how to
 configure/develop two way communication app based on L2/L3
 forwarder or any other example. 
 
 B)Is that required to bind user space
 TCP/IP stack with application to implement such scenario or
 it  can achieve via L2 or L3 forwarder?
 
 C) Advice on how to setup the physical
 connectivity.
 
 
 Note: I refer below discussions to get
 more clarity but not fully resolved my objective:

 Seeking your valuable advice to way
 forward.
 
 Thank you,
