[dpdk-dev] Lcore-vports-queues mapping

[kuldeep.samasi at wipro.com]

I am using OVDK (dpdk openvswitch ), where I need to enhance the packet processing speed on DPDK data path by modifying lcore-- port-- queue mapping .

What application are you using? DPDK is primarily a set of libraries, and contains some apps purely as examples or for testing.
