New API for port representors introduced in DPDK, for switch application like OVS.

While running DPDK reduces the CPU overload of interrupt driven packet processing, CPU cores are still not completely freed up from polling of packet queues. We already implemented accelerated through HW offloads saves CPU cycles consumed for flow look ups.

To solve this challenge, DPDK switch app is further accelerated through internal HW switch offloads of virtual port like SR-IOV. Port representors for switches already introduced in DPDK and we present how OVS-DPDK will use it.

We introduce a classification and forward methodology that enables a full offloading datapath to the NIC hardware.

We present the open source work being done in the DPDK and OVS communities and significant performance gains achieved. We also present how this work can be extended to VXLAN and other tunneling traffic.
