> For the multiple hardware ports connect to a single DPDK port (mhpsdp),

> This patch introduces a new port affinity item in rte flow API, and
> the port affinity value reflects the physical port affinity of the
> received packets.
>
> While uses the port affinity as a matching item in the flow, and sets the

>
> This patch also adds the testpmd command line to match the new item:
> flow create 0 ingress group 0 pattern port_affinity affinity is 1 /
> end actions queue index 0 / end
>
> The above command means that creates a flow on a single DPDK port and
> matches the packet from the first physical port (assumes the affinity 1
> stands for the first port) and redirects these packets into RxQ 0.
