Hi,

I found Qemu start to support virtio-net RX RSS:

If VIRTIO_NET_F_RSS negotiated and RSS is enabled, process
incoming packets, calculate packet's hash and place the
packet into respective RX virtqueue.

If I understand it correct, in order for DPDK to support Virtio-net RX RSS 
in Qemu/KVM guest, the DPDK Virtio PMD also needs to support RX RSS, is 
that right? if so, any plan to enhance Virtio PMD to support RX RSS ?

Regards,

Vincent
