Subject: Virtio-PMD speed limits to 100Gbps, while hardware supports 200Gbps

Hi Team,

  I am using virtio-net, virtio-pci  drivers for a Bittware hardware. I 
could see the data is sent and received with the throughput of 100Gbps.
But the hardware supports for 200Gbps. I am not able to get the 
throughput more than 200Gbps.

I am using latest DPDK source files and I tested TestPMD application to 
transfer and receive packets. I have noticed the virtio_ethdev.c 
supports 200G, but while testing TX and RX shows 100Gbps.
I have increase CPU cores to more than 6 for each TX and RX. Still the 
throughput remains in 100Gbps.

Could you please let me know what changes to be made and what debug area 
I should look into.?

Thanks and regards,
Ayshathul Thuhara
