We have an application using DPDK on AWS and would like to port it to Azure. What would be recommended PMD to use? If I understand correctly, we can either use the Netvsc PMD or the vdev_Netvsc PMD. It seems the Netvsc PMD is newer.

An alternative is to use the mlx4 PMD by only attaching to the mlx NIC's PCI address. As I understand it, the concern is the mlx nic may not receive all the packets. We run a proprietary UDP based protocol on top of DPDK. Are all UDP packets guaranteed to be received by the mlx NIC?

Thanks,

Yang
