Goal: Provide a vhost/vDPA device as a pod secondary interface through ovn-k CNI. Supported cards are NVIDIA CX-6 DX and BF2.

Problem: Providing an open and standard (secondary) interface for accessing VFs/sub function from container workloads directly to NICs/smartNICs

Why is this important?
vDPA provides an open and standard interface for containers and VMs which removes the vendor lock in.

After having provided virtio/vDPA as a primary interface (dev-preview feature in 4.13), our current goal is to add vhost-vDPA support for CNV, kata containers and DPDK use cases (secondary interface).
