1. Proposed title of this feature request
PCI Passthrough for Openshift Container Networking

2. What is the nature and description of the request?
A PCI Passthrough configuration which pushes the entire NIC to the container for packet processing.

We have contemplated using host-device for this, however, this particular request is aimed at NUMA awareness (though does not have to be entirely for NUMA awareness setups)

Other downsides to host-device:

1. Container would be tied to physical NIC
2. host-device works on kernel interface

This configuration would appear to be similar to the method established for CNV:
https://docs.openshift.com/container-platform/4.9/virt/virtual_machines/advanced_vm_management/virt-configuring-pci-passthrough.html

However, I do not think this helps to dedicate physical pci addresses to pods.

3. Why does the customer need this? (List the business requirements here)
There is a need to run containerized applications which perform packet processing.

4. List any affected packages or components.

• Openshift-SDN
• OVN-Kubernetes
• Multus
