Bug 2093267

Cause: The RPS cpu mask was set to the reserved CPUs taken from the performance profile for all interfaces by default. Consequence: This is not practical for sriov-vfs and similar interfaces that carry RAN payload traffic as this is not scalable. Fix: 1. Set RPS cpu mask to reserved CPUs taken from the performance profile excluding physical and veth interfaces. 2. Add a new annotation A new annotation option to the performance profile: "performance.openshift.io/enable-physical-dev-rps". When added to a performance profile,it will enable RPS mask setting with systemd for all network devices by including physical interfaces from netdev-rps rule. Usage example for enabling RPS mask for all network interfaces: Oc edit <performanceprofile> for existing profiles OR when creating a new performance profile add the following annotation: - apiVersion: performance.openshift.io/v2 kind: PerformanceProfile metadata: annotations: performance.openshift.io/enable-physical-dev-rps: "true" spec: cpu: reserved: <reserved cpus set> When set to "true" - set RPS mask to the reserved cpus set for all network interfaces. When omitted or set to false - set RPS mask to net interfaces excluding physical and veth interfaces. (default behavior) Result: - RPS mask setting defaults for net interfaces excluding physical and vetch devices. - An annotation added to included all net interfaces as described in the fix section.
