An octeontx ethdev device consists of multiple PKO VF devices and an PKI VF device. On Octeontx HW, each Rx queues are enumerated as SSOVF device which is exposed as event_octeontx device, Tx queues are enumerated as PKOVF device, and ingress packet configuration is accomplished through PKIVF device. In order to expose as an single ethdev instance, On PCIe VF probe, the driver stores the information associated with the PCIe VF device and later with vdev infrastructure creates ethdev device with earlier probed PCIe VF device.
