DPDeviceFile is used by Device Plugins to pass device data to CNIs, as defined in the device-info-spec. The name of the DPDeviceFile is defined by the device-info-spec as: <ResourceName>-<DeviceID>-device.json If the DPDeviceFile exists, the NPWG implementation makes a copy of the file and passes the name of the file to the delegate CNI via capabilityArgs as CNIDeviceFile. If the DPDeviceFile does not exist, the filename is still passed to the CNI. The CNI can create the file and popluate it if a device is created within the CNI. The name of the CNIDeviceFile is not defined by device-info-spec, but to ensure the name does not clash it is formed by the following unique triplet: [networkName, PodUUID, ifName] k8snetworkplumbingwg/network-attachment-definition-client repo has utility functions to abstract some of this functionality so it can be reused across Device Plugins, NPWG implementations and CNIs.
