E.g the platform I'm using doesn't have hardcoded headers and it can be configured based on the function the user would like to use. If the devices are hardcoded, then using configfs can be skipped altogether. In such cases, APIs like pci_epf_create() can directly be used by the drivers instead of going via configfs.
