For that one should understand eal_init sequence first. Should know about _option_device_parse and rte_bus_scan() dependency. After that bus_scan is a need for _get_iommu_class() of api to know that - kdrv is igb/uio/vfio etc.. That's why. Refer work history. Again V9 series happened not for fun. I diagress on your comment.
