It relies on x86 IO port scheme support for its working. The legacy virtio is only the consumer of RTE_KDRV_NONE in DPDK PCI subsystem. Legacy virtio removal will also optimize DPDK PCI enumeration management as it does not need to probe RTE_KDRV_NONE based devices anymore. Legacy virtio feature removal is planned in the v20.11 release.
