From: Jerin Jacob <jerinj at marvell.com>

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

Deprecation is planned for v20.08 release.
