The ConnectX NIC series hardware provides the advanced internal
MMU option and can operate directly ob virtual addresses, host
software should not do any virtual-to-physical address translations.
It means the mlx5 PMDs can operate in DPDK IOVA VA (virtual address)
mode transparently.
To force IOVA VA mode the DPDK should be built with meson option:
enable_iova_as_pa=false
With this option only drivers supporting IOVA VA mode are enabled.
This patch marks mlx5 drivers with require_iova_in_mbuf flag,
thus allowing their compilation for IOVA VA mode.
