The option iommu=group_mf indicates the that the iommu driver should expose all functions of a multi-function PCI device as the same iommu_device_group. This is useful for disallowing individual functions being exposed as independent devices to userspace as there are often hidden dependencies. Virtual functions are not affected by this option.
