When application tells the library the DMA device is bound to vfio, the IOMMU will be programmed for guest memory. v4: * Added the compatibility with IOVA_AS_PA. * Revised the commit log that the IOMMU capability is added for DMA device. * Changed single patch to patchset, added a new flag parsing in example. v3: * Fixed some typos. v2: * Fixed a format issue. * Added the dma unmap logic when device is closed.
