+* **Add support for SW-assisted VDPA live migration.**
+  This SW-assisted VDPA live migration facility helps VDPA devices without
+  logging capability to perform live migration, a mediate SW relay can help
+  devices to track dirty pages caused by DMA. IFC driver has enabled this
+  SW-assisted live migration mode.
