In OVP8-342, we provided a patch dpdk-16.11-igb_uio-map-dummy-dma-forcing-iommu-domain-attachmen.patch on dpdk 16.11. Then in LIN8-6807 we get dpdk 16.04 back and set to prefered dpdk version. Thus, in current dpdk 16.04, the patch dpdk-16.11-igb_uio-map-dummy-dma-forcing-iommu-domain-attachmen.patch is not available. Customer meet problem when they run their dpdk applications with dpdk 16.04 without the patch. Please provide the fix on dpdk 16.04 ASAP.
