KNI loopback mode tests will have performance impact in this mode due to IOVA to KVA address translations. However, In KNI real world use cases, the performace impact will be based on Linux kernel stack and scheduler latencies. Performance varies based on the KNI use case. If bus iommu scheme is IOVA_DC and KNI module is loaded, DPDK chooses IOVA as PA as existing behaviour. During KNI creation, app's iova_mode details are passed to the KNI kernel module, accordingly kernel module translates PA/IOVA addresses to KVA and vice-versa.
