When running IOMMU enabled the user is actually interacting with IO addresses - not physical addresses. The value in the DPDK memseg array is the correct one in this case, and should be used at a higher priority than attempting to look up the address in /proc/self/pagemap (i.e. what rte_mem_virt2phy() does). Further, rte_mem_virt2phy() will always fail when running as an unprivileged user, but scanning the memory segments will work.
