Not that you should be seeing an issue but just so you are aware only DPD 1.7.0 is supported by OVS... there wasn't an official port to 1.7.1
You usually see this issue if the module was built with another kernel version that isn't the currently running version

Try rebuilding the igb_uio module using the script $DPDK_DIR/tools/setup.sh
