Thanks for your reply. Yes, I am talking about the Intel N3000 FPGA accelerator card. Forgive my ignorance, does that imply a XX710 device? I rebuilt using DPDK v 19.11.7 but got the same result: i.e. rte_eth_dev_count_avail() returns 0. I can try using DPDK 20.11 but that will take a little while as I need to adjust to the new meson build environment. Would that be a good next move? David
