Dear Ettus team,
I followed the instruction of https://kb.ettus.com/Getting_Started_with_DPDK_and_UHD to enable dpdk for my X310, however I have an error when I execute benchmark_rate as sudo su [INFO] [UHD] linux; GNU C++ version 9.3.0; Boost_107100; UHD_4.0.0.0-93-g3b9ced8f EAL: Detected 4 lcore(s) EAL: Detected 1 NUMA nodes EAL: Multi-process socket /var/run/dpdk/rte/mp_socket EAL: No free hugepages reported in hugepages-1048576kB EAL: Probing VFIO support...

I have checked dpdk-devbind --status-dev net and get Network devices using DPDK-compatible driver ============================================ 0000:0e:00.0 '82599ES 10-Gigabit SFI/SFP+ Network Connection 10fb' drv=vfio-pci unused=ixgbe 0000:0e:00.1 '82599ES 10-Gigabit SFI/SFP+ Network Connection 10fb' drv=vfio-pci unused=ixgbe Network devices using kernel driver =================================== 0000:00:1f.6 'Ethernet Connection (4) I219-LM 15d7' if=enp0s31f6 drv=e1000e unused=vfio-pci 0000:02:00.0 'Wireless 8265 / 8275 24fd' if=wlp2s0 drv=iwlwifi unused=vfio-pci which seems to be fine. thank you for your help sincerely Kasim
