Hello, I'm new to DPDK and I'm trying to setup a simple project to count packets. I'm using MoonGen to generate the traffic on one machine and can receive the data using traditional sockets on another machine. So I know that part works.
I've built dpdk 21.11 and I've tried to modify the example rxtx callbacks application to count packets, but it doesn't see any traffic. So I presume there's something wrong with my environment. Can you advise on how to verify that my environment is correct and what is the recommended setup for new projects? Should I be using the virtualisation interface vfio-pci or the other interfaces? I have mlx5, i40e and ice NICs available for test. For mlx5 dpdk-devbind suggests that vfio-pci is compatible whereas mlx5_core is a kernel driver, but trying to run with vfio-pci leads to: mlx5_common: No Verbs device matches PCI device 0000:01:00.0, are kernel drivers loaded? mlx5 seems to work correctly with MoonGen. Any help greatly appreciated, Simon
