"mlx5_net: Packet pacing is not supported" in gpunetio_send_wait_time

Host: DOCA 2.2.0
DPU: BF2, MBF2H332A-AEEO_Ax, FW 24.38.1002
DMA copy application can run successfully.

Follow this instruction to switch DPU to NIC mode .
Try to run GPUNetIO sample code, showing the following:

Is there any configuration I was missing? Thanks.

  1. Have you setup follow guide below?
    GPUNetIO Programming Guide :: NVIDIA DOCA SDK Documentation
  2. Have you run app on host?

Likely the DPDK can’t probe mlx5 driver. You can follow the DPDK guide to install.
