Missing device counters in ethtool

Two device counters outbound_pci_buffer_overflow and dev_out_of_buffer mentioned in the MLX5 documentation are not available in ethtool. I’m using a ConnectX-5 NIC with kernel version 5.15. Are these two counters not available in ConnectX-5 NICs or is it a driver issue?

Hello,

Please make sure the MLNX_OFED Latest LTS version (23.10-1.1.9.0) is installed, and that the latest LTS NIC Firmware is installed on the ConnectX-5.
Once all versions are aligned to latest LTS, please re-check for these counters.

If you still encounter any issues, please open a case at: enterprisesupport@nvidia.com, and it will be handled according to entitlement.

Best Regards,
Jonathan.
