mlx5 ethtool PCIe counters - data path direction is ambiguous

Can you explain the data path direction for the counter:

rx_pci_signal_integrity

Is it from the network point of view i.e. rx = data received from the network port

OR

Are they from the PCIe interface point of view i.e. rx = received from the PCIe root complex

Thanks

Hi Dean,

Please refer to the following community guide

https://community.mellanox.com/s/article/understanding-mlx5-ethtool-counters

rx_pci_signal_integrity

Counts physical layer PCIe signal integrity errors, the number of transitions to recovery due to Framing errors and CRC (dlp and tlp).

If this counter is raising, try moving the adapter card to a different slot to rule out a bad PCI slot. Validate that you are running with the latest firmware available and latest server BIOS version

Thanks,

Samer
