WAN Interface Statistics not working correctly

[Component0002]

Hello,

I have upgraded my firewall to a Mellanox ConnectX-3 Pro from an Intel 4 port 1Gbps NIC. I reinstalled Opnsense enabled the kernel module with mlx4en_load=YES, edited the interface names in my config and reimported it.

Everyone works correctly apart from the Interface Statistics on the Dashboard. This will regularly go down even though I'm not restarting the firewall.

For example, currently it is at 1.73GB bytes out but if I check back in a few minutes it will be at 1.2GB bytes out. I have also had it regularly go to 18.45E which I believe is 18.45 Exabytes. This happens within minutes of the firewall having started so it is obviously not true as I only have a 900Mbps line...

Furthermore, when this happens it breaks the live traffic graph and the units are all wrong. I have confirmed that this bug happens with 26.1.9 and also with 26.1.10 now.

This was never an issue with the Intel card so I'm wondering if it is an issue with the driver? The VLAN Interface Statistics display without any issues.

How do I resolve this issue? I have checked the logs but I can't see any errors here.

After the interface change the reporting database might have become corrupted. Just a guess.
Perhaps resetting would help? Reporting > Settings > Reporting Database Options.
There are options to reset / repair but beware, I imagine there could be data loss. I am not certain if the actions taken are destructive.
In the past when I changed interface hardware I had to do this. It didn't matter to me if resetting would reset to zero data but it fixed my reporting problem similar to yours.
