MCX312A-XCBT (dual SFP+, CX3 non-pro)
MCX312B-XCCT (dual SFP+, CX3 pro)

For anyone using these cards, can you guys confirm if mlxconfig (from the MFT tools) works for querying and setting their parameters (for setting up SRIOV).

I have to replace my MCX311A-XCAT (single SFP+, CX3 non-pro) card because mlxconfig doesn't work for it and the only workaround for this is to generate a new image with a modified ini but this means that I am limited to using an older fw (2.40.5300) which is a bummer. This is explained in detail in this thread. I simply need one 10Gb SFP+ port but cannot afford to use an older firmware with bugs that aren't fixed yet, even if this is just for a Proxmox homelab. And I absolutely hate Nvidia for not providing these custom mlx firmware packages anymore.
