Hi Jacob,
This is exactly how it's already implemented in mlx5, and I don't really
understand how firmware version is related? Is it specific to your
device firmware?
Maybe you can workaround that in the driver?

I feel like we're going the wrong way here having different flags
interpretations by different drivers.
