My apologies. I think there was a miscommunication. I assumed Jakub's
question was directed towards you. I have no objection to making it a
generic param; I will do so in v4. It sounded to me like Jakub was
wanting more information on what exactly this setting does beyond what I
was able to provide in the commit message and mlx5 devlink
documentation. My understanding is that this setting pertains to tx
csums and how the device expects the driver to prepare partial csums
when doing tx cso. I don't really know more than that. Especially not
something like what the FW's role in implementing this is.
