One approach is that when the OASIS v1 spec is published, this driver
is updated to match that and moved out of the intel directory.

This IPU/DPU/SmartNIC/.. device highly programmable. I assume a goal
is to make sure that the device meets the new v1 spec. That quite
likely requires a firmware update, but that is fine.
