Andrew:

As per the design, the Accelerator Function Unit (AFU)
for this new IBM CXL Flash Adapater retains the same host
interface as the previous generation. For the early prototypes
of the new card, the driver with this change behaves exactly as
the driver prior to this behaved with the earlier generation
card. i.e. No card specific changes are required. However, I
left the staging comment in there, in case later versions of the
card deviate from the prototype.
