Mike,
Ideally your right the ULP shouldn't care what HCA it's running on.
There are some practical reasons why an ULP might
want to know the vendor and part number it was using like for debug or
taking advantage a perform nuance of a particular
HCA.

I don't have anything planned to enumerate those values. I would
guess that only a very few ULPs should even look at them.
Why would this ever have to be examined by a ULP? This seems like a
low-level driver issue. Given the verbs semantics abstract the hardware,
aside from the HCA-specific driver, the rest of the stack should be unaware
of any thing below.
