That was exactly my point - if we take the checks out of the HCA
driver, they can't be eliminated - they have to be relocated (to the
proxy).  Currently, the proxy doesn't have to check if a work request
exceeds the limits of a QP (the proxy doesn't have that information),
so adding these checks in the proxy would actually complicate things.

However, this is something that I think we should do in version 2, and
the definitions of the QP structure (to expose its settings) would
facilitate that.
