If you need every module to use the stack, I fail to see the value in
having them be separate - it just seems error prone.  For a client to
use RC services for example, it will need to (based on module names)
depend on the CM module, the SA client module, the query module, the MAD
module, and probably others.  These services should not be treated as
independent - they are intertwined, and IMO their functionality should
be exposed as a whole, not in little pieces.  Ideally, there should be
one transport module that ULPs interface to which exposes a single
consistent API, and one module per HCA that expose HCA functionality to
the transport, again with a single consistent API.
