I will be traveling Monday and Tuesday, so I probably won't get to
post the patch until Wednesday (US/California time).

To answer your question, no, you will not be able to pass a VAPI
handle directly to the CM.  The only change will be to the HCA
provider -- I'll add an interface to register a VAPI QP handle.
You'll call ib_qp_create with a device_specific parameter and get back
a struct ib_qp * that you can pass to the CM.  It's a little wasteful
but it seems like the best solution until we have final resolution on
what our verbs API looks like.
