To cancel requests, I think that TID is sufficient.  To allow canceling response MADs (e.g. large RMPP), you need something like: TID, SGID or SLID, and class.  wr_id seemed simpler.

Outside of deregistration, I doubt it.  But we could add this call, and let deregistration call it, or force users to call it before deregistering.
