My understanding is that for --specific-- MR, its associated rkey would
wrap every 256 mappings see ib_update_fast_reg_key and friends. And
anyway, for specific MR you can have only one mapping living at any
point of time (e.g set before sending the request, invalidated remotely
with the response or locally after getting the response)
Or.
