Re: [RFC PATCH rdma-next 1/2] RDMA/rxe: add local implicit ODP MR support

One clarification on the wording in the cover letter and patch 1/2
commit message: when I said the per-transport ODP caps describe
explicit ODP MR semantics, that was too strong. What I meant is that
this series leaves the existing per-transport caps unchanged and
implements only the local lkey implicit-MR access path, while
rejecting remote rkey, atomic, flush, and atomic-write uses of
implicit MRs.

The intended review question remains whether advertising
IB_ODP_SUPPORT_IMPLICIT is acceptable for that local-access-only
implicit operation matrix, or whether the cap should wait for broader
implicit coverage. I will reword this in a v2 if the series moves
forward.
