Place the associated RPC transaction's XID in the upper 32 bits of each RDMA segment's rdma_offset field. There are two reasons to do this: - The R_key only has 8 bits that are different from registration to registration. The XID adds more uniqueness to each RDMA segment to reduce the likelihood of a software bug on the server reading from or writing into memory it's not supposed to. - On-the-wire RDMA Read and Write requests do not otherwise carry any identifier that matches them up to an RPC. The XID in the upper 32 bits will act as an eye-catcher in network captures.
