Technical Summary:
   This document specifies the format of RDMA-CM Private Data exchanged
   between RPC-over-RDMA version 1 peers as part of establishing a
   connection.  Such private data is used to indicate peer support for
   remote invalidation and larger-than-default inline thresholds.  The
   addition of the private data payload specified in this document is an
   OPTIONAL extension.  The RPC-over-RDMA version 1 protocol does not
   require the payload to be present.

Working Group Summary

   The working group was aligned on this work and it moved
   through the review process with good input but nothing contentious.
