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.
