Send an RDMA-CM private message on connect, and look for one during a connection-established event. Both sides can communicate their various implementation limits. Implementations that don't support this sideband protocol ignore it. Once the client knows the server's inline threshold maxima, it can adjust the use of Reply chunks, and eliminate most use of Position Zero Read chunks. Moderately-sized I/O can be done using a pure inline RDMA Send instead of RDMA operations that require memory registration. Signed-off-by:
