xprtrdma: Handle stale connection rejection
A server rejects a connection attempt with STALE_CONNECTION when a client attempts to connect to a working remote service, but uses a QPN and GUID that corresponds to an old connection that was abandoned. This might occur after a client crashes and restarts. Fix rpcrdma_conn_upcall() to distinguish between a normal rejection and rejection of stale connection parameters. As an additional clean-up, remove the code that retries the connection attempt with different ORD/IRD values. Code audit of other ULP initiators shows no similar special case handling of initiator_depth or responder_resources. Signed-off-by:Chuck Lever <chuck.lever@oracle.com> Signed-off-by:
