Chuck Lever a31b2f9392 xprtrdma: Connection becomes unstable after a reconnect ... This is because xprt_request_get_cong() is allowing more than one RPC Call to be transmitted before the first Receive on the new connection. The first Receive fills the Receive Queue based on the server's credit grant. Before that Receive, there is only a single Receive WR posted because the client doesn't know the server's credit grant. Solution is to clear rq_cong on all outstanding rpc_rqsts when the the cwnd is reset. This is because an RPC/RDMA credit is good for one connection instance only.
