retry_count, I assume, is for connection establishment? For the Chelsio

used. If there is no TCP listener, then the connection establishment
will fail immediately. If the node is not reachable, then normal TCP
retransmit rules apply, but once TCP gives up, then the rdma connection
establishment will fail.
On IB, this is a transport level retry of a lost request.
Ah, ok. Regardless, TCP handles all that for IWARP and we currently
don't provide the rdma application any way to manipulate the TCP behavior.
