I have a certain amount of state regarding a peer. I lookup that state based on the qp_num returned within a work completion, for example. If I reconnect, I will need to migrate the state from the old qp_num to the new qp_num. I have no preference which is why I asked about the two options (opening a socket to coordinate state transitions versus connecting with a new QP).
