Sean, it seems that a rdma_unbind API is necessary for SDP SO_REUSEADDR support.
This should only remove association between the port and the id, without
affecting the CM state.
Reason: when SO_REUSEADDR is set, the port becomes usable immediately
after close call, but the QP must not be closed immediately -
rather its closed after graceful close or after timeout.
Thus I can not destroy the id, but the association with
port needs to be cancelled.
I'm in the process of adding rdma_set_option and rdma_get_option calls. If
SO_REUSEADDR support were added through these calls, can we come up with a
solution that doesn't require adding an rdma_unbind call?
