    Description

      When handling CM events, o2iblnd expects RDMA_CM_EVENT_ESTABLISHED to be received when the connection is either in IBLND_CONN_PASSIVE_WAIT or IBLND_CONN_ACTIVE_CONNECT state, otherwise LBUG occurs.

      Modify kiblnd_cm_callback() to handle this gracefully: report an error with relevant details and ignore the event rather than just crash.

      This has been reported in the field with RoCE v2 setup.
