Hi, I try to use ibv_poll_cq to identify connectivity problems. The scenario is following, based on modified rping example:
1) preliminary steps done and rdma connection established between Client and Server, retry_count in rdma_conn_param is set 1; 2) Server lost its link (corresponding switch port disabled), Client is still connected to the switch; 3) Client calls ibv_post_send 4) Client polls cq with ibv_poll_cq and gets expected IBV_WC_RETRY_EXC_ERR after about 1 second. Can this timeout be decreased? If it is impossible, can you suggest something else? Used software is Ofed-1.5.3.1, IB device is Mellanox MT26428.
