Ceph RDMA error: Infiniband binding_port port not found

["Liu, Changcheng" <changcheng.liu@xxxxxxxxx>]

Hi all,
    I'm enableing Ceph-RDMA/iWARP function with X722 network interface
    card. But it always failed with "FAILED ceph_assert(active_port)".
    Does anyone know how to debug this problem?


    The RDMA/iWARP has worked with X722 NIC after verifying with below
    command:
         Server side: rping -s -a <server_ip> -vVd
         Client side: rping -c -a <server_ip> -vVd

    However, it always hit below error when enable Ceph under RDMA.
    The error log is below:
