Dpdk Use Memif in secondary process

Hello,
I am using memif in our applications. In my case, I have to use memif in secondary process. I can use memif ( as a server ) in secondary process. Running primary process "./primaryProc --proc-type=primary --file-prefix=pmd1 --vdev=net_memif,role=server,socket=/tmp/memif.sock, socket-abstract=no" like that and then running secondary process "./secondaryProc --proc-type=auto --file-prefix=pmd1" like that. Also, I configure memif eth device and start at secondary process. With that way I can run memif as a server in secondary process, but I have to implement it as a client. By doing the same steps, as I did the for the server memif, I cannot be able to run client memif in secondary process. These are the configurations that I am doing for memif eth device at secondary process. ( In my implementations, I always give full arguments to primary process then configure / initialize and start the memif eth devices in secondary process)

       if(!rte_eth_dev_get_port_by_name(m_name.c_str(),&m_portId))
            std::cout << "Get net_memif eth device successfully port id : " << m_portId << "\n";
        else
        {
            std::cout << "rte_eth_dev_get_port_by_name ERROR \n";
            return false;
        }

        auto eth_count = rte_eth_dev_count_avail();

        if(eth_count < 0)
            return false;


        if(!rte_eth_dev_info_get(m_portId,&ethInfo)) {

            std::cout << "Get eth dev info successfully\n";
            std::cout << " port id : " << m_portId <<"ethInfo : " << ethInfo.driver_name << "\n";
        }
        else
        {
            std::cout << "Get eth dev info ERROR\n";
            return false;
        }


        if(!rte_eth_dev_configure(m_portId, m_config.queue_rx_count, m_config.queue_tx_count, &ethConfig)) {

            std::cout << "Configure eth dev successfully\n";
        }
        else
        {
            std::cout << "Configure eth dev ERROR\n";
            return false;
        }

        if(!rte_eth_dev_adjust_nb_rx_tx_desc(m_portId, &m_config.queue_rx_desc, &m_config.queue_tx_desc))
            std::cout << "Adjust eth dev rx tx desc successfully\n";
        else
        {
            std::cout << "Adjust eth dev rx tx desc ERROR\n";
            return false;
        }

        for (int i = 0; i < m_config.queue_rx_count; i++) {
            if(!rte_eth_rx_queue_setup(m_portId, i, m_config.queue_rx_desc, rte_eth_dev_socket_id(m_portId), &ethInfo.default_rxconf, mempool))
                std::cout << "Setup rx queue successfully socket id : " << rte_eth_dev_socket_id(m_portId) << std::endl;
            else
            {
                std::cout << "Setup rx queue ERROR\n";
                return false;
            }
        }


        for (int i = 0; i < m_config.queue_tx_count; i++) {
            if(!rte_eth_tx_queue_setup(m_portId, i, m_config.queue_tx_desc, rte_eth_dev_socket_id(m_portId), &ethInfo.default_txconf))
                std::cout << "Setup tx queue successfully socket id : " << rte_eth_dev_socket_id(m_portId) << "\n";
            else
            {
                std::cout << "Setup tx queue ERROR\n";
                return false;
            }
        }

Then I am starting memif eth device with these;

        if( rte_eth_promiscuous_enable(m_portId) != 0) {
            std::cout << "rte_eth_promiscuous_enable error\n";
            return false;
        }
        else
            std::cout << "rte_eth_promiscuous_enable success \n";


        if(!rte_eth_dev_start(m_portId)) {
            std::cout << "Eth dev is started \n";
        }
        else {
            std::cout << "Eth dev is start ERROR \n";
            return false;
        }

I am running client memif after I run memif server (third independent process). When I check the client memif link status with rte_eth_link_get, memif client link status is down and DPDK giving debug output something like "Resource temporarly unavailable" but server memif link up . Which I did not face with server memif implementation.

Could you give me clue or the reason, why I cannot run client memif, as I run server memif ?
If it is possible, how can I achieve that.

Thank you,
Best Regards
