        }


        for= (int i =3D 0; i < m_config.queue_tx_count; i++) {
        &nb= sp;   if(!rte_eth_tx_queue_setup(m_portId, i, m_config.queue_tx_desc, = rte_eth_dev_socket_id(m_portId), &ethInfo.default_txconf))
        &nb= sp;       std::cout << "Setup tx queue successful= ly socket id : " << rte_eth_dev_socket_id(m_portId) << &qu= ot;\n";
        &nb= sp;   else
        &nb= sp;   {
        &nb= sp;       std::cout << "Setup tx queue ERROR\n&qu= ot;;
        &nb= sp;       return false;
        &nb= sp;   }
        }

Then I am starting memif eth device with these;

        = if( rte_eth_promiscuous_enable(m_por= tId) !=3D 0) {
        &nb= sp;   std::cout << "rte_eth_promiscuous_enable error\n"= ;;
        &nb= sp;   return false;
        }
        els= e
        &nb= sp;   std::cout << "rte_eth_promiscuous_enable success \n&q= uot;;


        if(= !rte_eth_dev_start(m_portId)) {
        &nb= sp;   std::cout << "Eth dev is started \n";
        }
        els= e {
        &nb= sp;   std::cout << "Eth dev is start ERROR \n";
        &nb= sp;   return false;
        }

I am running client memif after I run memif server (third independent proce= ss). When I check the client memif link status with rte_eth_link_get, memif client link status is down and DPDK g= iving 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 r= un server memif ?
If it is possible, how can I achieve that.

Thank you,
Best Regards
