If I use 10Gb copper cards (X520-AT2), I connect cable to 10G switch and got 10Gb link. If I remove cable from 10Gb switch and connect it to 1G switch i have got 1Gb link from my device. But for 82599ES 10g SFI/SFP+ (fiber cars) I have problems. If I connect cable to 10G switch and start DPDK application I have got 10Gb link, but if I remove cable (without rte_eth_dev_stop), and connect it to 1Gb switch I have no link. If I connect cable to 1G switch and start DPDK application I have got 1Gb link, but if I remove cable (without rte_eth_dev_stop), and coonect it to 10Gb switch I have no link. In other words, the connection is not established at a different speed link without restarting the application. On the linux(kernel driver) the link speed changes successfully without any resets and restarts. Did anyone have a similar problem? Have any ideas what is wrong? --- Best regards, Leonid Myravjev
