Hello, @deven_zhu:

Thank you for contacting Intel Embedded Community.

We suggest using the latest version of the cited driver (Version: 2.13.10) and let us know the results. You can find it on the following website:

In case the problem persists, could you please let us know if the affected NIC card has been developed by you or by another developer? Could you please inform the name of the manufacturer, part number, and model of the affected units if they are developed by another company? On the other hand, could you please inform the part number of the Ethernet controller related to the affected design if it has been developed by you? 

We are waiting for your answer.

Best regards,
