Thank you for contacting Intel Embedded Community.
In order to be on the same page, could you please tell us if the NIC has been developed by you or a third party company? In case that it is a third party design, could you please give us all the information related to it? If it has been developed by you, could you please let us know if it has been reviewed by Intel?
Waiting for your reply with the information that should answer these questions.
