Hello wlian17,

Thank you for posting in Intel Ethernet Communities. 

Please provide the ixgbe driver version loaded on your system as well as the firmware version of your X540 adapter. 

We would also appreciate if you can provide the PBA and serial number of the adapter. You may refer to the link below on where to find the PBA number. Providing the photos of the adapter focusing on the markings (white sticker) found on the physical card will do as well for us to double check on it. The PBA is consist of 6-digit number located at the last part of the serial number, it could help us identify if it is Retail or OEM version on Intel Ethernet adapter.
