Thank you for the post. Just to double check if you are using the driver from this site?
No, i am not using this driver Intel® Network Adapter Driver for 82575/6, 82580, I350, and I210/211-Based Gigabit Network Connections for Linux*
i am using the igb driver 5.3.0
here is my output for ethtool
# ethtool -i front_sfp0
firmware-version: 1.61, 0x8000091f
Thank you for the reply. Where did you obtain the 5.3.0 driver? any chance you can try the driver on our website? Just to double check if your I350 is an onboard NIC or standalone network adapter that can be plugged in and pulled out? If it is an onboard NIC what is the brand and model of your system?
Please refer to the replies below.
