Interesting, the following might explain why my XL710 feels a bit sketchy then. ;-) # ethtool -i p4p1 driver: i40e version: 1.2.37-k firmware-version: f4.22.26225 a1.1 n4.24 e12ef Looks like the firmware on this NIC is even older. I tried to update the firmware with nvmupdate64e and the first thing I noticed is that you cannot update the firmware even with todays linux git. The tool errors out because it cannot access the NVM. Only with a recent net-next kernel I was able to update the firmware. ethtool -i p4p1 driver: i40e version: 1.2.37-k firmware-version: f4.33.31377 a1.2 n4.42 e1932 However during the update I got a lot of errors in dmesg.
