Hi,
I tested with an Ubuntu server live and I got the same behavior. After further investigation, this particular card I have is a custom one from the QUANTA company. Based on the Linux hardware page, those integrated custom NICs are not supported. https://linux-hardware.org/?view=search&vendor=intel&name=x722#list .
I ended up putting in a new PCI one and it's working.
Thank you for your help.
