So i know that most people still have "ethX".
But i like the "Predictable Interface Names" and therefore use them.
Only my "new" chelsio cc2-n320e-rs dual 10g sfp+ card doens't play nice for some reason?

It gives me a "renameX" interface. with is not editable in the GUI and is "random" therefor not predictable.

Motherboard is a X10SLM-F

Google doesn't give me any clue in whats happening other then "use the eth0" and "use the /etc/udev/rules.d/70-persistent-net.rules"

Hi,

do you have the problem if you use Kernel "pve-kernel-4.15.18-9" ?

I really don't want to tag you but i think this really needs some love as you guys are generating the kernel.

The name is generated also by the nic driver and the bios.
The problem is we have no chelsio nic so we can't reproduce it here.
I can only recommend you to use the udev rules to set the nic name manual.
