Proxmox 8 and i40e driver kernel 6.2

[Joe Botha]

Hi

After upgrading to Proxmox 8.0, I tried to build the latest intel i40e driver, but I get an error.

I'm guessing kernel 6.2 is a bit too new for the intel drivers.

i40e driver: 2.22.20
kernel: 6.2.16-3-pve

Error:

i40e_ptp.c: In function ‘i40e_ptp_create_clock’:
/usr/src/i40e-2.22.20/i40e_ptp.c:1561:21: error: ‘struct ptp_clock_info’ has no member named ‘adjfreq’

Suggestions? Wait for intel, or use driver in the kernel?

ethtool -i eno8
driver: i40e
version: 6.2.16-3-pve

Or, I guess I can try install pve-kernel-6.1.10-1-pve

Why do you need to build i40e driver ? the version include in stock 6.2 kernel is not recent enough ?

Hi

The intel i40e driver has some extra features and optimisations, in theory. We have been using the intel driver for a long time with x710 NICs. I changed one of our servers to the in-kernel driver a few minutes ago - it seems fairly happy, but I get some errors at startup - with both the in-kernel and intel drivers.

do you use vlan aware bridge ?

I'm seeing a similar bug report here : https://forum.proxmox.com/threads/error-i40e_aq_rc_enospc-forcing-overflow-promiscuous-on-pf.62875/

if yes, can you try to add in /etc/network/interfaces

iface <interface> inet manual
    pre-up /usr/sbin/ethtool -K <interface> rx-vlan-filter off

(replace <interface> by your interface name.

(you need to install ethtool, apt install ethtool)
