i40e: Add initial devlink support
I am not able to boot normally. The console shows the message
Failed to start Raise network interfaces
Searching for this message on th internet produces some old discussions
that suggest to look at the file /etc/network/interfaces. That file on my
system contains:
# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).
source /etc/network/interfaces.d/*
# The loopback network interface
auto lo
iface lo inet loopback
auto enp24s0f0
iface enp24s0f0 inet dhcp
The problem is maybe with interface name... after this commit the interface
should contain port_name suffix. In your case the name should be
`enp24s0f0np0`.
Could you please check it?
Thanks for the feedback. But I'm not clear on how this would work. Does
there have to be one name for kernels before this patch and another name
for kernels starting with this patch? Or is the new name also acceptable
for older kernels?
The name of a network interface is configured by udev. And it takes
network interface attributes and compose a name for it. One of these
attributes is phys_port_name [1] and if it is provided then its value is
appended to the name.
Prior this commit the i40e driver didn't provided this attribute so the
name is (in your case) enp24s0f0. After this commit the value is
provided so it is appended -> enp24s0f0np0
Look at 'systemd.net-naming-scheme' man page for details how the
interface names are composed.
Thanks,
Ivan
