Hi,
My "Ethernet controller: Intel Corporation Ethernet Controller 10G X550T (rev
01)" device stopped working on recent kernel builds (fails to show up in 'ifconfig'
or to get an IP address). I bisected the failure down to the following commit:
commit a0285236ab93fdfdd1008afaa04561d142d6c276 (HEAD, refs/bisect/bad)

ixgbe: add initial devlink support
[..]
Normally, the device is given a name like enp194s0f0 and connects to the wired network.
now the name is likely to be different, please see this thread:
https://lkml.org/lkml/2025/4/24/1750
Is it possible that your network setup script has some part of interface
discovery hardcoded?
Starting with this patch, it fails to do so. I'm not familiar with how to
debug this particular device, so please let me know what other information
would be of assistance.
