I have a network that uses VLAN 201 and PPPoE, with kernel 6.2.9-200.fc37.x86_64 it works fine, but with kernel 6.2.10-200.fc37.x86_64 the inerface does not come up.

Reproducible: Always

Steps to Reproduce:
1. Setup VLAN 201 and PPPoE on a network interface

My NM config file (with password and email modified) /etc/NetworkManager/system-connections/pppoe-clpppoe.nmconnection has:


[connection]
id=pppoe-clpppoe
uuid=cc4f254d-9a7c-43de-8096-74d9c5eb6946
type=pppoe
interface-name=clpppoe
timestamp=1673535574
zone=umbrella_wan

[ethernet]

[ppp]
mtu=1492

[pppoe]
parent=vlan201
password=example
username=example

[ipv4]
dns=127.0.0.1;
dns-search=example.org;
ignore-auto-dns=true
method=auto

[ipv6]
addr-gen-mode=stable-privacy
ip6-privacy=0
method=disabled

[proxy]



Actual Results:  
Network fails to come up, it fails with:

Apr 17 06:42:14 umbrella NetworkManager[1312]: <info>  [1681738934.9325] audit: op="connection-activate" uuid="cc4f254d-9a7c-43de-8096-74d9c5eb6946" name="pppoe-clpppoe" result="fail" reason="Failed to find a compatible device for this connection"


Expected Results:  
Network comes up and is usable.

I looked for open bugs but didn't find any.

I'm not sure what other config and log files to attach - let me know if other details are needed.

Using the older kernel avoids the problem, so I assume it's a kernel change causing the problem.

The actual network device shows up, so it seems to be an issue with the VLAN or PPPoE.
