Boot messaged from PCIe tunneling=yes+

1. Please describe the problem:
When using a TB4 dock from Lenovo with a Network device that device crashes in case the TB4 dock is attached with "PCIe tunneling : Yes" in the BIOS.
If you do not enable this, the network device is instead identified as a usbnet and works.

2. What is the Version-Release number of the kernel:
6.3.8-200.fc38.x86_64

3. Did it work previously in Fedora? If so, what kernel version did the issue
   *first* appear?  Old kernels are available for download at
   https://koji.fedoraproject.org/koji/packageinfo?packageID=8 :

Probably is there longer - did not test with older kernels and the device itself is new.

4. Can you reproduce this issue? If so, please provide the steps to reproduce
   the issue below:

- Use a TB4 (40B0) dock from Lenovo and attach to a T14s laptop with "PCIe tunneling" set to yes in the BIOS
- boot the system with the network cable attached to the docks network port
- The network port crashes shortly after the boot.


5. Does this problem occur with the latest Rawhide kernel? To install the
   Rawhide kernel, run ``sudo dnf install fedora-repos-rawhide`` followed by
   ``sudo dnf update --enablerepo=rawhide kernel``:

Not tested.

6. Are you running any modules that not shipped with directly Fedora's kernel?:

No. (I think) this is a CSB.

7. Please attach the kernel logs. You can get the complete kernel log
   for a boot with ``journalctl --no-hostname -k > dmesg.txt``. If the
   issue occurred on a previous boot, use the journalctl ``-b`` flag.

Attached - let me know if you need a boot with no PCIe tunneling enabled.
