Adding thunderbolt devices in Fedora server 30

I recently purchased a thunderbolt 3 to 10GbE adapter ( QNA-T310G1S ) for my homelab NUC ( NUC7i5BNH ) running Fedora server 30.

The network interface was not showing up when I connected the adapter. Some googling later and I figured out what I was not doing.

Thunderbolt devices need to be authorized and added to the thunderbolt device manager before they can be used. This requirement can be changed in the BIOS if desired.

Here’s how I added my 10GbE adapter.

Install the thunderbolt device manager.

>_ sudo dnf install bolt

List connected thunderbolt devices. Take note of the UUID.

>_ sudo boltctl list

Authorize and add the device to the device database.
