Lennart Poettering ec541c569b hwdb,rules: mark host-to-host network devices as only requiring link local addressing
This is a generalization of this logic:

https://github.com/NetworkManager/NetworkManager/blob/main/data/90-nm-thunderbolt.rules

It applies not just to thunderbolt, but to any kind of device, even
matched by vendor/product, via hwdb.

I added two entries for Prolific PC-to-PC devices (of which I have one
lying around).
