So far it has not been enabled for the networking driver yet but this series changes that. There is one snag though: the second generation (Intel Falcon Ridge) had a bug that needs special quirk to get it working. We had that in the early stages of the Thunderbolt/USB4 driver but it got dropped because it was not needed at the time. Now we add it back as a quirk for the host controller (NHI). The first patch of this series is a bugfix that I'm planning to push for v6.0-rc. Rest are v6.1 material. This also includes a patch that shows the XDomain link type in sysfs the same way we do for USB4 routers and updates the networking driver module description.
