      External PCIe is the raison d'ĂȘtre of Thunderbolt. It has been supported on Linux for a few years now. Several laptop vendors have Thunderbolt attached docking stations. The devices in the dock appear in 'lspci' output.

        Thunderbolt *is* PCIe (+ displayport).
        Besides, the way the news is written makes you think that thunderbolt networking currently does not work under linux but I've got a thunderbolt port since 3 years on my macbook pro which always worked just fine with a thunderbolt <-> ethernet adapter (which is basically an external PCIe network card).

            So, if device's (laptop) documentation states, that it contains Thunderbolt compatible/certified USB-C, then that port certainly supports DisplayPort Alternate Mode?

            Is DP Alternate mode for Thunderbolt the same thing as DP Alternate mode for USB-C? Or, does it somehow differ, ie. initiation/negotiation of used protocol?

              I wasn't as lucky. I got a work laptop (Fifth gen Lenovo thinkpad x1 carbon) and a compatible Lenovo thunderbolt 3 dock, and pretty much expected everything to work under Linux. Well, the only thing that actually works on the dock are the displayports and HDMI. No USB, no Ethernet. Tried with newest kernel versions as well. No luck.

                Much of the consumer Thunderbolt 3 hardware was plagued by firmware issues early on. I would see if there's any available firmware updates for the laptop and/or the dock.

                  Thunderbolt 3 and DP are both alternate modes for USB-C. There isn't a DP alternate mode for Thunderbolt 3 as such, however thunderbolt 3 ports (almost?) always support DP too.

                    Thunderbolt in its currentl revision is limited to DisplayPort 1.2, while there is no such limit for DisplayPort alternate mode.
