Thunderbolt Networking is supported on both Thunderbolt(tm) 2 and Thunderbolt(tm) 3 systems.  
Thunderbolt 2 systems must have updated NVM (version 25 or later) in order for the functionality to work properly.  
If the system does not have the update, please contact the OEM directly for an updated NVM.  
For best functionality and support, Intel recommends using Thunderbolt 3 systems for all validation and testing.

This is WIP, once this patch will be upstream, we will be able to focus more
on aligning Linux with the Thunderbolt features that we have for windows.
