Update to the Kconfig Thunderbolt description to add Thunderbolt networking as an option. The menu item "Thunderbolt support" now offers: "Apple Hardware Support" (existing) and/or "Thunderbolt Networking" (new) You can choose the driver for your platform or build both drivers - each driver will detect if it can run on the specific platform. If the Thunderbolt Networking option is chosen, Thunderbolt Networking will be enabled between Linux non-Apple systems, macOS and Windows based systems. Thunderbolt Networking will not affect any other Thunderbolt feature that was previous available to Linux users on either Apple or non-Apple platforms.
