Subject: [PATCH v9 0/8] thunderbolt: Introducing Thunderbolt(TM) Networking

This driver enables Thunderbolt Networking on non-Apple platforms
running Linux.

Thunderbolt Networking provides peer-to-peer connections to transfer
files between computers, perform PC migrations, and/or set up small
workgroups with shared storage.

This is a virtual connection that emulates an Ethernet adapter that
enables Ethernet networking with the benefit of Thunderbolt superfast
medium capability.

Thunderbolt Networking enables two hosts and several devices that
have a Thunderbolt controller to be connected together in a linear
(Daisy chain) series from a single port.

Thunderbolt Networking for Linux is compatible with Thunderbolt
Networking on systems running macOS or Windows and also supports
Thunderbolt generation 2 and 3 controllers.

Note that all pre-existing Thunderbolt generation 3 features, such as
USB, Display and other Thunderbolt device connectivity will continue
to function exactly as they did prior to enabling Thunderbolt Networking.

Code and Software Specifications:
This kernel code creates a virtual ethernet device for computer to
computer communication over a Thunderbolt cable.
The new driver is a separate driver to the existing Thunderbolt driver.
It is designed to work on systems running Linux that
interface with Intel Connection Manager (ICM) firmware based
Thunderbolt controllers that support Thunderbolt Networking.
The kernel code operates in coordination with the Thunderbolt user-
space daemon to implement full Thunderbolt networking functionality.

Hardware Specifications:
Thunderbolt Hardware specs have not yet been published but are used
where necessary for register definitions.
