| 2014-08-26 | thunderbolt: Clear hops before overwriting | Andreas Noever | |
| Zero hops in tb_path_activate before writing a new path. This fixes the following scenario: - Boot with a coldplugged device - Unplug device - Plug device back in - PCI hotplug fails The hotplug operation fails because our new path matches the (now defunct) path which was setup by the firmware for the coldplugged device. By writing zeros before writing our path configuration we can force thunderbolt to retrain the path.

| 2014-06-19 | thunderbolt: Add path setup code. | Andreas Noever | |
| A thunderbolt path is a unidirectional channel between two thunderbolt ports. Two such paths are needed to establish a pci tunnel. This patch introduces struct tb_path as well as a set of tb_path_* methods which are used to activate & deactivate paths.
