In addition to PCIe and Display Port tunnels it is also possible to create tunnels that forward DMA traffic from the host interface adapter (NHI) to a NULL port that is connected to another domain through a Thunderbolt cable. These tunnels can be used to carry software messages such as networking packets. To support this we introduce another tunnel type (TB_TUNNEL_DMA) that supports paths from NHI to NULL port and back.
