    thunderbolt: Add support for DMA tunnels · 44242d6c
    Mika Westerberg authored
    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.
