2023-11-14 Thread Mario Limonciello
The USB4 spec specifies that PCIe ports that are used for tunneling PCIe traffic over USB4 fabric will be hardcoded to advertise 2.5GT/s and behave as a PCIe Gen1 device. The actual performance of these ports is controlled by the fabric implementation. Callers for pcie_bandwidth_available() will
