USB devices running at SuperSpeedPlus report "10000" or "20000" in
their sysfs speed attribute. usbip currently maps only "5000" to
USB_SPEED_SUPER, so a SuperSpeedPlus device is imported as
USB_SPEED_UNKNOWN.
The attach request is then rejected by vhci_hcd:
vhci_hcd: Failed attach request for unsupported USB speed: UNKNOWN
Map the SuperSpeedPlus sysfs speed values to USB_SPEED_SUPER_PLUS, use
the SuperSpeed VHCI hub for SuperSpeedPlus devices, and recognize the
gadget current_speed string used by the kernel.
Fixes: b2316645ca ("usb: show speed "10000" in sysfs for USB 3.1 SuperSpeedPlus devices")
