This patchseries adds the USB 3.1 groundwork.
USB 3.1 specification includes a new SuperSpeedPlus protocol supporting
up to 10Gbps speeds. USB 3.1 devices using the new SuperSpeedPlus protocol
are called USB 3.1 Gen2 devices.
Devices announce their SuperSpeedPlus capability with a new SuperSpeedPlus
device capability descriptor included in the device BOS descriptor.
I short, this series does for
usb core:
Parse and store the new SuperSpeedPlus capability descriptor
Allow hosts to define themselves as USB 3.1 capable
xhci:
Check if host hardware support USB 3.1 and define hcd as USB 3.1 capable
Create a SuperSpeedPlus descriptor for the roothub that support USB 3.1
Support the USB 3.1 get ext port status hub requests which returns
more detailed information about port speed, not yet used by usb core.
latest usbutils source supports parsing the SuperSpeedPlus capability
descriptor. With this patchseries lsusb -v shows a SuperSpeedPlus
capability descriptor for the xhci USB 3.1 roothub
