DWC_usb31 periodic transfer at 48K+ bytes per interval may need modification to the TX/RX packet threshold to achieve optimal result. Add properties to make it configurable. By default, periodic ESS TX and RX threshold are not enabled. To enable TX or RX threshold (host mode only), both packet threshold count and max burst size properties must be set to a valid non-zero value 1-16. DWC_usb31 programming guide section 1.2.3 and 1.2.4.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
