On some xHCI controllers (e.g. Rockchip RK3399/RK3328/RK1808), they need to enable the ENT flag in the TRB data structure to force xHC to pre-fetch the next TRB of a TD. This patch add a new quirk to enable the ENT flag. And this patch also avoids to enable the ENT flag in the following two cases: 1. The transfer length of the first TRB isn't an integer multiple of the EP maxpacket. 2. The EP support bulk streaming protocol.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
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.
