In stream mode, when fast-forwarding TRBs, the stream number is not cleared causing the new stream to not get assigned. So we don't want controller to carry on transfers when short packet is received. So disable the CSP for stream capable endpoint. This is based on the 3.30a Programming guide, where table 3-1 device descriptor structure field definitions says for CSP bit If this bit is 0, the controller generates an XferComplete event and remove the stream. So if we keep CSP as 1 then switching between streams would not happen as in stream mode, when fast-forwarding TRBs, the stream number is not cleared causing the new stream to not get assigned.

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.
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.
