In DWC3, to prepare TRBs for streams, all the TRBs of a transfer will use the same stream ID. To start a new stream, the driver needs to wait for the current transfer to complete or ended (by END_TRANFER command). As a result, inform the controller of the last TRB of a transfer so that it knows when a transfer completes and start a new transfer of a new stream. Even though the transfer completion handling can be applied for other non-isoc endpoints, only do it for streams due to its requirement. It's better to keep the controller's TRB cache full than waiting for transfer completion and starting a new transfer.

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.
