When a partial transfer is received, the driver should not submit any more segments to the hardware, as they will be ignored/unused until a new transfer start operation is done. This change implements this by adding a new flag on the AXI DMAC descriptor. This flags is set to true, if there was a partial transfer in a previously completed segment. When that flag is true, the TLAST flag is added to the to the submitted segment, signaling the controller to stop receiving more segments.

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.
