The only time we transfer data (rather than issuing a command) out of the AP->command TX endpoint is when we're clearing the hardware pipeline. All that's needed is a "small" data buffer, and its contents aren't even important. For convenience, we just transfer a command structure in this case (it's already mapped for DMA). The TRE is added to a transaction using ipa_cmd_ip_tag_status_add(), but we ignore the size value provided to that function. So just get rid of the size argument.

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.
