__qdio_allocate_fill_qdr() is meant to set up one specific queue descriptor in the QDR. But for this simple task, it gets passed a bunch of global structs and offsets - and then navigates through the structs to find its actual operands. Clean up all the complicated pointer chasing & index calculation, and just pass a descriptor and its associated queue struct. While at it also add some virt_to_phys() translations, to clarify that addresses in the QDR are meant to be absolute.

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.
