Implement basic management operations for Tx queues. Allocate memory for submission and completion rings. Learn how to start the queues, stop them, and wait for HW to be idle. We call HW rings "descriptor rings" (stored in ring->desc), and SW context rings "buffer rings" (stored in ring->*_buf union). This is the first patch which actually touches CSRs so add CSR helpers. No actual datapath / packet handling here, yet.

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 reStructuredText 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.
