Add support to describe device for parsing device options. As the first device option, add raw addressing. "Raw Addressing" mode (as opposed to the current "qpl" mode) is an operational mode which allows the driver avoid bounce buffer copies which it currently performs using pre-allocated qpls (queue_page_lists) when sending and receiving packets. For egress packets, the provided skb data addresses will be dma_map'ed and passed to the device, allowing the NIC can perform DMA directly - the driver will not have to copy the buffer content into pre-allocated buffers/qpls (as in qpl mode). For ingress packets, copies are also eliminated as buffers are handed to the networking stack and then recycled or re-allocated as necessary, avoiding the use of skb_copy_to_linear_data(). This patch only introduces the option to the driver. Subsequent patches will add the ingress and egress functionality.

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.
