In preparating for hardware timestamping, we need to support large Tx and Rx completion descriptors. Here we add the new queue feature ids and handling for the completion descriptor sizes. We only are adding support for the Rx 2x sized completion descriptors in the general Rx queues for now as we will be using it for PTP Rx support, and we don't have an immediate use for the large descriptors in the general Tx queues yet; it will be used in a special Tx queues added in one of the next few patches.

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.
