Variable size WQE means that each send Work Queue Entry to HW can use different WQE sizes as opposed to the static WQE size on the current devices. Set variable WQE mode for Gen P7 devices. Depth of the Queue will be a multiple of slot which is 16 bytes. The number of slots should be a multiple of 256 as per the HW requirement. Initialize the Software shadow queue to hold requests equal to the number of slots. Also, do not expose the variable size WQE capability until the last patch in the series.

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.
