With the upcoming introduction of batching to XSK data path, performance wise it will be the best to have the ring descriptor count to be aligned to power of 2. Check if ring sizes that user is going to attach the XSK socket fulfill the condition above. For Tx side, although check is being done against the Tx queue and in the end the socket will be attached to the XDP queue, it is fine since XDP queues get the ring->count setting from Tx queues.

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.
