Linux kernel source tree

Two XSK tasks are performed during NAPI polling, that are not bound to hardware interrupts: TXing packets and polling for frames in the Fill Ring. They are special in a way that the hardware doesn't know about these tasks, so it doesn't trigger interrupts if there is still some work to be done, it's our driver's responsibility to ensure NAPI will be rescheduled if needed. Create a new function to handle these tasks and move the corresponding code from mlx5e_napi_poll to the new function to improve modularity and prepare for the changes in the following patch.

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.
