Page count of rx_buffer needs to be stored prior to XDP call to prevent page recycling in case that buffer would be freed within xdp redirect path. Instead of storing it on the stack, now it is stored in the rx_buffer struct. This will help in processing multi-buffers as the page counts of all rx_buffers (of the same packet) don't need to be stored on stack.

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.
