In the downstream patch that adds support to XDP_REDIRECT-out, the XDP xmit frame function doesn't share the same run context as the NAPI that polls the XDP-SQ completion queue. Hence, need to re-order the XDP-SQ fields to avoid cacheline false-sharing. Take redirect_flush and doorbell out of DB, into separated cachelines. Add a cacheline breaker within the stats struct.

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
