Simplify packet validation in the xsk selftests by performing it at once for every packet. The current code performed this per batch and did this on copied packet data. Make it simpler and faster by validating it at once and on the umem packet data thus skipping the copy and the memory allocation for the temprary buffer. The optional packet dump feature is also simplified in the same manner. Memory allocation and copying is removed and the dump is performed directly on the umem data.

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.
