Magnus Karlsson feb973a909 selftests/xsk: add varying payload pattern within packet
Add a varying payload pattern within the packet. Instead of having
just a packet number that is the same for all words in a packet, make
each word different in the packet. The upper 16-bits are set to the
packet number and the lower 16-bits are the sequence number of the
words in this packet. So the 3rd packet's 5th 32-bit word of data will
contain the number (2<<32) | 4 as they are numbered from 0.

This will make it easier to detect fragments that are out of order
when starting to test multi-buffer support.

The member payload in the packet is renamed pkt_nb to reflect that it
is now only a pkt_nb, not the real payload as seen above.

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.
