It is great to see description of counters, it would be good if all drivers did
this for xstats. There are some issues with the documentation that should be
addressed in later update.

The section number is wrong. It ends up as a subset of the "Testpmd driver specific
commands". It should be in the Statistics section.

The section headings overall for this NIC guide need to be reorganized/reworded.
Kind of mess now.
