It looks crazy to restart the feature from scratch, not showing the fixes.
But after a quick look, there was so many lines and functions to fix
that it is maybe a good idea.
At least, the history will be clear.

It is just for correct alignment.

It reverts a change you made in ixgbe patch.

This include is not needed in this new version of xstats.

I will remove also the changes to release notes (API section),
as the API is not modified. They are just additional functions.
