Sorry, you're late to the party :( We have now added the ability to
read page pool stats via netlink. The support was merged as
a379972973a80924b1d03443e20f113ff76a94c7.

If you use the page pools in your driver in a normal way (each page
pool only used by one NAPI instance and one netdev) you should use
that instead of dumping the stats into ethtool -S.
