It's one chapter in the overall "Rawdev Drivers" document:
https://doc.dpdk.org/guides/rawdevs/index.html
Since the (R) symbol doesn't seem to show up correctly in what you have above (though it looks correct to me), I suggest just referring to the "IOAT Rawdev Driver" chapter in the "Rawdev Drivers" document.
[Marcin] Ok, I will change it like that.
