Disclaimer: I don't have the hardware you're talking about.

However, I took a quick look at the mainline kernel drivers and the
driver sources from mellanox.com - the mainline kernel does _NOT_
have the code for these files.

I guess if you want to use that, you'll have to install the ofed
driver from mellanox.com (preferably by starting with the sources
for Ubuntu 20.04).

PS: [1] looks like up to date documentation
