It is both drivers and the userland tools that you get in the tarball. This stuff is often developed by people with a focus on hardware. They will build something to work well on their machine but may never have used a different linux distro. The userland tools might assume compile options in libraries will be as they are in redhat. There will be hard coded paths where there shouldn’t be. The source may not be available, it might be static binaries. That kind of stuff.
