What's SCC? Does none of the generic versions fit the bill?
https://docs.kernel.org/next/networking/devlink/devlink-info.html#generic-versions
If not you still have to document the meaning of this component
in Documentation/networking/devlink/hns3.rst

SCC means "soft congestion control", which is similar to fw.roce, but not exactly the same.
It is a firmware dedicated to providing congestion control for roce,

OK, I will describe this inDocumentation/networking/devlink/hns3.rst
