I purposely did not add DEVLINK as a dependency to netdevsim to make > the resource controller truly optional. Can add it if you prefer.
Oh, no, I don't mind. I just thought NETDEVSIM=y DEVLINK=m case will break the build, but I haven't tested. If it works perfect, let's not add unnecessary dependencies :) (FWIW the MAY_USE_DEVLINK dep is basically depend on DEVLINK || DEVLINK=n, so one can still build without devlink but if devlink is a module netdevsim will also have to be.)
