In embedded environments the requirements are to be able to pick and chose which features one requires built into the kernel. If an embedded environment wants to supports loading modules that have been kbuilt out of tree, there is a need to enable hidden configurations for legacy wireless core features to provide the API surface for them to load.
Introduce CONFIG_LEGACY_WEXT_ALLCONFIG to select all legacy wireless extension core features by activating in turn all the associated hidden configuration options, without having to specifically select any wireless module(s).

Config option used to enable all the legacy wireless extensions tothe core functionality used by add-in modules.If you are not building a kernel to be used for a variety ofout-of-kernel built wireless modules, say N here.config CFG80211 tristate "cfg80211 - wireless configuration API" depends on RFKILL || !RFKILL -- 2.23.0.187.g17f5b7556c-goog
How is this patch applicable to stable kernels???
