From 4450d96aa6b3cb3d7c909fb6a4b105f4c8ea4929 Mon Sep 17 00:00:00 2001 From: Mark Salyzyn Date: Fri, 30 Aug 2019 08:23:25 -0700 Subject: [PATCH] ANDROID: net: enable wireless core features with GKI_LEGACY_WEXT_ALLCONFIG In embedded environments the requirements are to be able to pick and choose 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_GKI_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).
