[PATCH] net: enable wireless core features with WIRELESS_ALLCONFIG

[Mark Salyzyn]

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 core features to provide the API surface for them to load.

Introduce CONFIG_WIRELESS_ALLCONFIG to select all wireless core
features by activating all the hidden configuration options, without
having to specifically select any wireless module(s).

this looks rather legacy Wireless Extension (wext) specific. So it might be better to clearly name the option “legacy” and “wext” to not confuse anybody running an actual modern driver and userspace.
