Ah, I see what you mean.

Here's what's happening:

net/wireless/Kconfig says:

config WEXT_CORE
	def_bool y
	depends on CFG80211_WEXT || WIRELESS_EXT


and net/Kconfig says:

if WIRELESS

source "net/wireless/Kconfig"
source "net/mac80211/Kconfig"

endif # WIRELESS


so WEXT_CORE actually depends on NET && WIRELESS && (CFG80211_WEXT || WIRELESS_EXT)
(that's what xconfig shows me).
But WIRELESS is not enabled.  Pooh.

I was already toying with making CONFIG_WIRELESS a real/usable kconfig symbol.
That may have to be done unless someone else comes up with another solution.
