Hi,

No, the CFG80211_WEXT is the old interface. I think there were some
plans to mark it deprecated. Anyway it should not be enabled by
default and almost none of configs enable it.

It is an fallback, not usual way of loading firmware. In typical cases
this should not be needed. Why Exynos defconfig should be exceptional
here?

Best regards,
Krzysztof
