That's because iw output is misleading.  This driver uses CMD_EXTERNAL_AUTH to 
tell iwd/wpa_s to transfer SAE authenticate frames via CMD_FRAME (similar to how 
iwd does FT-Auth frames).

Unfortunately the kernel never dedicated an actual capability bit to tell 
userspace that CMD_EXTERNAL_AUTH is being used.  They just reuse the generic 
FEATURE_SAE.

Its still just 2, SAE_OFFLOAD and EXTERNAL_AUTH
