This seems rather wrong, most (extended) features require the driver/device to actually *do* something. Let's say you enable NL80211_EXT_FEATURE_TXQS - but then nothing actually happens when you try to configure those. Or let's say you enable NL80211_FEATURE_TX_POWER_INSERTION but then nothing actually happens when sending the frame... johannes
