For EPPKE, I will handle it like this:

@@ -1598,6 +1598,15 @@ int ieee80211_register_hw(struct ieee80211_hw *hw)
                local->sband_allocated |= BIT(band);
        }
 
+       /*
+        * mac80211 supports EPPKE, if the driver supports (Re)Association
+        * frame encryption
+        */
+       if (wiphy_ext_feature_isset(local->hw.wiphy,
+                                   NL80211_EXT_FEATURE_ASSOC_FRAME_ENCRYPTION))
+               wiphy_ext_feature_set(local->hw.wiphy,
+                                     NL80211_EXT_FEATURE_EPPKE);

For IEEE 802.1X Authentication, I am thinking to advertise its support directly
from mac80211, in ieee80211_alloc_hw_nm, without checking for (Re)Association encryption
support from the driver.
