+Subject: Reduce undesired logging of ACL rejection events from AP mode
+
+When Probe Request frame handling was extended to use MAC ACL through
+ieee802_11_allowed_address(), the MSG_INFO level log print ("Station
+<addr> not allowed to authenticate") from that function ended up getting
+printed even for Probe Request frames. That was not by design and it can
+result in excessive logging and MSG_INFO level if MAC ACL is used.
+
+Fix this by printing this log entry only for authentication and
+association frames. In addition, drop the priority of that log entry to
+MSG_DEBUG since this is not really an unexpected behavior in most MAC
+ACL use cases.
+
+Fixes: 92eb00aec2a0 ("Extend ACL check for Probe Request frames")

+Subject: Drop logging priority for handle_auth_cb no-STA-match messages
+
+This message was printed and MSG_INFO level which would be more
+reasonable for error cases where hostapd has accepted authentication.
+However, this is not really an error case for the cases where
+authentication was rejected (e.g., due to MAC ACL). Drop this to use
+MSG_DEBUG level.
