+         *      using info->driver_data or info->rate_driver_data. Thus,

+         *      the same problem occurs, since we need info->control.vif
+         *      internally.
+         *
+         *      To fix this, we should send the frame through TX processing
+         *      again. However, it's not that simple, since the frame will
+         *      have been software-encrypted (if applicable) already, and
+         *      encrypting it again doesn't do much good. So to properly do
+         *      that, we not only have to skip the actual 'raw' encryption
+         *      (key selection etc. still has to be done!) but also the
+         *      sequence number assignment since that impacts the crypto
+         *      encapsulation, of course.
+         *
+         *      Hence, for now, fix the bug by just dropping the frame.
