- * when passing out the frame to the driver again, we would be
- * passing completely bogus data since the driver would then
- * expect a properly filled info->control. In mac80211 itself
- * 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.
- *

- * (4) we get TX status before having processed the frame and
- * knowing that the STA has gone to sleep.
- *
- * This is actually quite unlikely even when both those events are
- * processed from interrupts coming in quickly after one another or
- * even at the same time because we queue both TX status events and

+ * To fix this, we should send the frame through TX processing

+ * 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
