Most of the patch seems like a no-op, except this bit:

 	if (is_rts_frame(frame_control) || is_cts_frame(frame_control)) {
 		__set_bit(ENTRY_TXD_BURST, &desc.flags);
-		if (is_rts_frame(frame_control))
+		if (is_rts_frame(frame_control)) {
 			__set_bit(ENTRY_TXD_RTS_FRAME, &desc.flags);
+			__set_bit(ENTRY_TXD_ACK, &desc.flags);
+		} else
+			__clear_bit(ENTRY_TXD_ACK, &desc.flags);
 		if (control->rts_cts_rate)
 			tx_rate = control->rts_cts_rate;
 	}

Is this correct?  I'm not sure about the actual meaning of TXD_W0_ACK
(which keys off ENTRY_TXD_ACK)...
