+ * This is an workaround for several undocumented bugs.
+ * Don't mess with the QoS/AC <-> HW Queue map, if you don't
+ * know what you are doing.
+ *
+ * Known problems [hardware]:
+ *  * The MAC does not aggregate frames on anything other
+ *    than the first HW queue.
+ *  * when an AMPDU is placed [in the first hw queue] and
+ *    additional frames are already queued on a different
+ *    hw queue, the MAC will ALWAYS freeze.
+ *
+ * In a nutshell: The hardware can either do QoS or
+ * Aggregation but not both at the same time. As a
+ * result, this makes the device pretty much useless
+ * for any serious 802.11n setup.
