+/**
+ * DOC: Basic ANI Operation
+ *
+ * Adaptive Noise Immunity (ANI) controls five noise immunity parameters
+ * depending on the amount of interference in the environment, increasing
+ * or reducing sensitivity as necessary.
+ *
+ * The parameters are:
+ *   - "noise immunity"
+ *   - "spur immunity"
+ *   - "firstep level"
+ *   - "OFDM weak signal detection"
+ *   - "CCK weak signal detection"
+ *
+ * Basically we look at the amount of ODFM and CCK timing errors we get and then
+ * raise or lower immunity accordingly by setting one or more of these
+ * parameters.
+ * Newer chipsets have PHY error counters in hardware which will generate a MIB
+ * interrupt when they overflow. Older hardware has too enable PHY error frames
+ * by setting a RX flag and then count every single PHY error. When a specified
+ * threshold of errors has been reached we will raise immunity.
+ * Also we regularly check the amount of errors and lower or raise immunity as
+ * necessary.

- * mac80211 queues, ACs, hardware queues, FIFOs.
- *
- * Cf. http://wireless.kernel.org/en/developers/Documentation/mac80211/queues
- *
- * Mac80211 uses the following numbers, which we get as from it
- * by way of skb_get_queue_mapping(skb):
- *
- *      VO      0
- *      VI      1
- *      BE      2
- *      BK      3
- *
- *
- * Regular (not A-MPDU) frames are put into hardware queues corresponding
- * to the FIFOs, see comments in iwl-prph.h. Aggregated frames get their
- * own queue per aggregation session (RA/TID combination), such queues are
- * set up to map into FIFOs too, for which we need an AC->FIFO mapping. In
- * order to map frames to the right queue, we also need an AC->hw queue
- * mapping. This is implemented here.
- *
- * Due to the way hw queues are set up (by the hw specific modules like
- * iwl-4965.c, iwl-5000.c etc.), the AC->hw queue mapping is the identity
- * mapping.
