+ * number of times got timeout when waiting for CTS/ACK/BA and energy was
+ * detected just after sending the RTS/DATA. this statistics may help getting

+ * due to collision and how many due to SNR.
+ * For Link-quality the CTS collision indication is more reliable then the ACK
+ * collision indication as the RTS frame is short and has more chance that the
+ * frame/s which caused the collision continue after the RTS was sent.

+ * @scd_query_agg: scheduler query allowed aggregation
+ * @scd_query_mismatch: scheduler query inaccurate, either too

+ * @agg_terminated_underrun: aggregation was terminated due to

+ * TX deffer on energy. This counter is reset on each successful transmit.
+ * When timer exceed TX deffer limit than will be uCode assert.

+ * @tx_deffer_base_time: Keep the time of the last successful
+ * transmit
+ * @tx_underrun: TX killed due to underrun

+ * @burst_terminated: Count burst or fragmentation termination
+ * occurrence
+ * @late_tx_vec_wr_cnt: ???
+ * TX is not sent because ucode failed to notify the TRM in SIFS-delta from
