+
+ ath9k_hw: set ANI firstep as absolute values instead of relative
+
+ On older chips, the INI value differ in similar ways as cycpwr_thr1, so
+ convert it to absolute values as well.
+
+ Since the ANI algorithm is different here compared to the old
+ implementation (fewer steps, controlled at a different point in time),
+ it makes sense to use values similar to what would be applied for newer
+ chips, just without relying on INI defaults.

+
+ ath9k_hw: set ANI cycpwr_thr1 as absolute values instead of relative
+
+ The table was copied from the ANI implementation of AR9300. It assumes
+ that the INI values contain a baseline value that is usable as reference
+ from which to increase/decrease based on the noise immunity value.
+
+ On older chips, the differences are bigger and especially AR5008/AR9001
+ are configured to much more sensitive values than what is useful.
+
+ Improve ANI behavior by reverting to the absolute values used in the
+ previous implementation (expressed as a simple formula instead of the
+ old table).
