      ath9k_hw: fix PA predistortion HT40 mask · f1a8abb0
      Felix Fietkau authored
      
      
      The commit 'ath9k_hw: Disable PAPRD for rates with low Tx power' changed
      the code that sets the PAPRD rate masks to use only either the HT20 mask
      or the HT40 mask. This is wrong, as the hardware can still use HT20 rates
      even when configured for HT40, and the operating channel mode does not
      affect PAPRD operation.
      The register for the HT40 rate mask is applied as a mask on top of the
      other registers to selectively disable PAPRD for specific rates on HT40
      packets only.
      This patch changes the code back to the old behavior which matches the
      intended use of these registers. While with current cards this should not
      make any practical difference (according to Atheros, the HT20 and HT40
      mask should always be equal), it is more correct that way, and maybe
      the HT40 mask will be used for some rare corner cases in the future.

      ath9k: Use static const · 07b2fa5a
      Joe Perches authored
      
      
      Using static const generally increases object text and decreases data size.
      It also generally decreases overall object size.

      ath9k_hw: clean up per-channel calibration data · 20bd2a09
      Felix Fietkau authored
      
      
      The noise floor history buffer is currently not kept per channel, which
      can lead to problems when changing channels from a clean channel to a
      noisy one. Also when switching from HT20 to HT40, the noise floor
      history buffer is full of measurements, but none of them contain data
      for the extension channel, which it needs quite a bit of time to recover
      from.
      
      This patch puts all the per-channel calibration data into a single data
      structure, and gives the the driver control over whether that is used
      per-channel or even not used for some channels.
      
      For ath9k_htc, I decided to keep this per-channel in order to avoid
      creating regressions.
      
      For ath9k, the data is kept only for the operating channel, which saves
      some space. ath9k_hw takes care of wiping old data when the operating
      channel or its channel flags change.
