      b43: Rewrite TX power adjustment · 18c8adeb
      Michael Buesch authored
      
      
      This patch rewrites the TX power recalculation algorithms to scale better
      with changed enviromnent. If there's low
      TX traffic, the power will be checked against the desired values
      every 60 seconds.
      If there is high TX traffic, the check is redone every 2 seconds. This improves
      the reaction times a lot and confuses the rate control less.
      It will also reduce the time it initially takes to tune to a new TX power
      value. With the old algorithm it could take about 30 to 45 seconds to settle to
      a new power value. This will happen in about two to four seconds now.

      b43: Implement dynamic PHY API · ef1a628d
      Michael Buesch authored
      
      
      This patch implements a dynamic "ops" based PHY API.
      This is needed in order to conveniently support future PHY types
      to avoid the "switch"-hell.
      
      This patch does not change any functionality. It just moves lots
      of code from one place to another and adjusts it for the changed
      data structures.

      b43: Rewrite LO calibration algorithm · f5eda47f
      Michael Buesch authored
      
      
      This patch distributes the Local Oscillator calibration bursts over time,
      so that calibration only happens when it's actually needed.
      Currently we periodically perform a recalibration of the whole table.
      The table is huge and this takes lots of time. Additionally only small bits
      of the table are actually needed at a given time. So instead of maintaining
      a huge table with all possible calibration values, we create dynamic calibration
      settings that
      a) We only calibrate when they are actually needed.
      b) Are cached for some time until they expire.
      So a recalibration might happen if we need a calibration setting that's not
      cached, or if the active calibration setting expires.
      Currently the expire timeout is set to 30 seconds. We may raise that in future.
      
      This patch reduces overall memory consumption by nuking the
      huge static calibration tables.
      
      This patch has been tested on several 4306, 4311 and 4318 flavours.
