      iwlwifi: cleanup spectrum measurement command support · 81963d68
      Reinette Chatre 提交于
      In iwlagn the support for spectrum measurement command has been
      disabled since v2.6.29 without any requests for it. In addition to this
      when this command is indeed enabled it has been found to trigger firmware
      SYSASSERT on at least 4965 and 5100 hardware (see
      http://bugzilla.intellinuxwireless.org/show_bug.cgi?id=1952 ). Since then
      this code has been bitrotting and cannot just be enabled without porting.
      
      Remove support for spectrum measurement command from iwlagn. It can be
      added back if there is a future need and the firmware problem it triggers
      has been fixed. Support for the spectrim measurement notification remains
      as it has been enabled all the time.
      
      In addition to this remove the 3945 spectrum measurement command Kconfig
      option and make this command always supported. The code added by this
      enabling is minimal and only run when user triggers a spectrum measurement
      request via sysfs.

      iwlwifi: configure missed beacon threshold · a13d276f
      Wey-Yi Guy 提交于
      Add support to configure missed beacon threshold, by default, if receive
      "missed beacon" notification from uCode and has more than 5 consecutive
      beacon missed, then perform sensitivity calibration; with this change,
      allow user to adjust the missed beacon threshold from debugfs in case
      more sensitivity calibration required for better performance in noisy
      environment
      
      The default value (=5) should be good enough for the normal condition,
      but for very noisy environment, more sensitivity calibration could help
      improve the throughput, so by setting the missed beacon threshold to
      lower number, user might experience better performance result.

      that power saving does not work well on 3945. Since then power saving has
      also been connected with association problems where an AP deathenticates a
      3945 after it is unable to transmit data to it - this happens when 3945
      enters power savings mode.
      
      Disable power save support until issues are resolved.

      In iwlwifi, priv->alloc_rxb_page is used to keep track of the Rx
      pages allocated by the driver. This cleans up the page free routines
      by introducing __iwl_free_pages/iwl_free_pages so that the accounting
      is more accurate and less error prone. This also fixes two instances where
      the counter was not updated.

      iwlwifi: LED cleanup · e932a609
      Johannes Berg 提交于
      The iwlwifi drivers have LED blinking requirements that
      mac80211 cannot fulfill due to the use of just a single
      LED instead of different ones for TX, RX, radio etc.
      Instead, the single LED blinks according to transfers
      and is solid on the rest of the time. As such, having
      LED class devices registered that mac80211 triggers are
      connected to is pointless as we don't use the triggers
      anyway.
      
      Remove all the useless code and add hooks into the
      driver itself. At the same time, make the LED code
      abstracted so the core code that determines blink rate
      etc. can be shared between 3945 and agn in iwlcore.
      
      At the same time, the fact that we removed the use of
      the mac80211 LED triggers means we can also remove the
      IWLWIFI_LEDS Kconfig symbol since the LED support is
      now self-contained.
