          iwlwifi: apply filter flags directly
      
      broke 3945 under some unknown circumstances, as
      reported by Alex.
      
      Since I want to keep the direct application of
      filter flags on iwlagn, duplicate the code into
      both 3945 and agn and remove committing the
      RXON that broke things from the 3945 version.

      These are allocated with pci_alloc_consistent, so calling
      pci_dma_sync_single_for_cpu is incorrect usage of the API.  Remove this
      misuse and consequently avoid the following backtrace:

      iwlwifi: use long monitor timer to avoid un-necessary reload · 3198c68c
      Wey-Yi Guy authored
      For 5000 and 6000g2b series of devices, use long monitor timer to check
      stuck tx queues.
      
      .6000g2b series device, it is WiFi/BT combo device, there are some cases,
      tx queues are not move for a period of time because the WiFi/BT coex.
      
      .5000 series device, it is being reported firmware got reload more
      often than necessary, so extend the timer to avoid un-necessary reload.

      Change the name for monitor timer, also adding define for long monitor
      timer; long monitor timer can be used for the type of devices require longer
      time to determine the uCode is stuck on tx and needed reload.

      ipw2100: register pm_qos request before registering pci driver · 2f81b471
      John W. Linville authored
      It is necessary to call pm_qos_add_request prior to calling
      pm_qos_update_request.  It was revealed that ipw2100 has been
      doing this wrong since "pm_qos: Get rid of the allocation in
      pm_qos_add_request()" (commit 82f68251)
      added a WARN that results in the following backtrace:
