      ath10k/ath10k-ct: support multicast and management rate control · a399b607
      Sven Eckelmann authored
      Drivers with software rate control can directly use the selected multicast
      rate for multicast/broadcast frames and the minimal basic rate for
      management frames. But drivers with offloaded rate control algorithms must
      be informed about such upper layer decisions to configure the
      hardware/firmware.
      
      A new BSS_CHANGED_MCAST_RATE is introduced in mac80211 to automatically
      inform all drivers. ath10k can detect this event and forward it via WMI to
      the driver. The already existing BSS_CHANGED_BASIC_RATES can be used to
      select the management rate.
      
      Without the WMI commands, a low rate (not necessarily one from the basic
      rates) is used for bcast/mcast/management frames. This means that the
      /etc/config/wireless settings basic_rate and mcast_rate would have no
      effect on the rates selected by this driver for the mentioned frames.
