      [PATCH] mac80211: improved 802.11g CTS protection · 63fc33ce
      Daniel Drake authored
      
      
      Currently, CTS protection is partially implemented twice:
       1. via prism2 ioctls, only used by hostapd
       2. via STA beacon parsing, recorded in sta.use_protection but never used
          (other than printed in debugfs)
      
      Protection control should be implemented on a per-subif basis. For example,
      a single physical device may be running a soft AP on one channel, and a STA
      on another. The AP interface should use protection based on what hostapd told
      it, and the STA interface should use protection based on beacon parsing.
      These should operate independantly: one subif using protection should not
      influence the other.
      
      To implement this, I moved the use_protection flag into ieee80211_sub_if_data
      and removed the device-global cts_protect_erp_frames flag.
      
      I also made the PRISM2_PARAM_CTS_PROTECT_ERP_FRAMES write operation only
      available for AP interfaces, to avoid any possibility of the user messing with
      the behaviour of a STA.
