   4 Subject: wifi: rt2x00: disable RTS threshold for rt2800 by default
   5
   6 rt2800 has a lot of registers to control the RTS enable/disable
   7 status for different rates. And the driver control them via
   8 rt2800_set_rts_threshold(). When RTS was disabled in user
   9 interface, this function won't be called at all. This means that
  10 the RTS is still 'on' for CCK and OFDM rates. So we'd better to
  11 disable them by default because it should be like this. The RTS
  12 for HT20 and HT40 is already default off so we don't need to
  13 touch them. If we toggle the RTS status, these register bits
  14 will be enable/disable again by rt2800_set_rts_threshold().
