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