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().
