rt2x00 uses these antenna_sel_{t,r}x fields,
but they are also set within the rate selection.
So with the ioctls taken out, the fields itself
will still be changed.
In the legacy Ralink drivers, antenna selection was based
on the rssi value. Since rate_control conrtrols the rate based
on (among other things) the rssi it could take control of these
2 fields as well.
