Juuso Oikarinen 606c1487ac wl1271: Configure rates for templates
Configure meaningful rates to be used with the templates. For control frames,
use the determined basic rates (currently the lowest rate for the band) and
for data-frames (null-funcs) let the firmware use the current rate policy to
determine the rate.
