I will make my question a bit more specific ..

While doing a scan, do we require to know the signal strength.. The 
driver in question is the dst .. If we do not need to know the signal 
strength the dst will tune a bit more faster, since instead of 2 
messages that are sentto the MCU/ASIC, only one need to be sent.


Hence tuning will be faster, as i2c communication also takes a while to 
happen, and to retrieve the signal strength on a frequency that does not 
exist, it takes really a while to return back and can be a cause for 
irritation ..

So i was thinking about removing the get_signal() call itself during a 
scan ..

Any comments .. ?
