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
So i was thinking about removing the get_signal() call itself during a
Any comments .. ?
