It's too lack of information in commit message.
You should add such what values are acceptable for which purpose by each 
param_id and param_value to make this changes meaningful to community.

Thanks,

i agree. i reviewed the firmware sourcecode to find out what its doing, 
but also within the firmware is almost undocumented. its a bunch of 
undocumented
numeric parameters with undocumented behaviour.
if qca is willig to document this feature it might be included.
