OK, I thought we cannot guarantee the automatic power regulation, using lower values for now, it would be nice to implement the required mechanism to assure tx power regulation, but then how to define the two values? two tables, or a flag like "NO-APC -3" indicating that, without tx power regulation, there is a lower limit for tx power? 
And the patch:
