This change adds the definition for the load default parameter command.
In particular, this command is used to load default parameters for
various operations in the kernel. This mechanism is also expandable to
future values that may be necessary.
This will allow bluetoothd to load parameters from a conf file that may
be customized for the specific requirements of each platforms.

you asked me about naming and I was thinking this:
+Read Default System Configuration Command
+=========================================
+
+
+Set Default System Configuration Command
+========================================
+
+
+Read Default Runtime Parameters Command
+=======================================
+
+
+Load Default Runtime Parameters Command
+=======================================
The Default System is the actual configuration that you load before you power on the controller. These are really the default values for a lot of things. And I used “Read” to get the current settings and also with that the list of supported values. So you know what changes would actually be possible.
I called the other one “Set” since it can set/overwrite a few of these values or actually all. I don’t wanted to use “Load” since it is not replacing all of the values like what we have with the other load commands.
The Default Runtime would be then all values that can be tweaked while the controller is up and running.

Marcel
Hi Marcel,
This makes sense. I'll send a new set of patches shortly.
Thanks,
Alain
