Subject: [BlueZ PATCH v2] doc:adding definitions for load default params mgmt op
Date: Thu, 21 May 2020 14:47:27 +0000
Message-ID: <20200521144728.243834-1-alainm@chromium.org> (raw)

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.
