Subject: [Bluez PATCH] btmgmt: Add support to enable LL privacy
Date:   Mon,  5 Apr 2021 20:28:02 +0530
Message-Id: <20210405145802.27317-1-sathish.narasimman@intel.com>

If the Bluetooth controller supports LL privacy this command will be
used to test the same.
"sudo btmgmt power off"
"sudo btmgmt llprivacy on"
"sudo btmgmt power on"
