Subject: [PATCH 1/8] Bluetooth: Translate additional address type correctly
Date:   Mon, 13 Jul 2020 11:42:13 +0530
Message-Id: <20200713061220.3252-2-sathish.narasimman@intel.com>

From: Marcel Holtmann <marcel@holtmann.org>

When using controller based address resolution, then the new address
types 0x02 and 0x03 are used. These types need to be converted back into
either public address or random address types.
