Subject: [PATCH] Bluetooth: Translate additional address type correctly
Date:   Tue,  7 Apr 2020 23:12:02 +0200
Message-Id: <20200407211202.1008128-1-marcel@holtmann.org>
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit
Sender: linux-bluetooth-owner@vger.kernel.org
Precedence: bulk

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.
