I said per ACL link. The Bluetooth specification defines that between
two devices one ACL and up to three SCO links can exists. The max number
of SCO links per piconet is also three. In BlueZ we currently allow one
ACL and one SCO link between two devices. This limitation is some kind
of historic. Feel free to fix it.
