From: Luiz Augusto von Dentz <luiz.von.dentz@xxxxxxxxx> This adds CONFIG_BT_LE_L2CAP_ECRED which can be used to enable L2CAP Enhanced Credit Flow Control Mode by default, previously it was only possible to set it via module parameter (e.g. bluetooth.enable_ecred=1). Since L2CAP ECRED mode is required by the likes of EATT which is recommended for LE Audio this enables it by default.
