From: Luiz Augusto von Dentz Date: Thu, 27 Oct 2022 23:18:04 +0000 (-0700) Subject: Bluetooth: Add CONFIG_BT_LE_L2CAP_ECRED X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=462fcd53924ccc21596d30edd0673fa7c939b392;p=linux.git Bluetooth: Add CONFIG_BT_LE_L2CAP_ECRED 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.
