Subject: [PATCH v3 02/13] Bluetooth: Support reading of codecs supported over l2cap socket
Date: Mon, 15 Nov 2021 12:19:03 +0530 [thread overview]
Message-ID: <20211115064914.2345-2-kiran.k@intel.com> (raw)
In-Reply-To: <20211115064914.2345-1-kiran.k@intel.com>
Codecs supported for A2DP offload use case are returned over l2cap
socket. Add BT_CODEC option to getsockopt to return the codecs.
