From: Luiz Augusto von Dentz <luiz.von.dentz@xxxxxxxxx> This introduces the initial support for Bluetooth 5.2 features: * ISO channels: + CIS/Unicast support + ISO socket family with QoS support - BIS/Broadcast not yet supported * L2CAP Enhanced Credit Based Flow Control Mode + Support all new procedures + New L2CAP socket mode - Initiating multiple connections at once does not map to any existing socket APIs * Monitor: + ISO packets support * Drivers: + H4 ISO packets support * Emulator: + CIS/Unicast emulation support - BIS/Broadcast emulation not yet supported * Userspace support to follow once Kernel changes are merged. Bluetooth 5.2 spec: https://www.bluetooth.org/docman/handlers/downloaddoc.ashx?doc_id=478726 ChangeLog: - v2: Only attempt to fix up packet type when an ISO connection exists, remove L2CAP_ECRED_MASK. - v3: Dropped USB changes since that has not clear way to support ISO packets with existing endpoints. Renamed ECRED to EXT_FLOWCTL.
