Subject: [PATCH 2/3] Bluetooth: Implement support for Mesh
Date:   Thu, 31 Mar 2022 11:07:48 -0700
Message-Id: <20220331180749.456913-3-brian.gix@intel.com>
In-Reply-To: <20220331180749.456913-1-brian.gix@intel.com>
References: <20220331180749.456913-1-brian.gix@intel.com>
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit
Precedence: bulk

The patch adds state bits, storage and HCI command chains for sending
and recieving Bluetooth Mesh advertising packets, and delivery to
requesting user space processes. It specifically creates 4 new MGMT
commands and 2 new MGMT events:

MGMT_OP_SET_MESH_RECEIVER - Sets passive scan parameters and a list of
AD Types which will trigger Mesh Packet Received events

MGMT_OP_MESH_READ_FEATURES - Returns information on how many outbound
Mesh packets can be simultaneously queued, and what the currently queued
handles are.

MGMT_OP_MESH_SEND - Command to queue a specific outbound Mesh packet,
with the number of times it should be sent, and the BD Addr to use.

MGMT_OP_MESH_SEND_CANCEL - Command to cancel a prior outbound message
request.

MGMT_EV_MESH_DEVICE_FOUND - Event to deliver entire received Mesh
Advertisement packet, along with timing information.

MGMT_EV_MESH_PACKET_CMPLT - Event to indicate that an outbound packet is
no longer queued for delivery.
