SPINEL_PROP_STREAM_NET value

(IPv6) Network Stream Format: `dD` (stream, read only) This stream provides the capability of sending and receiving (IPv6) data packets to and from the currently attached network. The packets are sent or received securely (encryption and authentication). This property is a streaming property, meaning that you cannot explicitly fetch the value of this property. To receive traffic, you wait for `CMD_PROP_VALUE_IS` commands with this property id from the NCP. To send network packets, you call `CMD_PROP_VALUE_SET` on this property with the value of the packet. The general format of this property is: `d` : packet data `D` : packet meta data The packet metadata is optional. Packet meta data MAY be empty or partially specified. Partially specified metadata MUST be accepted. Default values are used for all unspecified fields. For OpenThread the meta data is currently empty.
