+/* Story: RTP Player, conversation (probably reassemble too) use address:port as
+ "key" to separate devices/streams. In Bluetooth World it is not enough to
+ separate devices/streams. Example key:
+ guint32 interface_id (aka frame.interface_id)
+ guint32 adapter_id (interface like "bluetooth-monitor" or USB provide
+ more than one device over interface, so we must
+ separate information provided by each one)
+ guint16 hci_chandle (aka "connection handle" use to separate connections to devices)
+ guint16 l2cap_psm (like hci_chandle but over l2cap layer, need hci_chandle info because
+ the same PSM can be used over chandles)
+ guint8 rfcomm_channel (like l2cap_psm, but over RFCOMM layer...)
+ etc. like
+ guint8 stram_endpoint_number
+ guint32 stream_number (to separate multiple streams for RTP Player)
+
+ So keys can be various (length or type) and "ports" are not enough to sore
+ all needed information. If one day that changed then all RTP_PLAYER_WORKAROUND
+ block can be removed. This workaround use global number of streams (aka stream ID)
+ to be used as port number in RTP Player to separate streams.
