This is useful for the broadcast sink scenario: the userspace opens a socket and starts listening for a PA sync connection. If the PA is associated with an encrypted BIG, the userspace needs to be informed. After PA sync has been successfully established and the first BIGInfo advertising report is received, a new hcon is added and notified to the ISO layer. The ISO layer sets the encryption field of the socket and hcon QoS according to the encryption parameter of the BIGInfo advertising report event. After that, the userspace is woken up, and the QoS of the new PA sync socket can be read, to inspect the encryption field and follow up accordingly.
