This adds broadcast support for BTPROTO_ISO by extending the sockaddr_iso with a new struct sockaddr_iso_bc where the socket user can set the broadcast address when receiving, the SID and the BIS indexes it wants to synchronize. When using BTPROTO_ISO for broadcast the roles are: Broadcaster -> uses connect with address set to BDADDR_ANY: > tools/isotest -s 00:00:00:00:00:00 Broadcast Receiver -> uses listen with address set to broadcaster: > tools/isotest -d 00:AA:01:00:00:00 Signed-off-by: Luiz Augusto von Dentz <luiz.von.dentz@intel.com>
