+         The Broadcast Manager offers content filtering, timeout monitoring,
+         sending of RTR frames, and cyclic CAN messages without permanent user
+         interaction. The BCM can be 'programmed' via the BSD socket API and
+         informs you on demand e.g. only on content updates / timeouts.
+         You probably want to use the bcm socket in most cases where cyclic
+         CAN messages are used on the bus (e.g. in automotive environments).
+         To use the Broadcast Manager, use AF_CAN with protocol CAN_BCM.
