The Broadcast Manager protocol provides a command based configurationinterface to filter and send (e.g. cyclic) CAN messages in kernel space.Filtering messages in kernel space may significantly reduce the load in an application.
A BCM socket is not intended for sending individual CAN frames.To send invidiual frames use thetokio-socketcan crate.
This crate would not have been possible without thesocketcan crate.
