My goal with this extension is to be able to implement a reliable 'CAN send' function in userspace which would check that the message has been correctly transmitted, or retry if no confirmation was received after a timeout (I am using a device which empties some TX buffer when recovering from the Bus-Off state, therefore some messages will be lost, which is why the reliability needs to be handled elsewhere). For this purpose, knowing the origin of a received message is needed. This was already possible with RAW sockets, and the goal here is to provide the same information when using BCM sockets.
