I think the socket option CAN_RAW_LOOPBACK is what you need. Please refer to
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/tree/Documentation/networking/can.txt#n536
You will not receive CAN frames sent from interface (BCM and other CAN
frames), thus only messages from other CAN nodes.
HTH
