Is it possible, that at91_can does also hardware loopback? If I use the default socket options (CAN_RAW_LOOPBACK = 1, CAN_RAW_RECV_OWN_MSGS = 0), I also receive my own frames on the same socket. setting CAN_RAW_RECV_OWN_MSGS to 1 doesn't change anything. But if I set CAN_RAW_LOOPBACK to 0, I don't get any frame I sent. I guess the latter is intended.
