Hi, Since it took me a while to figure it out, it might be worthwhile to share. If a CAN-bus network interface is first set to up and only later used, the messages received in the meantime are counted by [1] as dropped. If the the can module is modprobed before the interface is upped, this is no longer the case. Perhaps it saves someone some time.
