This is true, unless you monitor all j1939 traffic in 'promiscuous'
mode. I'm not sure if that hasn't been thrown away yet, and is something
designed to be used on a PC anyway. You could extend the check a bit.
Same like with ipv4/ipv6/tcp/udp stacks, we do not process unrelated
traffic. We capture RAW Ethernet traffic. In this case, in promiscuous mode we
should capture RAW CAN traffic, not decoded J1939 traffic.
That means a userspace decoder for j1939 promiscuous spying.
That makes sense.
@Kurt, to confirm, you have nothing against this patches?
