Hi Patrick,

Maybe it was just to a test to see if the the protocol type existed?

It does look like the protocol is defined in include/uapi/linux/can.h:

#define CAN_ISOTP	6 /* ISO 15765-2 Transport Protocol */

However, there does not appear to be any implementation in the mainline
kernel.

I recall Oliver mentioning that he should try to mainline isotp modules
at the end of the J1939 talk at ELC-E last October [1]. I don't see any
posts regarding isotp in the linux-can archives since then, so I thought
I would bring it up.

Thanks,
Drew
