Works wonderfully loaded into the Ubuntu 5.4.0-56 and a 2.6.31 custom kernel. I can ditch all the RX-path-settings and just use the flag without any errors. EINVAL gets triggered as expected for too long messages. All default ISO-TP sockets stay unharmed. Wonderful, thanks for the quick solution! Regards Thomas
