Well it took longer... But here comes the report on our experience with ISO-
TP:

We tested successfully against two other proprietary ISO-TP CAN 
implementations with isotpsend and isotprecv without any problems.

We did not use the j1939 branch up to now.

Hello Markus,

thanks for the feedback on the ISO-TP implementation.

Indeed we're also using it every day and i did not see any issues for a long
time now.

The missing thing is that you currently need to set the tx_queue_len of the
according network device to high values (like 1000) as the ISO-TP
implementation does not react on full tx queues 8-)

Regards,
Oliver
