It seems to be the only solution… Moving forward, I will do one more round of tests and send the patch for iproute2-next (warning, the RFC I sent last month has some issues, if you wish to test it on your side, please wait). I will also apply can_tdc_is_enabled() to the etas_es58x driver. Could you push the recent changes on the testing branch of linux-can-next? It would be really helpful for me! Yours sincerely, Vincent
