Hello Oliver, I was wondering what the RX, TX and echo semantics on vxcan interfaces should be. I have started a "cangen" in one namespace and a "candump" in other. The "candump" in the receiving namespace shows the CAN frames as "TX" and in the sending namespace the CAN frames don't show up in a "candump" at all. Is this intentional? If so what's the idea behind this and is this documented? I'm adding "cangw" to the mix and see what happens.... regards, Marc -- Pengutronix e.K. | Marc Kleine-Budde | Embedded Linux | https://www.pengutronix.de | Vertretung West/Dortmund | Phone: +49-231-2826-924 | Amtsgericht Hildesheim, HRA 2686 | Fax: +49-5121-206917-5555 |
