Hello, Thanks for the response. I am using can_get_state() as part of my start_CAN routine. After, I call can_do_start(), I read the state to see if I need to do bus-off recovery. So it is not a frequent call. I was able to see the states correctly on all four CAN channels with "ip -d -s link".
I updated the code in plx_pci.c to include support for the IXXAT card. I wanted to ask you how to submit the changes since I have not done it before. I attached a patch file.

Hm, if "ip -d -s link" lists the state correctly, then it's most likely a problem with libsocketcan. Anyway, for what purpose would you like to use can_get_state()? It's not forseen for frequent polling of the CAN error state. Please use error messages instead. > I would appreciate any advice, this seems like a strange problem to me. What Socket-CAN driver are you using for the IXXAT cards? There is still no support in mainline Linux, IIRC. Maybe there is some mismatch with the header files. Hope it helps. Wolfgang.
