Tool/software: Linux
Hello,
The ip command on Sitara Linux (SDK 04.04, Linux 4.9.69) reports error for a CAN device option:
# ip link set can0 type can triple-sampling on
RTNETLINK answers: Operation not supported
The CAN device appears to operate nevertheless.
Other options appear to work, such as
ip link set can0 type can bitrate 100000 berr-reporting off
The ip utility help for CAN shows this option is available
# ip link set can0 type can help
Usage: ip link set DEVICE type can

Would you please advise regarding the 'triple-sampling' CAN option of the ip utility.
Could it be dependent on some configuration parameter in Linux build config?
Thanks
