It allows to set the bit time register with tunable values. The setting can only be changed if the interface is down: ip link set dev can0 down ethtool --set-tunable can0 can-btr 0x31c ip link set dev can0 up
As far as I understand, setting the btr is an alternative way to set the bitrate, right? I don't like the idea of poking arbitrary values into a hardware from user space. Do you have a use case for this?
