Currently these constants like SOL_CAN_RAW and CAN_RAW_FILTER are not included, neither in zerrors_linux.go nor ztypes_linux.go.

Adding #include <linux/can/raw.h> to mkerrors.sh and linux/types.go as well as adding an enum to the latter would add 7 constants.
These constants are needed to set CAN filters to receive error message frames (see chapter 4.1.2 in SocketCAN documentation):

unix.SetsockoptInt(fd, unix.SOL_CAN_RAW, unix.CAN_RAW_ERR_FILTER, unix.CAN_ERR_MASK)
