systemd-networkd also supports CAN configuration, but I this will
probably not work on no-MMU systemd, too.

Then there is:

| https://git.pengutronix.de/cgit/tools/canutils
| https://git.pengutronix.de/cgit/tools/libsocketcan

that contains canconfig, but it lacks CAN-FD support.

Yes, go ahead and upstream your changes!
