Thanks for pointing that out! /me might need new glasses :)
The can0->can1 test is now working with mcp251xfd:
pi@raspberrypi:~$ sudo ip link set can0 type can bitrate 250000
pi@raspberrypi:~$ sudo ip link set can1 type can bitrate 250000
pi@raspberrypi:~$ sudo ifconfig can0 up
pi@raspberrypi:~$ sudo ifconfig can1 up
pi@raspberrypi:~$ dmesg |tail
