Please try:

# ip link set can0 type can bitrate 125000 dbitrate 8000000 fd on 
fd-non-iso on

The driver for the M_CAN IP core 3.0.x in the mainline kernel supports a 
NON_ISO IP core.

This non-iso setting is fixed with this v3.0.x M_CAN and we decided to 
make this configuration explicit - as all other options run into a mess.

Did that help?
