I see. I now understand why you recommend using mcp251xfd as a template
for m_can.
Am I correct in saying that rx-offload requires RX timestamps to be
available? They can be enabled in M_CAN, but the v3.3 manual states that
the internal timestamp generation (apparently only option for tcan4x5x)
cannot be used for CAN-FD.
