CANFD transmit buffer is full.

Hi. I use the spc58nh-disp board.

I'm doing the CANFD gateway test.

I uses CAN0 and CAN1.

After receiving 55(id quantity) rx message from CAN1, CAN0 Transmits 55 messages.

And after receiving one message from CAN0. Transmit to CAN1.

At this time, bus off occurs.

It is assumed that the transmit buffer is full..

How to control the full transmit buffer??
