i.MX6QP with Linux 4.9.170 with CAN RX error issue during CAN bus stress testing.
There are 6 CAN devices connect to the CAN bus, dump CAN status by ifconfig command show CAN RX with errors, and also detected CAN message lost by candump.

Is it a problem of CAN FIFO overflow?
Do you have any suggestions?
thanks.
