Hi,we just encounter a Ethernet problem during a real-car test: after power-on,messages entering a mac port were lost, while the mac_port's packet sending was normal. After checking, it was found that the port's statistical parameter "CPSW_STAT0_RX_BITTOM_OF_FIFO_DROP" was consistent with the number of packet losses. Have someone knowing the possible causes of this problem,encountered similar issues ,,or have any understanding of this parameter?
