All ports (non cut-thru mode)
The total number of frames received on a port that were dropped (zero PORT_MASK) due to exceeding the maximum ALE lookup rate (Port 0 should not have ALE Overrun Drops because the ingress rate is controlled to prevent it). This statistic should be zero and when non-zero indicates a system clock issue or indicates that short packets were sent with RX_CSF_EN at a rate that exceeded the maximum lookup rate.
Ethernet Ports (cut-thru mode)
The total number of received frames on a port that were dropped due to packet errors. This statistic does not count error frames that are sent to the host with a set CPSW3_CPSW_NU_CPSW_NU_ETH_MAC_i_PN_MAC_CONTROL_REG[22] RX_CEF_EN or CPSW3_CPSW_NU_CPSW_NU_ETH_MAC_i_PN_MAC_CONTROL_REG[24] RX_CMF_EN.
