The P0_TX_CRC_REMOVE bit in the CPSW_CONTROL_REG register determines if CPPI egress packet have a CRC included or not. If present, the CRC type for all packets is determined by the P0_TX_CRC_TYPE bit in the CPSW Control register. Egress packets not filtered on Ethernet ingress due to PN_RX_CEF_EN have the packet error CRC included (not replaced by the egress CRC type_) if the CRC is not removed on egress. The error is indicated in the buffer descriptor. CPPI egress packets that detected a CRC error on the internally generated Castagnoli CRC, due to a bit flip in logic or memory, will indicate the error with the drop bit set in the buffer descriptor.
