The CPPI host port can be enabled to perform checksum offload on host port packet ingress and egress. UDP (User Datagram Protocol) and TCP (Transmission Control Protocol) over IPV4 and IPV6 are supported. For the purposes of checksum description, the first packet byte (the first byte of the destination address) is byte 1 (not byte 0). That is, a 64 byte packet goes from byte 1 to byte 64. For all packet types, the S_CN_SWITCH bit in the CPSW_CONTROL_REG register must be set for the Outer VLAN L type to be supported.
