IPV4 and IPV6 UDP and TCP packets that are received on any Ethernet port and destined for port 0 egress are checked for correct checksum as described below. The EOP Transmit buffer descriptor bit CHKSUM_ENCAP indicates whether or not the transmit checksum information is included with the egress packet or not. If the checksum information is included in the packet, the PACKET_LENGTH includes the four checksum information bytes. The byte counts below are shown for packets with no VLAN’s. The byte counts vary with one or two packet VLAN's. Packets received on an Ethernet port with errors are not checked for a correct checksum if they are passed to the host (no checksum information with the error packet).
