Each CPSW egress port (Ethernet and Host) is capable of performing egress packet processing operations (CPSW_ALE_EGRESSOP). IntraVLAN processing either adds, removes, or replaces VLAN information or does nothing. InterVLAN routing allows hardware routing between a limited number of VLANs - thereby allowing high-bandwidth or other routing operations to be offloaded from software to the CPSW (hardware). IntraVLAN processing and InterVLAN routing operations are mutually exclusive. In addition, the packet source and destination addresses can be swapped on egress to facilitate OAM or generic testing operations.
