ENIB

The Ethernet Network Interface Block (ENIB) converts Ethernet data packets
received through front panel ports into a common canonical format that allows
the SmartSwitch ASIC Engine to determine the proper destination port. The ENIB
also converts data packets from the common canonical format back to Ethernet
data packets for transmission out front panel ports.
