4.2.2. Receive RX Path

The receiving Ethernet frames from the Ethernet MAC first enters packet classifier block. Packet classifier block classifies the packet into eCPRI packets and non-eCPRI packets. The packet classifier sends eCPRI packets with matching MAC address to the Ethernet header removal block of the eCPRI IP, while sends all other non-eCPRI packets or eCPRI packets with non-matching MAC address to external user logic for processing. For detailed information on conditions when the IP classifies packet as eCPRI packet, refer to section Packet Classifier.
