2.2. Supported Features

The IP core handles the frame encapsulation and flow of data between client logic and an Ethernet network through 10Gbps, 25Gbps, 40Gbps, 50Gbps, 100Gbps, 200Gbps and 400Gbps Ethernet PHY with optional Forward Error Correction (FEC). The client data interface is implemented on AXI4-Streaming interface and AXI4-Lite interface for register access.
