Low Latency 40- and 100-Gbps Ethernet MAC and PHY MegaCore Function User Guide

Document Table of Contents Frame Padding

When the length of client frame is less than 64 bytes (meaning the payload is less than 46 bytes) and greater than eight bytes, the TX MAC module inserts pad bytes (0x00) after the payload to create a frame length equal to the minimum size of 64 bytes.

The Low Latency 40-100GbE IP core does not process incoming (egress) frames of less than nine bytes correctly. You must ensure such frames do not reach the TX client interface.
