5.1.1.1. Frame Padding

When the length of the client frame is less than 64 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 (including CRC).

The IP core filters out all client frames with lengths less than 9 bytes. The IP core drops these frames silently.
