Oversized RX Frame

At RX, every decoded RX frame is checked for its physical frame length and compared with the user’s configured Maximum Transmission Unit Frame Length. If the physical frame length is greater than the Maximum Transmission Unit Frame Length, it is flagged as an oversized RX frame. When this occurs, the Ethernet 10G MAC core asserts RX_AXI_TUSER and increments the RX statistic reporting, cnt_rx_frame_oversized. Figure 1 describes an oversized RX frame.
