When the E-tile Hard IP for Ethernet Intel® FPGA IP RX MAC receives frame size >= 65536, and enforce_max_frame_size is enabled, the frame output from RX MAC to user logic will be truncated to the frame size specified by max_rx_frame_size setting. A second invalid frame will output from RX MAC to user logic starting from byte-65536 to end of the super large frame.
